Steve--

In light of your email of yesterday telling me you felt that a paper gasket
measuring .015" was too thick to provide sufficient grip between the
abutment shoulder and hub flange to prfevent a spun bearing, this morning I
removed the left axle shaft to check the amount of protrusion of the outer
race beyond the face of the Moss gasket that I recently installed.  I was
able to pass a .004" feeler leaf--but no more--between the face of the hub
bearing's outer race and the face of the hub plus paper gasket, which is
within the specification.

Maybe this is due to the paper gasket's having already been under
compression since I installed it last week, and do you think that perhaps
this critical measurement needs to be made after one assembly/disassembly
of the axle shaft to the hub, as obviously the gasket is going to compress
a bit under torquing?

BTW I measured a new, spare paper gasket that came along with the one
installed and it is .014" thick.  In any case thanks for focusing on this
issue and I feel better knowing that apparently all is okay.

Best--Michael Oritt

I used a grocery paper sack to make a gasket with. That was 45 years ago bef=
ore I knew of sources. All BMC dealers had quit selling Healey parts by then=

 Spoke with Tom Monaco (tom's toys) and he said he'd replaced 80+ of those b=
earings which didn't sound right to me. He said the heat from the spun beari=
