Re: pinion gear double cup bearing issue
A good modern flange sealant is either Loctite 515 or high temp 518 anaerobic flange sealant. I use the stuff on any metal to metal joint flange set up that has any tendency to leak with no sealant. A person needs no gasket with this stuff and there are no clearance change issues. I used to use Hylomar but this stuff is better.
