EMISSION CONTROL INFORMATION

To protect the environment in which we all live, Kawasaki has incorporated crankcase emission

(1) and exhaust emission (2) control systems in compliance with applicable regulations of the

United States Environmental Protection Agency and California Air Resources Board.

1. Crankcase Emission Control System

A sealed-type crankcase emission control system is used to eliminate blow-by gases. The blow

-by gases are led to the breather chamber through the crankcase. Then, it is led to the intake manifold.

Oil is separated from the gases while passing through the inside of the breather chamber from the crankcase, and then returned to the bottom of the crankcase.

2. Exhaust Emission Control System

The exhaust emission control system applied to this engine family is engine modifications that consist of a modified carburetor and ignition system having optimum ignition timing characteristics.

The carburetor has been calibrated to provide lean air/fuel mixture characteristics and optimum fuel economy with a suitable air cleaner and exhaust system.

A maintenance free ignition system provides the most favorable ignition timing and helps maintain a thorough combustion process within the engine which contributes to a reduction of exhaust pollutants entering the atomosphere.

The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is commonly referred to as the Act’s "tampering provisions."

"Sec. 203(a) The following acts and the causing thereof are prohibited...

(3)(A) for any person to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser.

(3)(B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles knowingly to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title following its sale and delivery to the ultimate purchaser..."

NOTE

The phrase "remove or render inoperative any device or element of design" has been generally interpreted as follows:

1. Tampering does not include the temporary removal or rendering inoperative of devices or elements of design in order to perform maintenance.

2. Tampering could include: a.Maladjustment of vehicle components such that the emission standards are exceeded.

b.Use of replacement parts or accessories which adversely affect the performance or durability of the vehicle.

c.Addition of components or accessories that result in the vehicle exceeding the standards.

d.Permanently removing, disconnecting, or rendering inoperative any component or element of design of the emission control systems.

WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL

LAW, THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING

$10,000 PER VIOLATION.

Property of www.SmallEngineDiscount.com - Not for Resale

PLEASE DO NOT TAMPER WITH NOISE CONTROL SYSTEM

(United States Model only)

To minimize the noise emissions from this product, Kawasaki has equipped it with effective intake and exhaust silencing systems. They are designed to give optimum performance while maintaining a low noise level. Please do not remove these systems, or alter them in any way which results in an increase in noise level.

1-2 GENERAL INFORMATION

Before Servicing

Before starting to perform an inspection service or carry out a disassembly and reassembly operation on a vehicle, read the precautions given below. To facilitate actual operations, notes, illustrations, photographs, cautions, and detailed descriptions have been included in each chapter wherever necessary. This section explains the items that require particular attention during the removal and reinstallation or disassembly and reassembly of general parts.

Especially note the following:

Battery Ground

Before completing any service on the vehicle, disconnect the battery wires from the battery to prevent the engine from accidentally turning over. Disconnect the ground wire (–) first and then the positive (+). When completed with the service, first connect the positive (+) wire to the positive

(+) terminal of the battery then the negative (–) wire to the negative terminal.

Edges of Parts

Lift large or heavy parts wearing gloves to prevent injury from possible sharp edges on the parts.

Solvent

Use a high-flush point solvent when cleaning parts. High

-flush point solvent should be used according to directions of the solvent manufacturer.

Cleaning vehicle before disassembly

Clean the vehicle thoroughly before disassembly. Dirt or other foreign materials entering into sealed areas during vehicle disassembly can cause excessive wear and decrease performance of the vehicle.

Property of www.SmallEngineDiscount.com - Not for Resale

Before Servicing

Arrangement and Cleaning of Removed Parts

Disassembled parts are easy to confuse. Arrange the parts according to the order the parts were disassembled and clean the parts in order prior to assembly.

GENERAL INFORMATION 1-3

Storage of Removed Parts

After all the parts including subassembly parts have been cleaned, store the parts in a clean area. Put a clean cloth or plastic sheet over the parts to protect from any foreign materials that may collect before re-assembly.

Inspection

Reuse of worn or damaged parts may lead to serious accident. Visually inspect removed parts for corrosion, discoloration, or other damage. Refer to the appropriate sections of this manual for service limits on individual parts. Replace the parts if any damage has been found or if the part is beyond its service limit.

Replacement Parts

Replacement Parts must be KAWASAKI genuine or recommended by KAWASAKI. Gaskets, O-rings, Oil seals,

Grease seals, circlips or cotter pins must be replaced with new ones whenever disassembled.

Assembly Order

In most cases assembly order is the reverse of disassembly, however, if assembly order is provided in this Service

Manual, follow the procedures given.

1-4 GENERAL INFORMATION

Before Servicing

Tightening Sequence

Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them according to the specified sequence to prevent case warpage or deformation which can lead to malfunction. Conversely when loosening the bolts, nuts, or screws, first loosen all of them by about a quarter turn and then remove them. If the specified tightening sequence is not indicated, tighten the fasteners alternating diagonally.

Tightening Torque

Incorrect torque applied to a bolt, nut, or screw may lead to serious damage. Tighten fasteners to the specified torque using a good quality torque wrench.

Often, the tightening sequence is followed twice initial tightening and final tightening with torque wrench.

Force

Use common sense during disassembly and assembly, excessive force can cause expensive or hard to repair damage. When necessary, remove screws that have a non

-permanent locking agent applied using an impact driver.

