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

Subject: [FlyRotary] bearing in mazda g/box
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.
