Please Help! Rear rim rebuild Bearing shim?

Post by tdboze » Sat May 20, 2017 2:33 pm

I am rebuilding the rear rim on a 65 CL72. It's an early model, of course. I am restoring the whole bike but right now I am reassembling the rear rim/hub. My question is this:
Is there a shim between the hub bearing 6303z and the brake housing? It appears that there should be to keep the brake housing (non rotating) from coming in contact with the(rotating) hub as the bearing is flush with the hub end. I can't find one (shim) in my pile of parts that were assigned to the rear rim/hub. Unfortunately, the hundreds of pics I took during disassembly do not include one of the brake cover inside. If pics would help I will try to post some. The parts diagram does not list one. Maybe there is something that I am not seeing at this point in the assembly that keeps these two parts from contacting each other?


Thanks!

Thanks for the reply. That looks about like what I'm thinking would be there, but for the 65 I haven't seen any reference to it. It looks like your diagram is for a later model with the double leading shoe brakes. The 65 has single leading shoe so there may be a difference. I will sort through my parts again and see if I run across anything. With the pieces assembled it appears the only point of contact without a shim is actually the inner race of the bearing, but I'm still skeptical though.

Looks like the front is the same way and I don't have a shim for that either, so maybe there's not supposed to be one.

Ahhh, the joy's of restoration by inexperience :)

The inner race of the bearing does not rotate so it is perfectly feasible for the brake plate to clamp up against the bearing inner race. The bearing is backed up by the distance between the two wheel bearings.

I just pulled this one apart for you. The raised area at the centre of the brake plate rests only on the inner race of the bearing.
