Comstar reassembly and part identification help

[ArBrnSnpr]

Hello all, I have a bit of a situation that I'm hoping someone here can help out with.

I have a Comstar wheel off a 1981 CB750F that was taken apart for powder coating and now seems to be missing parts.

Back story:

I dropped the wheel at a local shop to be powder coated and the shop doing the coating said it would be no issue. Well, they took the wheel to a local motorcycle shop to pull the bearings because they didn't know how. When I get my wheels back all nice and coated I realized the shop did not reassemble them. The shop gave me a box with the parts in it to do myself and unfortunately there seems to be a few parts missing.

I don't mind assembling the wheels and I would rather not deal with either of these shops (takes WAY too long) if I don't have to.

My issue is I'm missing the brass colored ring that sits in the front wheel that interfaces with the speedometer gear. I also don't know what it's called to begin trying to look the part up so I can replace it.

I'm hoping someone can help identify the proper name of the part I described so I can get it and get these wheels back together.

Thanks!

Further: I have searched, and I tried looking up exploded parts diagrams but none of the diagrams I found had parts lists attached. I did find one British site that had the part but called it a gear box retaining ring and that didn't seem to mesh with anything I could in US stores.

Thanks!

After looking through the items I got back from the shop I realized they also didn't give me back the bearing retaining cups or the center spacer/sleeve for the rear wheel. In fact, about all they did give me was the dampers for the rear wheel.

For the rear wheel, besides the bearing retainer caps and the sleeve are there any other parts I should have?

I decided to go back to the shop with a list of missing parts and request they be replaced.

In my Powder Coating business I do not claim to be a mechanic (even though I am). It is the customers responsibility to bring me the "the wheel", not the wheel assembled with greasy parts. I would charge you at least $50 to disassemble and I'm not responsible for anything that happens to the parts.
You don't need to disassemble a Comstar to coat them.

If that would have been the agreement then I would have taken care of it.

I specifically asked if the shop could disassemble the wheel and they said they could. Once accepting the task of disassembling the wheels, the responsibility to return all parts of the wheel became the shops - not mine.

No argument there. Who was the shop that did it?
And to elaborate on reassembly, I would refuse reassembly unless you supplied me with new bearing and seals. I will NEVER reassemble a customers item with used wearables. If you want to reuse the bearings and seals, you put it together.

I'm going to hold off on giving the details about the shop until I see how the situation resolves itself. I figure I might as well give them the chance to do right.

Also, I had every intention of putting new bearings in, but the shop claimed they were fine to reinstall. I've been twisting wrenches for years on cars and bikes but I've never handled or dealt with a set of comstars so I had no idea what went into it taking the bearings out or putting them back in. Basically I figured when I got the assembled wheels back I'd throw new bearings in and be good to go. The parts were already ordered...

In short, I didn't expect to drop off complete wheels and get some of the pieces back

Probably the biggest mistake people make in changing bearings in the wheels is not drilling out the stakes deep or big enough, or even know the stakes are there. When they are staked it compresses about 4-5 threads together, if not more. You need to drill deep enough and then the seal cover spins right out with a drift or a proper made tool.
I would say you were lucky you found a powder coater who would do the disassembly, most won't. But at this point I don't know if you were lucky or not.

Recovery phase: So the shop is attempting to make things right. They placed an order for the parts they threw away but forgot to order everything. I'm still short the front bearing retaining ring. I can get everything pretty much back together without it but just wont be able to mount the wheel up yet. They are having the part shipped to me but I'm hoping I can find one locally so I can things all buttoned up rather than waiting a week for the mailed part.

I've found some helpful guides for the front wheel and the exploded parts diagram makes it pretty clear but I'm having trouble finding any write-ups on the rear. Does anyone have an image that's a little more clear than the factory parts diagram that shows the order of assembly for the rear wheel?

The rear wheel has me a bit confused - it seems like the dampers are all that keeps the hub attached to the wheel. Maybe once the bearings, sleeves, and dust shields are in place it tightens up but as far as I can tell right now it seems like the axle will be all that holds it together from the sides.

Thanks!

Wheels are back together!
