Crankshaft rear oil-seal journal

If wear grooves can be felt with a finger nail, its not a bad idea to try to remove any edges by polishing, to prevent the oil-seal lip being damaged during installation. Ensure roundness is not compromised. Brasso or a very fine (500 ~ 800 grit) wet and dry used carefully.

Alternatively, when installing the seal in is housing, it can be sometimes be fitted in a slighly different position such that the lip sits on a fresh part of the journal. Lube well prior to installing the housing.
