Posting here on behalf of a few of my students, who are having some concerns regarding the Single Speed West Coast Drive gearbox from West Coast Products. They’ve gone ahead and done a dry assemble of the gearboxes and have noticed that the output shaft construction is not actually held down in any way, resulting in the whole shaft, plus bearings, popping out very easily.
Any suggestions? We could always secure the bearings into the plates ourselves, but given that the instructions even mention when to include the grease but don’t mention Locktite or glue, I wonder if maybe this isn’t how it’s supposed to go?
Note if you want to flip the bearing, you will need an extra spacer between the 1/2 inch bearing and the gear. We did that this year, and I believe it was an extra 1/16th needed, but it might have been 1/8th. You’ll have to check.
R.C, it would definitely be cool if next year it had bearing mount holes in the same location as the shifters. That was the one problem we had with our custom shifters that used the 3 CIM SS plates, and if those bearing holes were there from the start it would make things so much easier.
