Fit the oil expansion plug (10), driving it home with
a suitable pin punch, after having checked that the
oilways are not blocked by blowing them through
with compressed air.
Make sure that the oil pump housing is free from
scoring and signs of seizure.
Fit the oil pressure relief valve (11).
N.B. Make sure that the number and thickness of wa-
shers (12x18x1, 12x18x1.5) for the oil pressure relief
valve are the same as in the factory setup.
Fit the crankshaft oilseal (12), lubricating its outer
surface with grease to make it easier to insert it into
its housing. Press it in until it is flush, with the open
side facing inwards.
N.B. Remember to always grease the outer surface of
oilseals to help seat them properly in their housings.