Use a plastic-faced mallet whenever tapping is necessary.

Gasket, O-ring

Hardening, shrinkage, or damage of both gaskets and O-rings after disassembly can reduce sealing performance.

Remove old gaskets and clean the sealing surfaces thoroughly so that no gasket material or other material remains. Install new gaskets and replace used

O-rings when re-assembling.

Liquid Gasket, Locking Agent

For applications that require Liquid Gasket or a

Non-Permanent Locking Agent, clean the surfaces so that no oil residue remains before applying liquid gasket or locking agent. Do not apply them excessively. Excessive application can clog oil passages and cause serious damage.

Before Servicing

Press

For items such as bearings or oil seals that must be pressed into place, apply small amount of oil to the contact area. Be sure to maintain proper alignment and use smooth movements when installing.

GENERAL INFORMATION 1-5

Ball Bearing and Needle Bearing

Do not remove pressed ball or needle unless removal is absolutely necessary. Replace with new ones whenever removed. Press bearings with the manufacturer and size marks facing out. Press the bearing into place by putting pressure on the correct bearing race as shown.

Pressing the incorrect race can cause pressure between the inner and outer race and result in bearing damage.

Oil Seal, Grease Seal

Do not remove pressed oil or grease seals unless removal is necessary. Replace with new ones whenever removed.

Press new oil seals with manufacture and size marks facing out. Make sure the seal is aligned properly when installing.

Apply specified grease to the lip of seal before installing the seal.

Circlips, Cotter Pins

Replace circlips or cotter pins that were removed with new ones. Take care not to open the clip excessively when installing to prevent deformation.

1-6 GENERAL INFORMATION

Before Servicing

Lubrication

It is important to lubricate rotating or sliding parts during assembly to minimize wear during initial operation. Lubrication points are called out throughout this manual, apply the specific oil or grease as specified.

Direction of Engine Rotation

When rotating the crankshaft by hand, the free play amount of rotating direction will affect the adjustment. Rotate the crankshaft to positive direction (clockwise viewed from output side).

Electrical Wires

A two-color wire is identified first by the primary color and then the stripe color. Unless instructed otherwise, electrical wires must be connected to those of the same color.

If the throttle pedal does not return properly, lubricate the throttle cable and link (see Fuel System chapter).

Check the throttle pedal free play [A].

Throttle Pedal Free Play

Standard: 2

5 mm (0.08

0.20 in.)

If the free play is incorrect, adjust the throttle cable.

Throttle Pedal Free Play Adjustment

Tilt up the cargo bed.

Loosen the adjuster mounting nuts [A] at the cable lower end.

Slide the adjuster [B] until the proper amount of throttle pedal free play is obtained.

Tighten the mounting nuts securely.

Start the engine.

With the transmission in neutral, operate the throttle pedal a few times to make sure that the idle speed does not change.

If the idle speed does change, the throttle cable may be improperly adjusted, incorrectly routed, or it may be damaged.

Correct any of these conditions before operation.

WARNING

Operation with improperly adjusted, incorrectly routed, or a damaged cable could result in an unsafe operating condition.

NOTE

If the throttle pedal free play cannot be adjusted by using the adjuster at the cable lower end, use the cable adjuster [A] at the cable upper end. Do not forget to securely tighten the adjuster mounting nuts [B].

Idle Speed Inspection

Start the engine and warm it up thoroughly.

Tilt up the cargo bed.

Check the idle speed with a suitable tachometer.

Idle Speed

Standard: 1 100

1 250 r/min (rpm)

1 250 r/min (rpm)

After the adjustment, screw in the idle adjusting screw [A] on the link bracket until the screw lightly touches the link lever [B].

Finally screw in the accel lever stopper screw [C] until it keeps clearance by 1 mm (0.04 in.) to accel lever [D].

Depress and release the throttle pedal a few times to make sure that the idle speed does not change. Readjust if necessary.

Air Cleaner Element Cleaning

NOTE

In dusty areas, the element should be cleaned more frequently than the recommended interval.

After riding through rain or on muddy roads, the element should be cleaned immediately.

WARNING

Clean the element in a well-ventilated area, and take ample care that there are no sparks or flame anywhere near the working area.

Because of the danger of highly flammable liquids, do not use gasoline or a low flash-point solvent to clean the element.

Foam Element [A]

Paper Element [B]

Clean the foam element in a bath of high flash-point solvent using a soft bristle brush.

Squeeze it dry in a clean towel.

CAUTION

Do not wring the element or blow it dry; the element can be damaged.

Inspect the foam element for damage.

If it is torn, punctured, or hardened, replace it.

NOTE

Replace the foam element after cleaning it five times or if it is damaged.

Clean the paper element by tapping it lightly to loosen dust.

Blow away the remaining dust by applying compressed air from the inside to the outside (from the clean side to the dirty side).

Inspect the element material for damage.

If any part of the element is damaged, the element must be replaced.

Fuel Hoses And Connections Inspection

Lift up the cargo bed and seat.

Check the fuel hoses and fittings for deterioration, cracks and signs of leakage.

Replace the fuel hose if any fraying, leak [A], cracks [B] or bulges [C] are noticed.

Check that the hoses are securely connected and clamps are installed correctly.

When installing, route the hoses according to Cable,

Wire, and Hose Routing section in the Appendix chapter.

