Thanks Bobby!

When I Google AZK35525 most pictures don't sho= w any races. Not included?

Any significant difference between= the Timken and National 350909 seals?

So there's a bunch of posts of input shaft oil = seal failures.

But what is the recommended oil seal?

I think = I've traced my oil leak to that. (Tricky because found drops on
fitting= s near oil filter base after last flight. But after wrapping
paper towe= ls around the fittings and doing a ground run-up, only traces
of oil is= on the outside of them -- likely slung up from the input shaft).

On= a different note. January last year I bought a  =E2=80=9CINA 81107TN =
Cylindrical Roller Thrust Bearing, Polyamide Nylon Cage, Open End,
= Metric, 35mm ID, 52mm OD, 12mm Width, 6500rpm Maximum Rotational Speed=E2= =80=9D
on Amazon for $18.40 to replace the input thrust bearings on my = RV-3B.
(The stacked bearings are cutting a groove in the shaft.) Now th= e same
bearing set costs $135 and up. WTF! Did find SKF 81107TN on eBay= for
$30.50. But dang! No inflation?
