I have borrowed a hydraulic puller a few times. We often use it in combination with the two jaws from a bearing puller. It comes with the two long bolts so it's easy to get it in position. I have yet to
defeat it. Sure makes a loud crack when it lets go

Good on Briggs if I can be bothered to borrow it. Usually not worth it.

. No good on PT Victas. Just takes off the flywheel as well then it's impossible to separate them. Norms savage clout on the boss is the only way.
