Hello everyone

Ok, I am replacing the bearing in the hubs on the rear axle of my TC. Now
as I understand it this is a simple tangential load bearing. My question is
that the new bearing is different on either side. The old bearing is the
same on both sides. Does it matter which way the new bearing goes into the
hub? I think not maybe, any opinion.

I made a quick web page that has the pictures of each bearing old and new at

http://hometown.aol.com//jtpaki/bearing.html">bearing pictures
for those of you on AOL

http://hometown.aol.com//jtpaki/bearing.html (for the rest of you)

The old bearing is: R&M of England part # LJ40
The new bearing is: KOYO of Japan part # 72088GC3

thanks

My reference books do not cover Japanese, but a 7208 is a THRUST bearing, of
the sort found either side of the Crown-wheel (which are 7207, one size
down).
They are totally unsuitable for the rear hubs, for which the correct bearing
was the
R & M LJBL40 which had 12 or 13 balls. modern equivalent is the M208,
although many people fit the cheaper 6208 which only has 9 balls.

It would help to know who recommended these brgs. to Joe - they need to
brush up on their knowledge!

[/quote]Joe, I would highly recommend you get the bearing with the most balls and get
a "sealed" bearing which is packed with grease...don't for get the
"sheims"....

Roger, you are right, 7208 is an SKF reference number BUT

- the KOYO of Japan part # 72088GC3 just might be a thrust too, but
equally
may be correct for the non thrust rear hub (I just dont know) - I've been
led
astray in the past by numbers (including bearings) from different
manufacturers
being the same/similar - but for totally different products!!!

A case of needing to check the specification carefully!
