[TR] TR transmission bearings

[Michael Marr]

According to my shop manual, the pinion shaft bearing and the mainshaft 
center bearing, which are the same, appear to be a standard deep groove ball 
bearing, with external circlip (important!) manufactured (back then) by 
either Fischer (part no MS12 S.G.) or Hoffman (part no MS 12 K).  The 
mainshaft rear bearing is a Fischer 6206 or a Hoffman 130.

Moss lists the two larger bearings as part #525-030 and the smaller bearing 
as 525-150 at what I think are quite reasonable prices.  Maybe Peter 
Arakelian can tell you who the current manufacturer is.  It may well be 
Hoffman because Hoffman is part of RHP (which stands for Ransomes Hoffman 
Pollard, I believe), which is now owned by NSK.  I have no idea if Fischer 
still exists as a separate entity.
