O&R: Replacement for Gear Case Sealing Washer

Recommended Posts

This is probably already known here but in case anyone is looking for a replacement seal/gasket for the intake flange where it connects to a gearbox, here is a square profile O-ring that I found from McMaster-Carr that looks like a good option.  It’s Part# 4061T231 and is 11/16 ID so it make a nice snug seal on the flange.

Looks like a good replacement.

Also I've changed the title to the correct name for this part (#7-46 gear case sealing washer).

No problem Clint, I thought it was a good idea as these seals only seem to be used on engines with the reduction gearboxes.

 

Also it seems we don't have McMaster-Carr over here in the UK, I guess I should be able find something similar.
