Stihl puller threads into flywheel and center bolt pushes on crank stub. Same one fits many Stihls. Don't have part # handyI agree, I have pullers but that flywheel was still pretty tight to get jaws on. I'll take a picture of the intake later, it was almost torn in half. Ordered a new intake yesterday, just waiting for it now. I'll do the seals today since they're not in the way of anything else.
Puch makes a similar one for motorcycles/bosch flywheels that has two different threads/sizes to fit/work with different flywheels. I can't recall which thread works with mid-size Stihls?