When installing the fuel hoses, avoid sharp bending, kinking, flattening or twisting, and route the fuel hoses with a minimum of bending so that the fuel flow will not be obstructed.

Replace the hose if it has been sharply bent or kinked.

Property of www.SmallEngineDiscount.com - Not for Resale

Periodic Maintenance Procedures

Fuel Hoses Replacement

Tilt up the cargo bed and seat.

Slide out the clamps [A].

Remove the hoses [B] (see Exploded View in Fuel System chapter).

Converter System

Drive Belt Inspection

Remove the driver belt (see Converter System chapter).

Measure the width [A] of the belt at several locations with a pair of suitable straightedges [B] as shown.

If any measurements exceed the service limit, replace the belt.

Belt Width

Standard: 26.1

27.3 mm (1.03

Service Limit: 25.2 mm (0.99 in.)

Check the belt for wear, cracks, breaks or peeling.

If necessary, replace the belt with a new one.

Belt [A]

Crack [B]

Broken [C]

NOTE

Whenever the belt is replaced, inspect the drive and the driven pulleys.

Drive Belt Deflection Inspection

Remove the torque converter cover (see Converter System chapter).

Put the transmission in neutral and rotate the driven pulley by hand to make sure the belt is shifted all the way to the top of the driven pulley.

Measure the belt deflection [A] at the three locations by rotating the pulley as shown:

Place a straightedge [B] on top of the belt between the drive pulley [C] and the driven pulley [D].

Use a ruler to push the belt away from the straightedge.

Push hard, but with no more force than 59 N (6 kgf, 13 lb).

Belt Deflection

Standard: 22

32 mm (0.87

1.26 in.)

Service Limit: 22

50 mm (0.87

1.97 in.)

If the belt deflection of all of the three locations is within the specified range, the deflection is normal.

If the belt deflection is not within the specified range, first measure the drive belt width (see Drive Belt Inspection).

Adjust the deflection by adding or removing shims under the deflection bolts.

When adjusting the deflection, less is better than more.

Less deflection will maintain better performance for more time as the belt width decreases by normal wear, which causes the deflection to increase with usage.

Even if the deflection is adjusted, when the belt deflection is greater than the service limit, replace the drive belt.

If the belt deflection is more than 50 mm (1.97 in.), remove the deflection bolts [A] and shims [B] to decrease it.

The rule-of-thumb is: 0.1 mm (0.004 in.) change in shim thickness equals about 1.4 mm (0.055 in.) change in belt deflection.

If the belt deflection is less than 22 mm (0.87 in.), add the shims to increase it.

Electrolyte Specific Gravity Inspection

WARNING

Electrolyte contains sulfuric acid which is harmful to skin, eyes, and clothing.

Wear eye protection and rubber gloves.

If spillage occurs on body or clothing, rinse at once with water for at least 15 minutes.

Check battery condition by testing the specific gravity of the electrolyte in each cell with a hydrometer.

Read the level of the electrolyte [A] on the floating scale.

Specific Gravity

Standard: 1.270 @20°C (68°F)

If the specific gravity is below 1.200 (charge 70%), the battery needs to be charged.

NOTE

The specific gravity of the electrolyte varies with changes in temperature, so the specific gravity reading must be corrected for the temperature of the electrolyte.

Celsius: Add 0.007 points to reading for each 10°C above 20°C or subtract 0.007 points for each 10°C below 20°C

Fahrenheit: Add 0.004 points to reading for each 10°F above 68°F or subtract 0.004 points for each 10°F below 68°F.

If the specific gravity of any of the cells is more than 0.050

away from any other reading, the battery will probably not accept a charge. It is generally best to replace a battery in this condition.

If the specific gravity of all the cells is 1.270 or more, the battery is fully charged.

Carburetor Cleaning

WARNING

Clean the carburetor in a well-ventilated area, and take care that there is no spark or flame anywhere near the working area; this includes any appliance with a pilot light. Because of the danger of highly flammable liquids, do not use gasoline or low-flashpoint solvents to clean the carburetor.

CAUTION

Do not use compressed air on an assembled carburetor, the float may be crushed by the pressure.

Remove as many rubber or plastic parts from the carburetor as possible before cleaning the carburetor with a cleaning solution. This will prevent damage or deterioration of the parts. The carburetor body has plastic parts that cannot be removed. Do not use a strong carburetor cleaning solution which could attack these parts; instead, use a mild high flash point cleaning solution safe for plastic parts.

Do not use wire or any other hard instrument to clean carburetor parts, especially jets, as they may be damaged.

Disassemble the carburetor.

Immerse all the metal parts in a carburetor cleaning solution.

Rinse the parts in water.

When the parts are clean, dry them with compressed air.

Blow through the air and fuel passages with compressed air.

Assemble the carburetor.

Cylinder Compression Measurement

Tilt up the cargo bed.

Thoroughly warm up the engine so that the engine oil between the piston and the cylinder wall will help seal compression as it does during normal running.

Stop the engine, remove the spark plug, and attach a compression gauge [A] firmly into the spark plug hole.

Special Tools - Compression Gauge, 20 kgf/cm²: 57001-221

Compression Gauge Adapter, M14 × 1.25

[B]: 57001-1159

Using the starter motor, turn the engine over with the throttle fully open until the compression gauge stops rising; this is the highest compression reading obtainable.

