49 cub restoration project
Happy New Year ! Does anyone use a sealant on the outer side of final drive oil seals (between seal and final drive housing)? I imagine this just makes life difficult for the next person to replace the seals.

Re: 49 cub restoration project
I don't. Most seals have a thin coating that IS a sealant. More important, I believe, is making sure the bore is clean and very smooth, with NO burrs. Sometimes a previous seal replacement has involved digging out the old seal, while scratching the wall of the bore. This can become a source for leaks.

Re: 49 cub restoration project
Hi,
I guess you are replacing the oil seal on the upper shaft in the final drive, where the brake drum is.
If you find deep scratches in the metal where the seal goes, you could use a sealer on the OD of the new oil seal, to fill in the scratches.
Permatex Avation Form A Gasket is good. It is a non hardening liquid, in a small can.
NAPA sells it, here in the west USA.
I like to stir it before using it, it can settle in the can sitting.
Remember the seal should face towards the oil in the final drive, if that is the seal you are replacing. Maybe you knew already.

Re: 49 cub restoration project
I agree with Dale and Glen. If you feel a sealer is needed, use a non-hardening type like Glen mentioned. Myself, I like Permatex High Tack.
