Paul Having grief trying to locate the bearing that Tracy uses in the Reduction box.  It is 80mm OD,  60mm ID and 4mm thick. Both sides and needles are made into the one unit.  Is there a bearing number or where can I get these??

I can't find that exact size either. Look at these two. Tracy1.jpg and Tracy.jpg
Both are RPM limited to 3600 RPM. Not good.

No need for an exact replacement. A stack of at least three needle bearings
will work well. Each bearing will rotate at 1/3 shaft speed.


Perhaps you are talking about a Ford C6 part inside the planet carrier?
Sounds like it as 80 mm is over 3 inches in diameter. Too big for
the helical gear thrust bearing. In that case the RPM is much lower.
Slauson would have it.


Randy Kempf is taking over the gear box building effort and can ship
over seas. I am going to focus on the ignition systems.
