For cleaning, dismantle the pump as follows:
1. Remove the adjusting screw A.
2. Loosen locking screw B against which the cam curve of the pump drive runs.
Check the wear of screw B. If worn, the screw should be changed.
3. Knock the edge of the pump housing against a piece of wood to make the
pump piston slide out of the casing.
Assembly
Asssembly of the oil pump is made in reverse order to dismantling.
1. Check that the sealing ring (C) on the pressure side is fitted, clean and
undamaged.
Use sleeve No. 5025052-01 to protect the sealing ring when the pump is
fitted into the crankcase.
2. After fitting the pump into the crankcase, check that the pump piston turns
easily and that the return spring returns the pump drive towards the guide
screw.
