I have a Lisle seal puller and frankly I do not think it works very well for saws. The seals are to small to get it hooked in and the lip on the tool I have broken twice. I also tried to find some spare pieces to replace what I broke and have not found them yet. For me a good ole sheet metal screw and a screw driver has never let me down.
Before you put the puller ( any puller ) no matter if is oem or homemade tap the seal with a small punch around to move it a little then the pullers works better.
Theese Lislie pullers are original bull............. i have buy 2-3 of them and never can pull a seal out
