OILING SYSTEM TESTS
Cylinder Oil Pump Resistance
Test
Disconnect the battery cables at the battery.
Disconnect th e e lectrical connector f rom the oil
injection pump.
Use a digital multimeter to measure the resistance
between the pins of the oil pump conn ector. 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 re move any cont amination. Rein-
stall filter.
Carefully remove the oil hose from the oil pickup
and remove the oil supply h ose 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 o utboard side of oil
supply hose an d draw 7 in. Hg (24 kPa) va cuum

A WARNING
Wear safety glasse s to avoid personal
injury, and set compressed air pressure to
less than 25 psi (172 kPa).
