[NSRCA-discussion] O.S. 120AX Bearing

[Bob Wilson]

Seems to me I've read some threads about the O.S.120AX rear bearing being
junk.

We'll I can verify it.  The 120AX on my Venus II practice/backup
airplane has been sounding real funky and today it was really bad.  I tore
it apart, and sure enough, the bearing is trashed.  Looks like O.S. didn't
harden it correctly.

I will try to replace with a bearing from local supplier, but did I read
somewhere that a bearing to a larger O.S. engine  will also fit?
