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.
