removing oil seal

[countryguyvt]

I own a 60's vintage Mott Model F4 flail mower and need to replace the leaking oil seals on the Warner gearbox. I have tried a suggested method of drilling a hole, inserting a sheet metal screw and gently levering it out.

This was done on both sides, opposite each other, to no avail; both screws broke out! I'm hoping someone will have suggestions. I read (somewhere) to apply heat from a hair dryer or heat gun. The writer said the fluids around the seals can dry up and cement the seal into the fitting. I can't get them to budge.

Drive a thin blade screw driver or something in first on one side then the opposite side and pry it out.

+1....... once you kink the outer diameter pressure on the other side will be able to make it compress enough to release from the housing. A circle is one of, if not the strongest, 2 dimensional geometric figure. Once you kink the other side, it looses it's ability to resist.

I used the "drill the hole thing too" but rather than a screw I used a rt angle SS pointed pick. On some occasions it worked some it didn't.

Years ago when I was restoring classic tractors and replacing lots of seals, I bought a seal puller from Sears (Craftsman). Sure saved a lot of fudging around. Now, I don't use it that often, but worth it's weight in gold, when I do. A small chisel, or an old screwdriver to poke holes through on each side, then hook the puller in, and work it out tugging on each side, until out of the housing. Still have them for $8.99.

If you have a small slide hammer, you can use the hole with a screw, and it comes out pretty easy.

Any auto parts store has them or $8 at Harbor Fright. Sure saves a lot of aggravation. I use deep sockets to drive them on.
