Rammer Repair
General
2.1
Description
Rammers are designed to compact loose soils and gravel to prevent
settling and to provide a firm, solid base for the placement of footings,
concrete slabs, foundations, and other structures.
2.2
Power Transmission
BS 50, BS 60, BS70, BS 65, BS 500, BS 600, BS 700, and BS 650
Rammers are powered by the WACKER WM80 engine. The BS 50-4
and BS 60-4 Rammers are powered by the WACKER WM90 engine.
These gasoline engines are specifically designed for use on WACKER
Rammers.
The DS 720 and DS 70 Rammers are powered by a Yanmar diesel
engine, making it suitable for use in potentially explosive
environments.
The engine crankshaft turns a centrifugal clutch that allows the engine
to be disengaged from the ramming system during engine start-up and
idling.
The engine drives the ramming system through a set of reduction
gears and a connecting rod. The reduction gears and connecting rod
convert the engine’s circular motion (4250-4450 rpm) to the vertical
stroking motion (600-750 blows per minute) of the ramming system.
The gear reduction increases the available power to drive the ramming
system through each stroke. The connecting rod attached to the crank
gear converts the circular rotation of the gears to the up and down
stroking motion of the rammer.
2.3
Spring System
The spring system consists of a piston between two spring sets. The
piston is connected to the ram that is driven by the connecting rod
attached to the crank gear. Plastic bushings on either side of the piston
prevent the springs from bottoming out. The piston and spring sets are
housed in the spring cylinder that slides up and down inside the guide
cylinder.
The spring system has two functions. The spring system’s first function
is to store energy created by the engine and release it to the shoe
during its downward stroke. The spring system’s second function is to
isolate the shock that is created when the ramming shoe hits and
prevent it from being transmitted back to the rammer.
wc_tx000284gb.fm

Rammer Repair
2.4
General
Bellows
The bellows provides a flexible joint between the ramming system and
the upper machinery. It seals out dust and dirt and provides a clean
path for recirculating oil.
2.5
Lubricating System
The rammers use a sealed-oil-bath lubricating system. Oil is
distributed to the gears, the bearings, the springs, and the other
moving parts by the up and down action of the ramming system. The
ramming system carries the oil into the crankcase through holes drilled
in the spring system piston and the spring cylinder.
2.6
Threadlocking Compounds
Due to the heavy vibration inherent in this type of equipment, the repair
and service procedures described in this manual specify the use of
threadlocking compounds. These compounds should be used where
indicated to prevent the fasteners from becoming loose.
Although Loctite® is referred to throughout this manual, any equivalent
type of sealant such as Hernon, Prolock, or Omnifit may be used.
Clean the screw threads and wipe off any oil or grease before applying
a threadlocking compound.
For a complete list of recommended sealing and locking compounds,
refer to the Use of Threadlockers and Sealants chart at the end of this
Repair Manual.
2.7
Torque Values
The torque values for the referenced fasteners are detailed in the
repair procedures. For a complete list of the recommended torque
values, refer to the Torque Values chart at the end of this Repair
Manual or in the Rammer Parts Book.

The Tillotson carburetor uses a fixed low and high speed fuel jet. The
only adjustment is to set the engine idle speed.
Refer to section Technical Data for the correct idle and operating rpm.
For best accuracy, use a tachometer when making carburetor
adjustments.
NOTICE: The engine is lubricated by the fuel mixture; running the
engine too lean could cause it to overheat.
High Altitude Operation
The WM 80 engine used in the rammers is designed to operate most
efficiently at normal altitudes (1524 meters) (up to 5000 ft.). At high
altitudes (1524 meters) (above 5000 ft.) minor modifications to the
carburetor can be made to improve its performance. All modifications
must be performed by an authorized WACKER dealer. Contact
WACKER Corporation for more information.
High altitude operations involve modifications to the engine air/fuel
mixture. At normal altitudes, these modifications can be damaging to
the engine components. When returning the rammer to normal altitude
operation, remember to reset the carburetor to its standard
specifications.
Setting Idle Speed Adjustment
3.8.1
Start the engine and allow it to warm up to operating temperature.
3.8.2
Set the engine idle speed with the engine running at idle and the choke
(a) fully open. Adjust the idle speed screw (b) in or out to obtain the
correct idle speed.

