Stuck pulley

blownengine · 09-18-2008, 10:52 PM

I recently picked up a Tecumseh HS50 and i started a rebuild.
But now im stuck, the old pulley is rusted onto the shaft. I have a small torch and i tried "heating and beating" but to no sucsess.
I know my uncle has a large torch i can use. Would that help? Do i just need more heat?

And second how can i remove the flywheel nut without an impact wrench?
I trid heating it like i did with the pulley but again no sucsess.

Any ideas for removing these parts?????

When I have a pulley that I just can't seem to free up I use my sawsall and cut it off. Go slow and easy when you get close to the shaft and then put a heavy chisel or a wonder bar in the cut and pry it apart. I've done this a number of times with great success.

When removing the flywheel nut, I use a deep socket and a rubber mallet. Put the socket and wrench on the nut then hit the wrench with the mallet in the direction it should turn to take it off. It's the same principle as an impact wrench, alot of force in a very short time.

Blown....go to your nearest NAPA, or something comparable to it,auto parts store and tell them that you need a pulley puller. Guaranteed to take it off unless it's been welded on. Nice part is that the next time you'll have a puller and you won't have to bust your knuckles....Ogy.

Yeah, careful with too much heat, good pullers work great.

I would say the anytime you can a justifiable reason to get a new tool is a good reason to buy one LOL
You could use a saws-all

to cut through the pulley on top of the key way and if that does not allow a chisel to spread the pulley enough to remove then cut a V in the back of the stubborn cuss so it will spread.

Judicious use of heat is fine but it is not always the answer and can create more problems. If the end of the crank is threaded,screw a bolt in it before using the puller or it may mess up the threads. A puller is probably the best bet,if not CUT.

Yea your a little late. I got that pulley off about 2 or 3 weeks ago. But i will definetly get a puller next time cause it took me about 5 sawsall blades which costs just about as much as a puller

i had the same problem before with a leaf blower and my local hardware store told me to put WD40 all over it and let it sit, it worked for me
