Oil Pump Bleeding
The oil pump must always be bled following any service to the injector system or engine which allows the loss
of oil and subsequent entrapped air during reassembly.
1. Fill oil reservoir with Polaris injector oil.
2. Loosen brass hex head screw (A). After a short time
oil should flow from beneath the screw head to
indicate the pump is free of air.
3. Tighten bleed bleed screw.
Oil Pump Adjustment - All Models
After the engine RPM and carburetor adjustments have
been made, the oil pump must also be adjusted.
1. With engine shut off and throttle in its idle position,
the pump lever index mark (A) must align with the
pump housing boss index mark (B).
2. Loosen lock nuts on cable housing sleeve and vary
cable housing length as required. NOTE: Verify
that pump lever is actuated upon initial throttle
opening.
Oil Pump Drive Gear End Play Adjustment
If the oil pump, crankcase, or any other oil pump drive
component is replaced, inspect the drive gear end play
using the following procedure:
1. Measure distance from oil pump mounting surface to
bushing. Call this measurement “A”.
NOTE: Make sure the bushing is fully seated in the
crankcase.
