While replacing the clutch in my 1992 Acty, I decided I should also replace the pilot bearing. I was able to find a new one locally at an auto parts store. It is a 6001RU bearing. The one I bought was an NTN brand and it cost me approx $16.00. The place I went to also had some Chinese bearings for alot less, but I wanted either a US or Japanese made bearing.