Cylinder Compression

Usable Range:

340

590 kPa (3.5

6.0 kgf/cm², 50

85 psi) @530 r/min (rpm)

Repeat the measurement to the other cylinder.

The following table should be consulted if the obtainable compression reading is not within the usable range.

Remedy (Action)

Remove the carbon deposits and replace damaged parts if necessary.

Cylinder compression higher than usable range

Problem Diagnosis

Carbon accumulation on piston and cylinder head, and in combustion chamber possibly due to damaged valve stem oil seal and/or damaged piston oil rings

Incorrect cylinder head gasket thickness

Gas leakage around cylinder head Cylinder compression lower than usable range

Bad condition of valve seating

Incorrect valve, piston/cylinder clearance

Piston seizure

Bad condition of piston ring and/or piston ring grooves

Replace with a gasket of the proper thickness.

Replace damaged gasket and check cylinder head warp.

Valve Seat Cutter Holder Bar: 57001-1128

If the manufacture’s instructions are not available, use the following procedure.

Seat Cutter Operating Cares

1. The valve seat cutter is designed only for valve seat repair. Therefore the cutter must not be used for other purposes.

2. Do not drop or hit the valve seat cutter, or the diamond particles may fall off.

3. Do not fail to apply engine oil to the valve seat cutter before grinding the seat surface. Also wash off ground particles sticking to the cutter with washing oil.

NOTE

Do not use a wire brush to remove the metal particles from the cutter. It will take off the diamond particles.

4. Setting the valve seat cutter holder [A] in position, operate the cutter [B] with one hand [C]. Do not apply too much force to the diamond portion.

NOTE

Prior to grinding, apply oil to the cutter, and during the operation wash off any ground particles sticking to the cutter with washing oil.

5. After use wash the cutter with washing oil and apply a thin layer or engine oil before storing.

Marks Stamped on the Cutter

The marks stamped on the back of the cutter [A] represent the following.

Operating Procedures

Clean the seat area carefully.

Coat the seat with machinist’s dye.

Fit a 45° cutter to the holder and slide it into the valve guide.

Press down lightly on the handle and turn it right or left.

Grind the seating surface only until it is smooth.

CAUTION

Do not grind the seat too much. Overgrinding will reduce valve clearance by sinking the valve into the head. If the valve sinks too far into the head, it will be impossible to adjust the clearance, and the cylinder head must be replaced.

Measure the outside diameter (O.D.) of the seating surface with a vernier caliper.

If the O.D. of the seating surface is too small, repeat the

45° grind until the diameter is within the specified range.

If the O.D. of the seating surface is too large, make the

32° grind described below.

Grind the seat at a 32° angle until the seat O.D. is within the specified range.

To make the 32° grind, fit a 32° cutter to the holder, and slide it into the valve guide.

Turn the holder one turn at a time while pressing down very lightly. Check the seat after each turn.

CAUTION

The 32° cutter removes material very quickly.

Check the seat outside diameter frequently to prevent overgrinding.

After making the 32° grind, return to the seat O.D. measurement step above.

Lap the valve to the seat, once the seat width and O.D.

are within the ranges specified above.

Put a little coarse grinding compound on the face of the valve in a number of places around the valve head.

Spin the valve against the seat until the grinding compound produces a smooth, matched surface on both the seat and the valve.

Repeat the process with a fine grinding compound.

[A] Lapper

[B] Valve Seat

[C] Valve

The seating area should be marked about in the middle of the valve face.

If the seat area is not in the right place on the valve, check to be sure the valve is the correct part. If it is, it may have been refaced too much; replace it.

Be sure to remove all grinding compound before assembly.

When the engine is assembled, be sure to adjust the valve clearances (see Valve Clearance Adjustment).

Engine Oil and Oil Filter

WARNING

Vehicle operation with insufficient, deteriorated, or contaminated engine oil will cause accelerated wear and may result in engine seizure, accident, and injury.

Oil Level Inspection

NOTE

If the vehicle has just been used, wait several minutes for all the oil to drain down.

If the oil has just been changed, start the engine and run it for several minutes at idle speed. This fills the oil filter with oil. Stop the engine, then wait several minutes until the oil settles.

CAUTION

Racing the engine before the oil reaches every part can cause engine seizure.

Park the vehicle on level ground, and tilt up the seat.

Remove:

Cap

Pull out the oil level gauge [A] and wipe it dry.

Apply engine oil to the rubber seal lip [A] on the dipstick.

Insert the oil level gauge into the oil filler hole securely.

CAUTION

Always insert the oil level gauge into the oil filler hole so that the taper part [A] of the cap is facing rearwards.

Property of www.SmallEngineDiscount.com - Not for Resale

ENGINE LUBRICATION SYSTEM 6-7

Engine Oil and Oil Filter

Pull out the oil level gauge and check the oil level. The oil level should be between the “H”(High) and “L”(Low) lines

[A] on the dipstick.

If the oil level is too high, remove the excess oil, using a syringe or some other suitable device, or removing the engine oil drain plug, drain the excess oil.

If the oil level is too low, add the correct amount of oil through the oil filler hole. Use the same type and make of oil that is already in the engine.

NOTE

If the engine oil type and make are unknown, use any brand of the specified oil to top up the level in preference to running the engine with the oil level low. Then at your earliest convenience, change the oil completely.

Install the oil level gauge securely.

