Outer race loose

Ok, so here's a good example.
Use a pointed punch and dent the race seat area of the drum right where the race normally sits and then use red loctite liberally when reinstalling the race.
Basically it just makes the race tight in the drum and the loctite reinforces the race where it might not quite come into contact with the drum surface, as well as kinda glues it in.

You want the drum's race area and the race REALLY clean of oils when you put it in.
I have done this before and run them for years before it had a problem again so I'm sure it will get you by for awhile.
