OIL PUMP ADJUSTMENT PROCEDURE
1. Before adjusting the oil pump, check engine idle
RPM and set to specification. Adjust if necessary.
2. Check and adjust throttle lever free play (ETC
switch).
3. Apply parking brake.
4. Remove fan shroud.
5. Start the engine and let it idle.
CAUTION:
Keep away from moving fan.
6. Place very slight pressure on the throttle lever until
all freeplay is removed from throttle cable to
carburetor (to the point where the carb slide is just
starting to rise and engine RPM begins to
increase).
7. Expose oil pump adjuster. Loosen lock nut and turn
adjuster in or out until all freeplay is removed from
oil pump cable (the point where the oil pump arm is
just starting to move off of its stop).
NOTE: The pump stop keeps the pump arm from rotat-
ing any farther down than the idle position so no visual
alignment of marks is necessary.
8. Replace oil pump adjuster covers.
OIL PUMP BLEEDING PROCEDURE
1. Fill the oil reservoir with Polaris injector oil.
2. Loosen the pump bleed screw one full turn. Allow
oil to flow from the bleed screw for five to ten
seconds. Tighten bleed screw. CAUTION: Never
run the engine with the bleed screw loose. Loss of
oil will cause serious engine damage.
3. Start the engine and turn the oil pump lever or reel
to its full up (open) position. Allow engine to idle
with the lever in this position for ten to twenty
seconds to make sure all air is out of the system.
