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 again. Not all potmetal of that period is defective.
Oxidized 3 in 1 is a powerful adhesive though.

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
