OILING SYSTEM TESTS
Cylinder Oil Pump Resistance
Test
Disconnect the battery cables at the battery.
Disconnect the electrical connector from the oil
injection pump.
Use a digital multimeter to measure the resistance
between the pins of the oil pump connector. Cali-
brate the meter to the LOW OHMS scale.
Results:
An infinite reading (
) indicates an open circuit of
the injection pump winding. Replace faulty pump.
Oil Supply Vacuum Test
Remove the oil pick-up assembly from the oil tank.
Carefully remove the pickup filter and flush with a
mild solvent to remove any contamination. Rein-
stall filter.
Carefully remove the oil hose from the oil pickup
and remove the oil supply hose from the oil injec-
tion pump.
Use low pressure air to purge oil from hose.
Use Plug/Holder, P/N 329661, and clamp to plug
the pickup end of the hose.
Attach a vacuum tester to the outboard side of oil
supply hose and draw 7 in. Hg (24 kPa) vacuum
Oil Injection Pump Resistance

1. Oil injection pump connector 008446
WARNING
Wear safety glasses to avoid personal
injury, and set compressed air pressure to
less than 25 psi (172 kPa).
