OIL PUMP PRIMING
PROCEDURE
NOTE: This priming procedure must be
performed whenever the oil hose connection
between the oil tank and pump inlet has been
disconnected.
1. Clamp or pinch off vent line (A) approximately 2
I
from oil tank to avoid the end of oil tank vent fitting,
and the vent line’s pressure relief slit
2. Run engine at idle for 10--20 seconds.
3. Shut engine off. Remove the vent line clamp. A
rush of air should be heard, indicating the oil pump
is properly primed and ready for field operation.
Note: If the system is primed properly you should
hear some air release. If you do not, the system
has not primed. Repeat the process if necessary.
