Very difficult. I use two screwdrivers, one a narrow blade. With it I pry the bent end out of the groove & use the other to keep it from snapping back while using the two together. After removal, I grind a little off the bent end parallel to the seal cup for a little more room for the tool. Use a lot of heat on the hub to get the outer races to shift. Have fun! Cheers, Don.

You can use a propane torch to heat the side that has the outer race you intend to shift. I heat with a one-burner camping stove which spreads the heat more evenly. The lock rings can be loosened by a hook spanner but the front adjuster needs a special tool that is not available, to my knowledge. The races are usually very tight in the hub, requiring lots of heat. Be prepared for bad news after cleaning the bearings. Cheers, Don.

Don,

On second thought, I may just leave it be for now.
The lock ring piece (stud) has some thread issues... I will need to focus on that...Doing some head scratching on how to repair the threads inside the wheel ...they are stripped...
The bearings seem to be pretty good, so I'l just clean out the wheel, fix the thread.

If the threads are stripped It will be easier to replace the hub. They do turn up a swap meets & on fleabay. If only damaged some, make a saw cut or two in the steel fitting leaving sharp edges. With care, you can use it as a tool to re-cut the internal threads in aluminum. You will have to frequently remove the part to clean out the material from the slots. 1/16in side play at the rim is specified. Cheers, Don.

Thanks Don,
I'll take a close look and see if that is viable.

FWIW I hate the idea (and cost) of buying a new hub,...
I'd like to keep here as close as possible to the parts it was ...That said It is for riding not just staring at...

happy Holidays
Tim

Alternatives to a new hub are a custom bearing adjuster with larger diameter & recut hub to match or machine the hub out to take a repair sleeve with the proper threads as is done for Triumphs with stripped out exhaust port threads. Either is likely to cost more than a used hub, which is not rare & would require the hub to be stripped. That is why I suggested the latter. Cheers, Don.