Breather

The function of the breather is to create a negative pressure in the crankcase which prevents oil from being forced out of the engine through the piston rings, oil seals or gaskets. A sealed-type crankcase emission control system is used to prevent blow-by gases from emitting in the air. The blow-by gases are drawn into the clean side of the air cleaner through the crankcase and the cylinder head and mixed with the clean air flow, and subsequently comes into the combustion chamber through the carburetor.

Oil is primarily separated from the gases while passing through the inside of the rocker chamber from the crankcase, and secondly separated from the gases in the breather chamber, and then brought back to the crankcase.

Transmission Oil

CAUTION

Vehicle operation with insufficient, deteriorated or contaminated transmission oil will cause accelerated wear and may result in transmission failure.

Transmission Oil Level Inspection

NOTE

If the vehicle has just been used wait several minutes for all the oil to settle down.

Park the vehicle on level ground, and tilt up the cargo bed.

Unscrew the oil gauge [A], wipe its dipstick [B] dry, and insert it into the filler opening but DO NOT SCREW IT IN.

Pull out the dipstick and check the oil level. The oil level should be between the upper (H) and lower (L) level lines

[C].

If the oil level is too high, remove the excess oil, using a syringe or some other suitable device, through the oil filler opening.

If the oil level is too low, add the necessary amount of oil through the oil filler opening. Use the same type and make of oil that is already in the transmission.

NOTE

If the transmission oil type and make are unknown, use any brand of the specified oil to top up the level in preference to running the transmission with the oil level low.

Then, at your earliest convenience, change the oil completely.

Wheel Alignment

Toe-in is the amount that the front wheels are closer together in front than at the rear at the axle height. When there is toe-in, the distance A (Rear) is greater than B

(Front) as shown. The purpose of toe-in is to prevent the front wheels from getting out of parallel at any time, and to prevent any slipping or scuffing action between the tires and the ground. If toe-in is incorrect, the front wheels will be dragged along the ground, scuffing and wearing the tread knobs.

Caster and camber are built-in and require no adjustment.

A (Rear) – B (Front) = Amount of Toe-in

(Distance A and B are measured at hub height)

Toe-in Adjustment

Lift the front wheels off the ground.

Apply a heavy coat of chalk near the center of the front tires.

Using a needle nose scriber, make a thin mark near the center of the chalk coating while turning the wheel.

Set the wheels so that the marks on the tires are at the front side and at the level of the axle height.

Ground the front wheels.

Set the steering wheel straight ahead.

At the level of the axle height, measure the distance between the scribed lines with a measure.

Move the vehicle rearward until the marks on the front tires are at the rear side and at the same level as the axle.

Measure the distance [A] between the scribed lines.

Subtract the measurement of the front from the measurement of the rear to get the toe-in.

Toe-in of Front Wheels

Standard: 0

20 mm (0

0.79 in.) at 1G

If the toe-in is not the specified value, perform the following procedure.

Check the length [A] of the tie-rod distance between the flange end [B] and the locknut [C].

Tie-rod Length (distance between flange end and locknut)

Standard: about 34 mm (1.34 in.)

If the length is out of the specified, adjust the tie-rod length.

Loosen the locknut and turn the adjusting rod [D] to achieve the specified value.

NOTE

The toe-in will be near the specified range, if the tie-rod length is the specified value on the left and right.

Tighten:

Check the tire for wear and damage.

Replace the air valve with a new one.

CAUTION

Replace the air valve whenever the tire is replaced.

Do not reuse the air valve.

Lubricate the tire beads and rim flanges with a soap and water solution, or water.

WARNING

Do not use any lubricant other than a water and soap solution, or water to lubricate the tire beads and rim because it may cause tire separation, and a hazardous condition may result.

Install the tire on the rim using a suitable commercially available tire changer.

Lubricate the tire beads again and center the tire on the rim.

Support the wheel rim [A] on a suitable stand [B] to prevent the tire from slipping off.

Inflate the tire until the tire beads seat on the rim.

Maximum Tire Air Pressure (to seat beads when cold)

Front and Rear: 250 kPa (2.5 kgf/cm², 36 psi)

WARNING

Do not inflate the tire to more than the maximum tire air pressure. Overinflation can explode the tire with possibility of injury and loss of life.

Tires

Check to see that the bead lines [A] on both sides of the tire are parallel with the rim flanges [B].

If the bead lines and the rim flanges are not parallel, deflate the tire, lubricate the sealing surfaces again, and re-

• inflate the tire.

After the beads are properly seated, check for air leaks.

Apply a soap and water solution around the tire bead and check for bubbles.

Check the tire pressure using an air pressure gauge [A].

NOTE

Kawasaki provides the air pressure gauge (P/N 52005

-1031) as the owner’s tool.

Tire Air Pressure (when cold)

Front 46.7 kPa (0.5 kgf/cm², 7 psi)

Install the wheel (see Wheel Installation).

Wipe off the soap and water solution, or water on the tire, and dry the tire before operation.

WARNING

Do not operate the vehicle with the water and soap, or water still around the tire beads. They will cause tire separation, and a hazardous condition may result.

WARNING

Inflate both front tires to the same pressure and both rear tires to the same pressure. Operating with unequally or improperly pressurized tires can adversely affect steering or handling.

