Well

I hate how dirty this area gets

The bearing still has oil residue on it★
Time to swap it out for a double-sided seal! This way the grease inside lasts as long as possible.
No “C” specification required.

I originally planned to finish the rear maintenance too,
but the conversation ran so long we only got to the rear wheel

Grease coming loose and brown discoloration

The oil seal needs replacing too★
Spinning it in this condition creates super friction!
The steel collar wears down and creates contact marks, so I’ll lightly skim the seal with a stone rotary tool.
As for how much effect that has, I’d say it’s more of a “peace of mind” level.

It fits by hand, so there’s no need to tap it in
Adding grease inside the lip should make it feel a bit smoother.

Chain adjusters cost just a few hundred yen, so we swap them out from stock★
More tomorrow!
