Motorcycle Repair/CA 77 Engine part


Hello.  Was doing a quick clean of my 1965 ca77 motor when I found this in the tub.  Both side cases were off.  I know that its not the clutch oil guide.  Can you help?   Thanks  Tom

Tom, the part is the small guide pin that goes on the end of the oil filter shaft, next to the thrust washer. It keeps the shaft from turning and must be installed so that it fits in the recess in the outer oil filter cover.

Need help with vintage Hondas from the 1960s? I am an expert with 250-305cc bikes in particular and most all of the other pre-91 models, in general. I do NOT claim to have a great deal of experience on Gold Wings, Cruisers, ATC/ATVs and dirt bikes.


I have owned/ridden/maintained Honda motorcycles for 35 years. I have written five books on Honda repairs and collecting. I was a service manager for two Honda shops back in the 1980s.
