Preparations:
– Take off the timing case cover; see M
11.00.
Dismantling:
– Take out the machine screws (97/1) and
lift off the oil pump.
– If necessary, pull out needle roller bea-
ring (98/1) with an internal puller.
Checking / repairs:
– Examine the contact face for the shaft
sealing ring for score-marks.
If the contact face is worn, a „wear
sleeve“ can be pushed over it. Use sea-
lant E for this purpose.
Installation instructions are included with
the spare part.

– Using a plastic-faced hammer, drive the
needle roller bearing flush into the
crankcase.

into the needle roller bearing and place
it over the centering sleeves.
– Insert and tighten the machine screws.
Note:
– Apply sealant D to the machine screw
for hole (98/2).
– Coat the endface of the oil pump which
is in contact with the crankcase with
sealant B.
– Re-assemble the engine in the reverse
order for dismantling.
– When renewing the oil pump, make sure
that the correct type is installed (2- / 3-
or 4-cylinder engine).
