The Bolens drive sheave is very long. What kind of pulley puller would do the job?

It's quiet out there. Came across this method - does it seem reasonable? Has anyone used an air chisel to remove a pulley?

The person uses an air chisel against the crankshaft and slowly raps it free.

You maybe able to use a 3 jaw puller but it's hard to say without knowing what model tractor and engine you are working on.

Farmerall, The tractor is an H14 tube frame.
The engine is a Tecumseh OH-150 (or HH-150)
The engine with drive pulley is out of the tractor on the bench. This is what the pulley looks like. Not my picture, mine is still on the engine.

OMG THAT WORKS AWESOME. YES IT WORKS! YES IT WORKS! I tried it on my 1050 with all the pto and drive pulleys. I almost cried it was so easy. Then I tried on my 1256. I ran out of air but it was working. Oh compressor just shut off I am going back out to finish the job:thThumbsU

Looks pretty easy in the video. I had to heat and cut mine off of the shaft on my HT23. I never thought of at least trying an air chisel.

It took a little more work on my 1256 but it worked. PB Blaster and some slight pressure from a pry bar, and I mean slight. Off it came. The air chisel I used was a real small crappy one and the compressor was about 120 psi. I stuck a darn bolt in the chisel and used that. Position the gun just right to make the bolt hit the crank shaft. It is a vibrating action more then a hitting or hammering that makes this work.
