Rear Hub Assembly
« on: October 19, 2014, 04:50:10 PM »
1972 CB500 - While assembling the rear hub, I had a bit of difficulty installing the drive flange (the part with the studs pictured below).  I had to use a rubber mallet to install and I do not remember it coming apart with any amount of force.  Should it fit this tight?  I would like to figure this out before I move on.

Thanks, Jim

The best way to put it on is to fit the sprocket, put the wheel on the ground with hub facing up, align the hub, wriggle it in side to side then stand on each side of the sprocket and keep alternating your weight from left foot to right, it should go on pretty easy.

Thanks but as you can see, I already have it assembled - just a little concerned that it went together so tight.  Also, the spacer is flush with the sprocket cover.  Hmm, this does not seem right (see picture below).

How do you get the hub to shine like that? Just curious.

It is ceramic coating.

It's going in rubber, so if no lube was used it will be tight, also can go in more than one way, sometimes pulling out, spin and try again, Bill. If its flush , same gap all around, you should be fine! New is also tighter fit.

It is also very possible that your power coater got ceramic on the edges of the hub and sprocket carrier. Ceramic is thicker than standard powder coat (I have the exact coating on my hubs and other parts too) and it is sufficient to create friction for assembly.

Double check the edges carefully. If "contaminated" then carefully sand it down a wee bit with 320-400 grit until it's a smooth fit.

Thanks fellas!!!!!  I'm not sure who to give the prize to.  I did some sanding on the friction surfaces.  I also added some white grease to the rubber.  What made all the difference is when I added a little white grease to the leading edge of the drive flange, where it meets the hub o-ring.  On it went by hand - no hammering.  Yeah!

Damn, I was hoping I could get my hubs to look like that with just polish
