A bit of a rookie question .... I'm building up a bike from parts and am reassembling the brake hub from a QD wheel. I have all the correct parts, its just how to assemble them!

The parts book is a little hard to read, can anyone whelp me with the positioning of the the following parts ....

In the brake drum there is a sealed bearing held in place by a retaining circlip.

~ Where does the shim 67-6033 fit in the puzzle - Brake Drum or Wheel Hub?

~ Where does the Thrust Washer 65-5884 fit in the puzzle, again in the Brake Drum or the Wheel Hub?

Any assistance is gratefully received. As the bike is a build up and the wheel was incomplete, I don't have the original set up to work with.

I'll try and add a picture here:

Shim 67-6033 goes against the drum bearing before clip goes in. I think the original bearings were not sealed so the shim kept the dirt out.

Thrust washer 65-5884 goes into the hub before the bearing is pressed in. Inside the hub there is ridge for the ring to go against.

This should make the diagram more clear.

Thanks Gordo

Assume if I use a modern fully sealed bearing the shim is redundant. Most helpful.

Best to fit, grease to help it last, it could effect the hub positioning so when fitting sealed bearings rather than work out if it does I just refit them all.

I am a big fan of sealed bearings. But, I remove the outside seal and lube the bearings as normal.
