That would be called a Torrington bearing, widely used in automatic transmissions, very tough but loves to be lubed, & yes the races are not held they are free floating. All the Japan made trans use many T-bearings, the have an unusual design for there auto trans based on manual trans concept of many large helical gears & added clutch packs to transfer torque where wanted also reverse uses a manual trans type syncro gear. Not bad stuff but difficult to work on. David R. Cook RV6A Rotary tomorrow will test Auto tune with new eng. monitor, install complete.

Charlie and Bill, yes tracy used two needle thrust bearings as I have, but in practice there is nothing to hold the thrust washers either side of the two bearings. I just worry about that, but tracy's Box has done thousands of collective hours, so I possibly should throw my worry beads away. Thanks Neil.

Neil,
If you're looking for the Mazda transmission input shaft bearing, here's a page from the parts manual. If you need the entire manual, email me at ceengland7@gmail.com & I'll send you the pdf.

I think those are the thrust bearings, to handle the thrust of the helical gears in the planetary gearset. Is that what Neil's asking about?

I believe that Tracy's gearbox uses a stack of needle bearings to lower the rpm of each bearing to a better value

Gents, I have suddenly realised that the main bearing on the Mazda
g/box input shaft would have to take 8/9000 RPM. In my search most
bearings give out at 6,000 RPM. Does anyone know just what bearing they
use? Perhaps the number?? I realise i am the optimist. Thanks Neil.
