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.
