remove a very old oil seal from the crankcase

[Mike-Polito]

Hello - 

I am trying to remove a very old oil seal from the crankcase on my 1979 GS425. I am attempting the install screws/lift out method.

The seal is for the shift shaft, so it is somewhat small. The case is on my work bench.

The seal is hard as a rock and I am unable to get a screw into it, even after pre-drilling for it. 

Can anyone recommend a type of screw (wood, machine, self-tapping, etc)?

Thanks - 

Mike

It is a butcher method but a sharp small blade chisel that can cut it in half ???

Ive always had good results with deck screws. Hammer the tip in a bit first

I guess you've already tried the screwdriver / blunt lever through the hole, block of wood on the case for protection and lever it out?

Maybe warming the seal with a heatgun would help make it more flexible and to expand the alloy seat a little before screwing.

that little seal will come out easily enough with a flat blade screw driver….. puncture the seal midway from shaft to case seat….. pry downwards like a man ….. and it will come out