Front Final Gear Case (KAF400-A/C)

Front Final Bevel Gear Adjustment

In order to prevent one gear from moving away from the other gear under load, the pinion gear must be properly pre-

loaded. Also the backlash (distance one gear will move back and forth without moving the other gear) and tooth

contact pattern of the bevel gears must be correct to prevent the gears from making noise and being damaged.

Above three adjustments are of critical importance and must be carried out following the correct sequence and method.

When any one of the backlash-related parts are replaced or the pinion gear nut is loosened; even if the purpose is not to replace the parts, check and adjust the pinion gear preload, the bevel gear backlash, and tooth contact by replacing shims.

The amount of backlash is influenced by the ring gear position more than by the pinion gear position.

Tooth contact location is influenced by pinion gear position more than by ring gear position.

Pinion Gear Preload Adjustment:

Check and adjust the pinion gear preload in the following cases.

When any of the parts listed below are replaced with new ones.

Pinion Gear

Shims

Ball Bearings

Install the pinion gear and tighten the pinion gear nut to the specified torque.

Torque - Pinion Gear Nut: 156 N·m (16 kgf·m, 115 ft·lb)

Do not install the oil seal, and do not lock the bearing holder until the correct preload is obtained.

CAUTION

To start with, choose a shim so that the bevel gears are just SNUG with NO play but also with NO preload.

An over-preload on the gears could damage the gears.

Measure the pinion gear preload. The preload is the force or torque which is needed to start the gear shaft turning.

Check and adjust the gear backlash when any of the backlash-related parts are replaced with new ones.

Clean any dirt and oil off the bevel gear teeth.

Assemble the front final gear case (see Front Final Gear

Case Assembly). Do not apply liquid gasket during adjustment.

Check the backlash during tightening of the ring gear cover bolts and stop tightening them immediately if the backlash disappears. Then, change the ring gear shim to a thinner one.

Set up a dial gauge against a spline of pinion gear shaft to check gear backlash shown.

To measure the backlash, move the pinion gear back and forth while holding the front axle steady. The difference between the highest and the lowest gauge reading is the amount of backlash.

If the backlash is not within the limit, replace the ring gear shims. To increase backlash, decrease the thickness of the shim(s). To decrease backlash, increase the thickness of the shim(s).

Change the thickness a little at a time.

Tooth Contact Adjustment

Clean any dirt and oil off the bevel gear teeth.

Apply checking compound to 4 or 5 teeth on the pinion gear.

NOTE

Apply checking compound to the teeth in a thin, even coat with a fairly stiff paint brush. If painted too thickly, the exact tooth pattern may not appear.

The checking compound must be smooth and firm, with the consistency of tooth paste.

Special compounds are available from automotive supply stores for the purpose of checking differential gear tooth patterns and contact. Use one of these for checking the bevel gears.

Assemble the front final gear case (see Front Final Gear

Case Assembly). Do not apply liquid gasket during adjustment.

Turn the pinion gear shaft for one revolution in the drive and reverse (coast) direction, while creating a drag on the ring gear.

Remove the ring gear and pinion gear unit to check the drive pattern and coast pattern of the bevel gear teeth.

The tooth contact patterns of both (drive and coast) sides should be centrally located between the top and bottom of the tooth. The drive pattern can be a little closer to the toe and the coast pattern can be a somewhat longer and closer to the toe.

If the tooth contact pattern is incorrect, replace the pinion gear shim(s), following the examples shown.

Then erase the tooth contact patterns and check them again. Also check the backlash every time the shim(s) are replaced. Repeat the shim change procedure as necessary.

NOTE

If the backlash is out of the standard range after changing the pinion gear shim(s), change the ring gear shim(s) to correct the backlash before checking the tooth contact pattern.

Bevel Gear Case (KAF400-A/C)

Bevel Gear Inspection

Visually check the drive bevel gear [A] and the driven bevel gear [B] for scoring, chipping, or other damage.

Replace the bevel gears as a set if either gear is damaged.

Ball Bearing/Oil Seal Inspection

Since the ball bearings are made to extremely close tolerances, the wear must be judged by feel rather than measurement. Clean each bearing in a high flash-point solvent, dry it (do not spin the bearing while it is dry), and oil it with engine oil.

Spin [A] the bearing by hand to check its condition.

If the bearing is noisy, does not spin smoothly, or has any rough spots, replace it.

Inspect the oil seals.

Replace it if the lips are misshapen, discolored (indicating that the rubber has deteriorated), hardened, or been otherwise damaged.

Brake Fluid

Brake Fluid Recommendation

Use extra heavy-duty brake fluid only from a container marked DOT3.

Recommended Brake Fluid

Type: DOT3

WARNING

Never reuse old brake fluid.

Do not use fluid from a container that has been left unsealed or that has been open for a long time.

Do not mix two types and brands of fluid for use in the brake. This lowers the brake fluid boiling point and could cause the brake to be ineffective. It may also cause the rubber brake parts to deteriorate.

Don’t leave the reservoir cap off for any length of time to avoid moisture contamination of the fluid.

Don’t add or change the fluid in the rain or when a strong wind is blowing.

If any of the brake line fittings or the bleed valve is opened at any time, the AIR MUST BE BLED FROM

THE BRAKE LINE.

CAUTION

Brake fluid quickly ruins painted surfaces; any spilled fluid should be completely wiped up immediately.

Brake Fluid Level Inspection

Refer to the Brakes in the Periodic Maintenance chapter.

