Hi MM,

One way I change seals when it's not worth buying one as I'd have to wait days to to get one in here is I just swap
the bottom of the Briggs motor with a bottom part from another motor with a seal that's not leaking if you have a few
spare motors ,I don't even worry about the gasket getting damaged when I swap parts as I just use high temp silastic
on the mating surfaces but if you had to buy the silastic the seal would be cheaper to buy.


The common way to remove the seal is

Drill one or two small pilot holes (1/16" bit) in the metal edge of the seal face.

Be careful not to go deep β€” you don’t want to hit the crankshaft.

Thread in a self-tapping screw a few turns β€” enough to grab

Use pliers or a claw hammer to pull the screw β€” the seal will pop right out.


I don't like to drill the seals as you get metal filings and the chuck will most likely rub on the crank
so I just sharpen a small nail on a grinder and make 2 small holes in the seal by hammering the
small nail in then use a slide hammer with a self tapper on the end and pull one side then the other.


Cheers
Max.
