GENERAL INFORMATION AND SAFETY SUMMARY
As we will have no influence on the installation of complete windscreen wiper systems if installation
is to be carried out by the customer, we are unable to accept liability for installation errors.
If you require any additional information or any special problems arise which the
installation/maintenance instructions do not treat in sufficient detail please contact Customer
Service at B. Hepworth and Co Ltd directly.
Safety Precautions
CAUTION! BEWARE OF INJURY!
BEFORE WORKING ON THE WIPER SYSTEM, OBSERVE THE FOLLOWING REMARKS
WITHOUT FAIL!
Most wiper motors have a park setting, which permits them to default to the parked position if
connected to the vehicle electrical system, even when the wiper is switched off. FOR THIS
REASON, AT THIS POINT IN TIME, NEITHER MAY THE WIPER ARM BE MOUNTED, NOR MAY
ANY PERSON HAVE HANDS, FINGERS, ETC ANYWHERE NEAR THE WIPER SYSTEM. Even
small wiper motors can neither be braked nor stopped by hand.
NEVER REACH INTO THE AREA OF THE ROD LINKAGE WHEN THE SYSTEM IS RUNNING!
When putting into service (i.e. when connecting the wiper motor to the vehicle electrical system,
even if the wiper switch is in the 0 position), never leave any loose items such as screwdrivers in
the area of the wiper system, as flying objects could lead to injury.
Please ensure the equipment is handled with care. Do not drop or bang the equipment down on a
hard surface taking extra care around the area where the motor shaft is situated. Do not hammer
the motor shaft when installing the equipment, as this will cause the motor gear plate to deform
causing premature failure of the unit.
Introduction
The Windscreen Wiper system utilised is detailed on the following pages. The primary components
that form the Windscreen Wiper System are the wiper motor linkage, the wiper arm assemblies
and the wiper blades.
Vari-Arc Lever Settings
IMPORTANT
Vari-arc levers which have been factory set will be torqued and paint marked. Do not adjust.
Unpainted lever nuts must be torque tightened M8 = 20Nm, prior to the unit being fitted.
Where internal fixing screws and/or nuts are factory set and paint marked, leave untouched unless
required to be changed or paint mark is damaged.

DESCRIPTION OF WIPER SYSTEM
Wiper Motor Assembly
The entire wiper motor/mounting bracket/linkage is mounted internally. The electric wiper motor
forms the central part of the windshield wiper system. The wiper motor is mounted on a fabricated
steel bracket which is polyester powder coated to prevent corrosion. The motor is connected
electrically by means of a multi-pin connector.
The drive crank is secured to the wiper motor shaft and connected through a double bearing or a
tie-bar/bearing assembly, to the main spindle lever assembly. These components transfer the
motor shaft rotation to the wiper arm assembly.
The drive mechanism transfers the rotary output from the motor to a reciprocating motion of the
spindles. This mechanism is zinc plated and is sized to give the correct angle of arc for the
windscreen wiper arm being driven.
A single main spindle only is used on pendulum units. This passes through the bulkhead,
connecting the drive mechanism to the wiper arm. This is manufactured from stainless steel, to
prevent corrosion.
An idler spindle is used on pantograph units. This is mounted on an external plate, connecting
directly to the wiper arm. The spindle is manufactured from stainless steel, to prevent corrosion.
Wiper Arm Assembly
The wiper arm is manufactured from stainless steel with brass castings and is polyester powder
coated to prevent corrosion and to be of good appearance.
One wiper arm assembly is used on each unit. The wiper arm assembly mounts directly onto the
spindles protruding through the bulkhead.
The wiper arm is secured to the spindles with a series of nuts and washers.
NOTE
In some applications the arm may have a forward and/or sideways crank to aid wiping.
Wiper Blade
The blade is secured to the arm assembly using the blade clip arrangement on the arm with a
blade retaining screw and nylock nut.

FITTING THE WIPER ARM ASSEMBLY
IMPORTANT:
The blade must be fitted to arm prior to arm being fitted. (This is to prevent blade clip
damaging screen)
Following applies to all styles of arm
1.
Internally - Run motor to insure it is parked correctly. Disconnect all electrical power.
2.
Externally - While unit is being run, it is IMPORTANT to observe direction drive spindle
rotates in immediately before it stops. This direction will give PARK POSITION.
3.
Fit arm onto spindle allowing blade to lie approx 50-75mm from edge of glass in PARKED
POSITION. Test on a wet screen to prove clearance is acceptable.
Ref Figure - Arm Fittings
4.
Fit one 8mm flat washer (14) on to spindle next to arm
head, then one M8 nylock nut (15), on to each spindle.
Figure - Arm Fittings

5.
Only tighten nut sufficiently to allow arm and blade to travel
across glass when motor is run to see if positioning is
correct.

6.
If incorrectly positioned - DO NOT ATTEMPT TO ROTATE
OR TWIST ARM ON SPINDLE this will damage splined
end of drive spindle, resulting in arm and blade slipping in
operation.

TROUBLESHOOTING
Introduction
The following provides all the instructions and information necessary to locate problems and
conduct tests on the windscreen wiper system components. The trouble-shooting tables provide for
logical isolation of faults.
Safety Precautions
Always disconnect the power when servicing the Windscreen Wiper System, or on any ancillary
components. Serious damage to the Equipment and/or Personal Injury may occur if the power is
not disconnected.
Troubleshooting Procedures
Typical windshield wiper system troubleshooting procedures are contained in the Tables. These
troubleshooting and repair procedures should be followed when encountering operational problems
with the windshield wiper system.

INSPECTION / MAINTENANCE - TABLES
Introduction
This chapter contains daily inspection and all preventative maintenance details for the windscreen
wiper components. Preventative maintenance procedures include the information required for
when to replace the wiper blades.
IMPORTANT
Refer to Maintenance Instructions for removal and replacement for procedures.
Safety Precautions
Always disconnect the power when servicing the Windscreen Wiper System, or on any ancillary
components. Serious damage to the Equipment and/or Personal Injury may occur if the power is
not disconnected.
Scheduled Maintenance Action Check
WARNING:
Isolate the electrical supply before commencing any fitting work on any
part of the wiper system.
The Inspection and Maintenance Tables are a Scheduled Maintenance Action Index. The index
provides a list of all performance tests if applicable and preventative maintenance procedures.
The tables have three columns: Periodicity, Equipment and Task
The Periodicity column indicates the intervals between the maintenance tests and preventative
maintenance procedures.
The equipment column lists the equipment, assembly or subassembly that corresponds to the
maintenance action.
The task column lists the maintenance task to be performed.
