Oil Pump Adjustment Procedure - Polaris Trail Blazer Service Manual

Oil Pump Adjustment Procedure

250cc / 300cc Engines
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. Place gear selector in neutral and apply parking
brake.
4. Start the engine and let it idle.
5. 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).
6. Loosen locknut (A).
7. Turn adjuster (B) in or out until all freeplay is
removed from oil pump cable (the point where the
oil pump arm (C) 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. Tighten the locknut.
