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

But what is the recommended oil seal?

I think I'= ve traced my oil leak to that. (Tricky because found drops on
fittings n= ear oil filter base after last flight. But after wrapping
paper towels a= round the fittings and doing a ground run-up, only traces
of oil is on t= he outside of them -- likely slung up from the input shaft).

On a dif= ferent note. January last year I bought a  =E2=80=9CINA 81107TN
Cyl= indrical Roller Thrust Bearing, Polyamide Nylon Cage, Open End,
Metric, 3= 5mm ID, 52mm OD, 12mm Width, 6500rpm Maximum Rotational Speed=E2=80=9D
o= n Amazon for $18.40 to replace the input thrust bearings on my RV-3B.
(T= he stacked bearings are cutting a groove in the shaft.) Now the same
bea= ring set costs $135 and up. WTF! Did find SKF 81107TN on eBay for
$30.50= . But dang! No inflation?
