I'm an ..... and took apart the hub of my 1947 CCM Roadster thinking it would be a wise idea. Now i can't get the bloody thing back together. Not a big deal, just look for another cheap wheelset, right? Well, I would, but a 28" coaster brake wheel is damn near impossible to find. I took the wheel to a bike shop thinking that they would be able to assemble it for sure, but the tech there gave me a flat out "no". He told me he couldn't do it. And this was a bike shop that are supposedly "wheel experts". I do not want to just call it quits on this bike as i've put a ton of work into already and my girlfriend would be sad as heck cause i'm building the bike for her. Can anybody here help me out or point me in the direction of somebody who can? Please and thank you!!
COASTER BRAKE HUB EXPERTS, PLEASE HELP!

It just takes a few tries to figure it out, maybe. Make sure you have the hub the right direction. The way to do that is to try it both ways.
What kind of hub is it? We might be able to find a diagram for it.
Better yet, post a pic or two.

In the world of 21st century bicycle shops I would not expect "wheel experts" to necessarily equate with "antique coaster brake hub experts", but that's just me....
As Wildcat suggested, post a pic or at least give us a clue as to brand- somebody here will find a link to a diagram or offer a hint. If it came outta there it'll go back in. :wink:

I've searched everywhere for a diagram but couldn't come up with anything. It is a CCM hub from Canada and it has "37" on it which is the date it was patented. I managed to find the patent in PDF form but that didn't give me any info on how it was assembled

Internals 2.5: top piece taken out
Close up of "internals 2.5" with top piece removed
Top piece of "internals 2.5"

Triangular pieces that seem to fit nowhere
Broken bearing cage (I know where this goes)
Bolts
Everything put together the way I think it should be (I have no idea where the other triangular piece is supposed to go)
Everything put together the way I think it should be in a sort of "exploded" view

It looks similar to a Musselman hub, but not exact. These two threads may help.

A good pic of the brake arm and any markings on the hub shell will help as well.

like a previous poster said, looks like a musselman. they did private label hubs for some bike companies- sheldon brown's website has diagrams. you can check those also to see if it's identical.

check memory lane classics for parts- they just sold a cutomer of ours a clutch/driver ...'y. i'll be installing that tomorrow. :?
haha! the forum changed a contraction of "assembly" to "butt'y" !! :lol:

Now here is mine, assembled:
What I don't understand is how those caged bearing come into play. Mine do not fit like what is shown in the first pic, they are too small:
They do, however, fit perfectly into the outside of the cog, like this:
I'm not sure if it is supposed to go balls facing up:
Or balls facing down:
The other problem i am having is when the wheel is fully assembled:
The brake arm is supposed to be held still and attached to the frame, correct? But when I try holding the brake arm in place, the cog will not spin. When i let go of the brake arm, the cog spins freely in one direction and stops in the other, like it should. Any ideas?
Update: I managed to find some caged ball bearings from another CCM hub i took apart (that one was made in england, though). Anyways, they seem to fit pretty well like the bearings in the first pic. I am still having problems in regards to the spinning of the cog and it's relationship to the brake arm.

I looked through the pics and didn't see the set of bearings that go on the inside of the cog. If you assembled all the parts and it still isn't working, and was before you took it apart, maybe one of the parts is reversed. The top piece on the internals (from your pic) that goes in the snap ring, is that identical on both sides?
