ENGINE
When you inspect the oil pump you can check several points.
1. Is the oil pump leaking (1)?
2. Does the oil pump work properly?
1. Does the oil pump leak (1)?
Check the gaskets on the oil pump shaft. If the gaskets are dam-
aged or worn replace the oil pump.
2. Does the oil pump work properly ?
To test the proper function of the oil pump, the oil pump must be
mounted.
1. Remove the oil line (2) from the carburettor.
2. Start the vehicle and open the throttle ~ 80%.
3. After ~ 5 sec. a drop of oil must emerge.
4. Average flow is ~ 1 drop of oil/ 5 - 10 sec. in idle speed.
Let the engine work max. 30 sec. without lubrication.
A) When oil appear wipe away the first drop of oil and repeat the
process to make sure that the pump works proper.
B) If there no oil appear please check below points.
Bleed the oil pump ?
NOTE
To bleed the oil pump it is not necessary to start the engine. The
oil flows automatically due to gravity.
1. Open the bleed screw (3) until only oil flows from the pump.
There must be no air present.
2. Next, check whether the oil pump works proper. If not we
recommend to bleed the oil system as described in the next
step.
Bleed the oil system ?
1. Remove the oil tube also from the oil tank and refill the sys-
tem from the top with fresh oil.
2. For this use a one way syringe or similar. The system must be
refilled in the direction from the oil tank.
3. When the system is refilled correct connect the oil tube to the
oil tank and do the above test once again.
4. If everything is fine you can reassemble all parts.