Brake Fluid Change

Refer to the Brakes in the Periodic Maintenance chapter.

Brake Line Air Bleeding

Tilt up the front cargo hood.

Remove:

Rubber Cap

Brake Fluid Reservoir Cap

Level the reservoir [A] and check that there is plenty of fluid in the reservoir.

NOTE

The fluid level must be checked several times during the bleeding operation and replenished as necessary. If the fluid in the reservoir runs completely out any time during bleeding, the bleeding operation must be done over again from the beginning since air will have entered the line.

With the reservoir cap off, slowly pump the brake pedal several times until no air bubbles can be seen rising up through the fluid from the holes at the bottom of the reservoir. This bleeds the air from the master cylinder end of the line.

Property of www.SmallEngineDiscount.com - Not for Resale

Brake Fluid

Remove the wheel for extra clearance (see Wheels/Tires chapter).

Connect a clear plastic hose [A] to the bleed valve at the wheel cylinder, running the other end of the hose into a container.

[B] Brake Panel

NOTE

Start with the rear left or right wheel and finish with the front left or right wheel.

Bleed the brake line and the caliper as follows:

Repeat this operation until no more air can be seen coming out into the plastic hose.

1. Pump the brake pedal until it becomes hard, and apply the brake pedal and hold it.

2. Quickly open and close the bleed valve while holding the brake pedal applied.

3. Release the brake pedal.

Tighten:

Torque - Bleed Valves: 8.0 N·m (0.82 kgf·m, 71 in·lb)

Repeat the previous step for each wheel.

When air bleeding is finished, add fluid up to the upper level in the reservoir.

Apply the brake forcefully for a few seconds, and check for fluid leakage around the fittings.

Install the removed parts.

Wheel Cylinder Removal/Installation

Refer to Brake Wheel Cylinder Assembly Replacement in the Periodic Maintenance chapter.

Wheel Cylinder Assembly

Before assembly, clean all parts including the wheel cylinder with brake fluid or alcohol, and apply brake fluid to the removed parts and the inner wall of the cylinder.

CAUTION

Use only brake fluid, isopropyl alcohol, or ethyl alcohol for cleaning brake parts. Do not use any other fluid for cleaning these parts. Gasoline, motor oil, or any other petroleum distillate will cause deterioration of the rubber parts. Oil spilled on any part will be difficult to wash off completely, and will eventually deteriorate the rubber used in the brake.

Wheel Cylinder Inspection

Remove the wheel cylinder (see Brake Wheel Cylinder

Assembly Replacement in the Periodic Maintenance chapter).

Disassemble the wheel cylinder.

Check that there are no scratches, rust or pitting on the inside of the cylinder [A] and on the outside of the piston

If the cylinder or piston shows any damage, replace the wheel cylinder.

Inspect the cups [C].

If a cup is worn, damaged, softened (rotted) or swollen, replace the wheel cylinder.

If fluid leakage is noted at the dust seals, the wheel cylinder should be replaced to renew the cup.

Precautions

There are a number of important precautions that are musts when servicing electrical systems. Learn and observe all the rules below.

Do not reverse the battery lead connections. This will burn out the diodes in the electrical parts.

Always check battery condition before condemning other parts of an electrical system. A fully charged battery is a must for conducting accurate electrical system tests.

The electrical parts should never be struck sharply, as with a hammer, or allowed to fall on a hard surface. Such a shock to the parts can damage them.

To prevent damage to electrical parts, do not disconnect the battery leads or any other electrical connections when the main switch is on, or while the engine is running.

Because of the large amount of current, never keep the main switch turned to the start position when the starter motor will not turn over, or the current may burn out the starter motor windings.

Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground.

Troubles may involve one or in some cases all items.

Never replace a defective part without determining what

CAUSED the failure. If the failure was brought on by some other item or items, they too must be repaired or replaced, or the replacement part will soon fail again.

Make sure all connectors in the circuit are clean and tight, and examine wires for signs of burning, fraying, etc. Poor wires and bad connections will affect electrical system operation.

Measure coil and winding resistance when the part is cold

(at room temperature).

Electrical Wiring

Wiring Inspection

Visually inspect the wiring for signs of burning, fraying, etc.

If any wiring is poor, replace the damaged wiring.

Pull each connector [A] apart and inspect it for corrosion, dirt, and damage.

If the connector is corroded or dirty, clean it carefully. If it

• is damaged, replace it.

Check the wiring for continuity.

Use the wiring diagram to find the ends of the lead which is suspected of being a problem.

Measure the resistance between the ends of the leads.

If the resistance is not 0

Ω, the lead is defective. Replace the lead or the wiring harness if necessary.

16-18 ELECTRICAL SYSTEM

Battery

Initial Charging

WARNING

Keep the battery away from sparks and open flames during charging, since the battery gives off an explosive gas mixture of hydrogen and oxygen. When using a battery charger, connect the battery to the charger before turning on the charger. This procedure prevents sparks at the battery terminals which could ignite any battery gases.

CAUTION

If the battery is not given a full initial charging, it will discharge in a few weeks. After that it can not be charged by supplemental charging.

Always remove the battery from the vehicle for charging. If the battery is charged while still installed, battery electrolyte may spill and corrode the frame or other parts of the vehicle.

Do not use a high rate battery charger, as is typically employed at automotive service stations, unless the charger rate can be reduced to the level required.

