Oil Pump
Oil Pump Bleeding
The oil pump must be bled following any repair service
to the injection system which might allow loss of oil and
subsequent trapped air upon reassembly.
IMPORTANT: Always pre-mix the first tank of fuel used
after oil pump or engine service to ensure proper lu
brication of the engine.
70 . Fill oil reservoir with Polaris injector oil.
71 . Loosen hex head screw at top of oil pump.
72 .After a short period of time oil should begin to flow
from beneath the screw head. Be sure that a
steady flow of oil is evident to remove all air before
tightening the screw.
73 .Tighten screw.
Do not over tighten. The screw is hollow.
74 . Any time the engine is disassembled or repaired it is
important that each oil supply line from the pump to
the engine be checked for signs of wear or air
bubbles. If air bubbles greater than 1/2" (1.3 cm) in
length are present, fill oil supply lines with oil using a
small oil squirt can.
Troubleshooting
NOTE: See Maintenance section for adjustment/in
spection information.
75 . Remove lines from their fittings at the engine and
pump. Blow through them to ensure they are not
plugged or restricted.
76 .Apply some pressure to the check valve fittings
with the Mity Vac™ or similar tool. These valves
should open with 2-5 lbs. of pressure.
77 . Be sure oil feed lines fit tightly, are not cracked or
leaking.
78 . Be sure the in-line filter between oil pump and oil
tank is clean and bleeding is complete.
79 . If oil still won't flow, replace the oil pump.
NOTE: This machine is equipped with a variable oil
pump controlled by a link rod between the carburetors
and the pump arm. This is a non-adjustable rod. It is
necessary to inspect the rod and linkage for correct
installation and smooth operation before running the
engine.