Check oil level:
Tilt the machine backwards approximately 15° until the engine is level
by placing a wedge under the shoe. The oil surface should reach NO
HIGHER THAN the bottom of the filler neck “H”, but no lower than “L”
(see drawing) or visible on the dipstick (a) when it is inserted (not
screwed) into the filler neck.
Add CC or better quality oil through the filler neck as required.
CAUTION: DO NOT overfill. The oil level should just reach the bottom
of the filler neck. Too much oil can cause damage to the engine and
the rammer.
Note: After transporting the rammer horizontally, upright the rammer
and allow the oil to drain back through the engine. It may take up to 45
minutes for the oil level to recover.

Inspecting the Spring System
See Graphic: wc_gr001329rm
Over time, the constant compression and release of the spring
pressure can cause the springs to wear out. If the rammer feels to be
hitting with less force, it is possible that the springs are worn and
should be replaced.
A broken spring causes the rammer to jump erratically. This condition
is more noticeable on hard soils. Do not run the rammer if a broken
spring is suspected. Doing so may damage other rammer parts.
Replace both the top and the bottom spring sets even if only one set is
worn or damaged.
4.5.1
Remove the springs from the cylinder and check them for minimum
spring free height and maximum spring height difference per the table
below. Replace the springs if they do not meet the given specifications.
4.5.2
If a spring has broken, inspect the inside of the spring cylinder wall for
burrs, gouges, and cracks as follows:
•
Slide the piston guide inside the cylinder. Check that the piston
guide moves freely but without excessive side play.
•
Hone the cylinder to remove the ridges and the burrs that were
cut into the cylinder wall by the spring movement.
•
Replace the cylinder if it is badly worn.

Oil for lubrication is carried throughout the ramming system by the
action of the rammer. Holes drilled in the piston allow the oil to be
distributed from the bottom of the rammer to the crankcase. Oil in the
ramming system must be maintained at the correct level to ensure the
system operates efficiently.
Check oil level:
Check the oil level in the sightglass (a) daily before starting the
rammer. When checking the oil, make sure the rammer is on a flat,
level surface. The oil level should fill 1/2–3/4 of the sightglass. Add the
oil though the fill plug (c) located in the filter housing at the top of the
rammer. See section Technical Data for oil quantity and type.
Change the ramming system oil after the first 50 hours of operation
and then after every 300 hours of use.
Oil change:
4.7.1
Remove the oil fill plug (c) and the seal ring.
4.7.2
BS 500: Remove the sightglass.
BS 600/700/650, DS720: Remove the drain plug (b).
4.7.3
Tilt the rammer back until it is resting on its handle.
4.7.4
Allow the oil to drain.
4.7.5
Wrap the sightglass threads with Teflon tape.
4.7.6
Reinstall the sightglass or the drain plug, and torque to 9.5 Nm (7

4.7.7
Stand the rammer upright on a level surface.
4.7.8
Add oil through the fill plug. Proper ramming system lubrication is
indicated when approximately 1/2–3/4 of the sightglass is full.
NOTICE: It may take some time for the oil to filter down to the
sightglass. Use care not to overfill the ramming system. Excessively
high levels of oil can create a hydraulic lock in the ramming system.
This can result in erratic operation and cause damage to the engine
clutch, the ramming system, and the shoe.

Float Switch Testing and Replacement
See Graphic: wc_gr001526
NOTICE: Never bypass the float switch except during testing; engine
failure may occur.
The function of the float switch is to prevent the engine from running
without oil in the oil tank. If the oil tank is low on oil, the float switch
opens and kills the ignition. A severed float switch wire will also kill the
ignition.
In the event that the engine runs but shuts off by itself within
approximately 25 seconds, even with oil in the oil tank, the float switch
could be faulty.
To test the float switch (a):
6.1.1
Remove the carburetor guard (d).
6.1.2
Inspect the float switch wire for damage.
•
If damage is present, replace the float switch.
•
If no damage to the float switch wire is obvious and the connector
is fully seated at the engine (b), continue.
6.1.3
Unplug the float switch wire from the engine.
6.1.4
Insert a jumper wire into the terminal on the engine to connect the two
terminal leads.
6.1.5
Start the engine and run it at idle.
•
If the engine continues to run for more than 45 seconds, the float
switch is faulty and must be replaced.
•
If the engine still shuts off within 25 seconds, the ignition module
has failed and must be replaced.
To replace the float switch:
6.1.6
Drain the remaining oil from the oil tank or position the rammer so that
the oil in the tank will not run out when the float switch is removed.
6.1.7
Remove the oil line from the float switch.
6.1.8
Disconnect the float switch from the back of the engine.
6.1.9
Unscrew the float switch assembly from the oil tank.
6.1.10 Screw a new float switch assembly into the oil tank.
6.1.11 Install the oil line to the float switch. Ensure that the oil line from the oil
tank is routed through the coiled portion (c) of the float switch wire near
the switch.