Charging the battery at a rate higher than specified may ruin the battery. Charging at a high rate causes excess heat which can warp the plates and cause internal shorting. Higher-than-normal charging rates also cause the plates to shed active material. Deposits will accumulate, and can cause internal shorting

If the temperature of the electrolyte rises above

45°C (113°F) during charging, reduce the charging rate to lower the temperature, and increase charging time proportionately.

Remove:

Battery

Filler Caps

WARNING

Electrolyte contains sulfuric acid which is harmful to skin, eyes, and clothing.

Wear eye protection and rubber gloves.

If spillage occurs on body or clothing, rinse at once with water for at least 15 minutes.

Property of www.SmallEngineDiscount.com - Not for Resale

Battery

Fill each cell to the upper level line on the battery case with fresh electrolyte (specific gravity: 1.270) at a temperature of 30°C (86°F) or less. Let the battery stand for about 30 minutes before charging.

NOTE

If the electrolyte level drops, add electrolyte to the upper level line before charging.

Set the charging rate at 1/10 the battery capacity, and

charge it for 10 hours. For example, if the battery is rated at 14 Ah, the charging rate would be 1.4 Ah.

Turn the charger off, then disconnect it from the battery.

Check:

Electrolyte Level (see Electrolyte Level Inspection)

Tighten the filler caps.

Ordinary Charging

WARNING

Keep the battery away from sparks and open flames during charging, since the battery gives off an explosive gas mixture of hydrogen and oxygen. When using a battery charger, connect the battery to the charger before turning on the charger. This procedure prevents sparks at the battery terminals which could ignite any battery gases.

CAUTION

Always remove the battery from the vehicle for charging. If the battery is charged while still installed, battery electrolyte may spill and corrode the frame or other parts of the vehicle.

If the battery voltage suddenly jumps to over 13 V just after the start of charging, the plates are probably sulfated.

A good battery will rise to 12 V immediately and then gradually go up to 12.5 or 13 V in about 30 min. to an hour after the start of charging.

If one cell produces no gas bubbles or has a very low specific gravity, it is probably shorted.

If there does not appear to be enough sediment in a cell to short the plates, but that cell has a very low specific gravity after the battery is fully charged, the trouble may be that there is not enough acid in that one cell. In this case only, sulfuric acid solution may be added to correct the specific gravity.

If a fully charged battery not in loses its charge after 2 to 7 days; or if the specific gravity drops markedly, the battery is defective. The self-discharge rate of a good battery is only about 1% per day.

Charging System Operational Inspection

Check battery condition (see Charging Condition Inspection in the Periodic Maintenance chapter).

NOTE

Always check battery condition before condemning other parts of the charging system. The battery must be fully charged in order to conduct accurate charging system tests.

Warm up the engine to bring the components up to their normal operating temperatures.

Measure regulator/rectifier output voltage at various engine speeds with the headlights turned on and then turned off.

Connect a voltmeter across the battery terminals.

The readings should show nearly battery voltage when the engine speed is low, and as the engine speed rises, the readings should also rise. But they must stay within the specified range.

If the output voltage is much higher than the specification, the regulator/rectifier is defective, or the regulator/rectifier leads are loose or open.

If the output voltage does not rise as the engine speed increase then the regulator/rectifier is defective or the alternator output is insufficient for the loads.

Stator Coil Resistance

Disconnect the alternator leads connector.

Measure the stator coil resistance.

Connect an ohmmeter between the alternator leads.

Stator Coil Resistance

Standard: 0.3

Ω or less

If the meter does not read as specified, replace the alternator stator.

If the coil has normal resistance, but the voltage inspect showed the alternator to be defective; then the rotor magnets have probably weakened, and the rotor must be replaced.

Regulator/Rectifier Inspection

Remove the regulator/rectifier [A].

Rectifier Circuit Test

Check the resistance in both directions between the terminals following the table.

Tester Connection

W-G/W1, W-G/W2

BK/Y-G/W1, BK/Y-G/W2

The resistance should be low in one direction and more than ten times as much in the other direction. If any two terminals are low or high in both directions, the rectifier is defective and must be replaced.

NOTE

The actual meter reading varies with the meter used and the individual rectifier, but, generally speaking the lower reading should be from zero to the first 1/2 of the scale.

Connect the test light and the 12 V battery in the manner as specified in the "Regulator Circuit Test-1st Step."

Apply 12 V to BR terminal.

Check G/W1 and G/W2 terminals respectively.

If the test light turns on, the regulator/rectifier is defective.

Replace it.

If the test light does not turn on, continue the test.

ELECTRICAL SYSTEM 16-27

Regulator Circuit Test-3rd Step:

Connect the test light and the 12 V battery in the same manner as specified in the "Regulator Circuit Test-1st

Step."

Momentarily apply 24 V to BR terminal by adding a 12 V battery.

Check G/W1 and G/W2 terminals respectively.

CAUTION

Do not apply more than 24 V to the regulator/rectifier and do not leave the 24 V applied for more than a few seconds, or the unit will be damaged.

If the test light did not light when the 24 V was applied momentarily to the BR terminal, the regulator/rectifier is defective. Replace it.

If the regulator/rectifier passes all of the tests described, it may still be defective. If the charging system still does not work properly after checking all of the components and the battery, test the regulator/rectifier by replacing it with a known good unit.
