Thanks Bobby!

When I Google AZK35525 most pictures don't show any r= aces. Not included?

Any significant difference between the Ti= mken and National 35090= 9 seals?

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

But what is the recommended oil seal?

I think I've tra= ced my oil leak to that. (Tricky because found drops on
fittings near o= il filter base after last flight. But after wrapping
paper towels aroun= d 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 diffe= rent note. January last year I bought a  =E2=80=9CINA 81107TN
Cyli= ndrical 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 the same bearing set costs $135 and up. WTF! Did find SKF 81107TN on eBay for
$= 30.50. But dang! No inflation?
