XT2 Engine Pulley Removal

[RevB]

One more thing to try is after the penetrating oil, is to put the puller on the pulley with just enough pull to keep from bending the pulley. FIRST thread a bolt into the shaft, one long enough to hit bottom to protect the threads. The tap the bolt head with a hammer. The bolt will protect the shaft from damage. Do I have experience? I once pulled the bull sprocket from a 1942 Bucyrus-Erie drag-line. I had to borrow a heavy duty hydraulic puller from the US Army. We hid under the dragline as I pumped the puller to 5000 psi before it popped. We hid the under the dragline after reaching 1000 psi, but when it popped it was just a little dink that moved the sprocket about a quarter inch, but it was free!

In the snowmobile world, to get a clutch off a tapered shaft would have you turn the sled on its side with the clutch up and center bolt removed. Fill the cavity with oil about 7/8ths full, grease the threads of the bolt, screw it back in as tight as it will go and smack the bolt head with a small hammer. Hydraulic shock pops it off every time.

Probably wouldn't work on a:

Would a ball joint separator tool (or similar) assist?
