A customer brought in a Racing Zero for service.


The right endcap on the rear hub, which has reverse threads,
had come loose by hand as usual.
Since this is where the center gauge contacts,
I've picked up the habit of checking it first.


↑While I had the freebody out,
I found one pawl that wasn't engaging.


I thought the spring might be bent,
but there's no real issue.
The viscosity of the grease had become so dirty and thick
that the pawl was essentially staying flat.


I cleaned everything and reassembled.
The marks from the hub-side ratchet knurling on the freebody
are there because the right end nut had been loose while riding.
As long as the right end nut is tightened properly, there's no real problem.


The customer initially wanted me to make the freewheel quieter,
but after discussing the pros and cons, they decided they wanted it loud instead.
It's really a matter of preference, so quiet isn't necessarily bad.

I cleaned the sprocket while I was at it.

Both front and rear wheels had enough runout to cause play with the center gauge,
but I got those straightened out.
