Cheap alternative to Stihl seal puller

Do you have a pic?

don't know how to post a pic, but the description you described (Pioneer) sounds like the same puller that I use. Would have to change the ID dimensions to allow for different crank sizes.

I've never scratched a crank during a seal removal or pulling a case apart, and I've never heard of anyone scratching a crank. The metal in the crankshaft stub end is unbelievably hard.

I think he was meaning the machined seats in the (alloy) crankcase rather than the actually crankshaft. That's always my concern, trying to lever against something that won't dent easily.

Thanks.. I think I'll make some.. easier to make those than the Stihl type... Anyone have any idea what the thread pitch or thread profile is ?

don't think the thread pitch is that critical, as long as it would tighten against the seal, I think it would work. would like to know because mine doesn't work on stihl's. ( wrong shaft size. ) I don't have a lathe to experiment with, ( or the know how). if you can, you can probably sell a bunch.

That's good to hear since it's alwasy been my biggest fear when pulling a seal without the proper tools.

If you do gouge the mag..... use dirko when you put the seal back in...

The hardness of the stubs can be a bad thing though, a lot of the early 066 cranks broke on the flywheel side stub, the metal there was incredibly hard but I think the tempering process left the stubs with less shearing strength. That and running the saws with worn out sprockets causing harmonic vibration.

From my experience with Harbor Freight , if you want one, buy ten. Most of their stuff has a life span of about 2 uses then bends, breaks, or just explodes into a million pieces.