The the function of the oil line check valve (a) is to prevent raw fuel
from backing up to the oil pump. It is important that the check valve be
installed in the correct direction. Looking at the side of the check valve,
one should notice recessed areas with pointed ends or an arrow (b).
The pointed ends or the arrow must point towards the fuel line. This is
the direction of oil flow.
To test the check valve:
The oil line check valve is spring operated and is designed to release
at 1.5 psi. Note: Initial release can be as high as 4.5 psi.
6.2.1
Remove the oil line check valve from the oil line.
6.2.2
Attach a hand-operated vacuum pump to the outlet side (pointed end)
of the oil line check valve and operate the vacuum pump until the
vacuum overcomes the oil line check valve spring. Measure how much
vacuum it takes to operate the oil line check valve. A vacuum reading
of more than 2 psi (after initial release) is grounds for replacing the oil
line check valve.
Note: The oil line check valve is only available by replacing the entire
hose assembly.
Newly installed oil line check valves (and those that have lost their
prime) require priming. There are two methods of priming the oil line
check valve line with oil.
Vacuum method:
6.2.3
Attach a hand-operated vacuum pump to the fuel line end of the oil
hose.
6.2.4
Place the oil pump side of the hose in a container of 2-cycle oil.
6.2.5
Operate the vacuum pump until the oil reaches the vacuum pump.
6.2.6
Install the oil line to the oil pump and to the fuel line.
Pressure method:
6.2.7
Attach a syringe filled with 2-cycle oil to the oil pump end of the hose.
6.2.8
Inject the oil into the hose until it passes through the oil line check
valve.
6.2.9
Attach the oil line to the oil pump.
NOTICE: The oil line check valve is an important part of the oil injection
system and should not be bypassed. Engine failure may occur.

Oil Pump / Cartridge Assembly
See Graphic: wc_gr001528
If the rammer was used for a long period of time, it does not appear to
have used any oil, and the oil line check valve is operating correctly,
remove and check the oil pump. Keep in mind that oil-injection
rammers can run up to 65 hours on one tank of oil.
Removal:
6.3.1
Remove the engine and the carburetor guard.
6.3.2
Remove the output hose only (a) from the oil pump.
6.3.3
Remove the three screws holding the oil pump/cartridge assembly to
the rammer crankcase.
6.3.4
Remove the oil pump and the cartridge assembly from the crankcase.
6.3.5
Separate the oil pump from the cartridge assembly. Inspect the plastic
gear on the cartridge assembly for damage. If the plastic gear is
damaged, replace it.
Testing:
Ensure that the oil tank is full of oil and that the oil line from the tank to
the pump is not kinked or loose.
6.3.6
Open the bleed screw on the front of the pump until oil flows out.
Tighten the bleed screw.
6.3.7
With the gear side of the pump facing you, and the gear on the top,
rotate the gear clockwise (when viewed from left side). Oil should flow
out of the output fitting in less than 20 revolutions of the gear (keep in
mind that the pump puts out a 0.8 mm (0.030 in.) droplet of oil every
7–9 seconds of running at 4350 rpm). If no oil comes out of the output
fitting, replace the pump.

Testing the Low Oil Unit
See Graphic: wc_gr003673
The function of the low oil unit is to prevent the engine from running
after startup if the engine is low on oil.
To test the low oil unit:
7.1.1
Remove the lower engine guard (a).
7.1.2
Lay the machine down and remove the low oil unit (b) from the
crankcase.
7.1.3
Disconnect the wiring from the engine to the low oil unit.
7.1.4
Attach a 9V battery to the low oil unit as shown. A functioning low oil
unit should flash at a steady rate.
7.1.5
•
If the low oil unit does not flash at a steady rate, it has failed;
replace it.
•
If the low oil unit does flash at a steady rate, continue.
Grasp the sensors (c) with your fingertips. This action will change the
capacitance of the sensors, and will change the flashing action (duty
cycle) of the low oil unit from a period where the light remains on longer
than it is off, to one where the light is off longer than it is on.
•
If the low oil unit performs accordingly, it is functioning properly.
•
If the low oil unit does not perform accordingly, it has failed;
replace it.

Threadlockers and Sealants
Threadlockers and Sealants
Threadlocking adhesives and sealants are specified throughout this
manual by a notation of “S” plus a number (S#) and should be used
where indicated. Threadlocking compounds normally break down at
temperatures above 175°C (350°F). If a screw or bolt is hard to
remove, heat it using a small propane torch to break down the sealant.
When applying sealants, follow instructions on container. The sealants
listed are recommended for use on Wacker equipment.
