Potmetal continues to grow until it just crumbles. Reaming is a
temporary fix. As someone else pointed out the bearing has probably been
lubed with 3 in 1 in the red can which is a pure mineral oil with no
rust or oxidation inhibitors and just soaking with Kroil will usually
get it going

the bearing on my triumph nickel plated so
it looks nice, I do not like the look of the brass.

Is there any reason you would ever
If it was not crumbling or expanding by now it probably will not later
so I would leave it. The problem is that the term pot metal actually
describes nothing. What was the actual formula that was used to cast
these bearings? What was the purity of the metals used? The lack of
dimensional
I don't agree that the potmetal probably never will expand. I just took an
Edison Standard Model D out of a closet where it sat untouched for several
years. The bearing was stuck. It was fine the previous time I used it.

3M Adhesive Remover, available at most NAPA stores will definitely remove any

I would be interested in knowing if it was the oil or the pot
If I remember correctly the home and triumph pot metal bearings are thick, I
would think if the shaft could be removed the bearing could be reamed out to
the correct size and it could be used. Has anyone ever tried this? Steve
