I've seen the Stihl puller, I've seen the various Husky pullers. I've also seen the prices for each. Then there is the gammet of modified pullers from the Lysle one all the way to notched screwdrivers. What is everyone out there using?

I forge out an old chainsaw file into a hook that fits around the crank, I heat to non-mag quench in water or oil, and draw to a spring temper.

There aren't many tools out there that I won't build for myself.

Sounds pretty cool. Do you have any pics of the set up?

I bought a Lisle and it didn't last. The blade straightened out. I now have customized screwdriver which has pulled better than 25 sets without a problem.

The easiest way to pull a seal is with a drywall screw .You pierce a little hole in the metal portion with a sharp punch,ice pick whatever .Screw in the screw and pull it out .Simple as that .Even with a seal puller you are going to ruin the seal .

A little teeny seal like a Stihl 200T you can work out with a pair of ice picks .

The Stihl puller worked real slick on the one 260 that I have used it on the flywheel side. I think anything is going to tear up the seal?

i've always hesitated to try the drywall screw thing cause i'm not certain how i'm gonna keep the metal pieces from dropping in to the case/bearings. eh?

I use my shop vac to pull filings/bits out from around the crank end and bearing after pulling a seal. Bigger concern for me is making sure I don't damage the case in the seal area. Some saws have delicate little rings of mag around the seals (and small seals that don't give much 'safety' room around the drywall screw). Also gotta be careful to not drill or screw too deep and damage the bearing's ball cage. On saws where I don't want to use drywall screws, I instead use modified screwdrivers and such under the metal ring of the seal................and pull 'em with my small slide hammer.
