CHECKS AND OVERHAUL
Oil seal rings
Make sure the oil seals have not hardened round the internal
contact edge with the crankshaft and that they do not show signs of
cracks or wear. If they do, replace them with new ones of the same
size.
Then re-fitting the oil seal, use protective cone cod.
00365R0260. Fit said cone over the ends of the crankshaft
to avoid damage to the ring itself.
Tappet checking
Make sure the tappet surfaces are not worn, lined or present signs
of seizure. If so, replace.
