Oil Pump Bleeding
CAUTION
If the oil supply line has been disconnected from the pump, or if
the oil reservoir and supply line have been completely run out of
oil, the oil pump must be bled. If the pump is not bled, air in the
lines may prevent oil delivery to the engine, resulting in severe
engine damage.
1. Fill the oil tank with the
recommended oil. See page 106 for
the part numbers of Polaris
products.
2. Loosen the bleeder screw one full
turn. Allow oil to flow from the
bleed screw for five to ten seconds,
then tighten the bleed screw.
CAUTION
Allowing the engine to run while the bleed screw is loose will
result in loss of oil, which will cause serious engine damage.
Always retighten the bleed screw if it’ s been loosened for service.
3. Start the engine and rotate the oil pump lever (2) to its full open
position. With the engine at idle, hold t he lever up for thirty
seconds to purge all air from the system.
