    OK. I'm stumped. I am trying to remove the half axle from the rear brake drum. It is not budging. I need some advice before I put it in the press. I got the brake shoes and all out. The pivot points on the shoes were actually broken off and pieces of them floating about in the hub.I got a metal seal out and a nasty felt washer/seal as well, items 32 & 33 on group 20 in the IPB. Everything is covered in thick black grease, so that is not helping. So am I correct in thinking that I just need to press on the threaded end to force out the bearings and axle? Is there a threaded retainer or circlip in there some place that will cause me grief?

    Item 47 on your IPB. The circlip that retains the bearing in the brake drum.

    OK. Duh. Somehow I missed that. Part of my issue was the flat washer on top of the bearing. It was basically pressed into place and looked like part of the hub. I tried pulling on it with scribes with no luck. I used a diamond point chisel and finally got it to move a little bit but ended up drilling holes in it on either side to get a purchase on it and finally got it out. Once I scraped all the black grease out I could see the cir-clip and it came right out. The bearing came out without issue then. Whew. I just need the axle pieces as the sprocket on the brake hub is pretty worn and I plan to get a new one. Thanks for pointing me in the right direction.

    Good time to think about a one piece axle from Don Pender Madass on this forum. www.tritonmotorcycleparts.com

    well if your sprocket is worn and the bearing is not a press fit, a better option is a proper cush drive hub, which is a direct replacement and of course has the One Piece Axle. GEDC4495.JPG
