Hey All,
Thanks for the Welcome.
The bushing is the oil impregnated type. I didn't see a lot of wear but it built up a film on it and the mainshaft and would get sticky and gummed up. After replacing the clutch twice and cleaning the bush I finally got smart and replaced the bush, cured my problem of not wanting to disengage. This was on a stock 52, I replaced it with oem and size.
