Solved: removing engine pulley
how do you remove a engine pulley that appers to be rusted on and won't come off. Im trying to get it off the shaft of a 11HP briggs engine so I can put it on the new engine. even went as far and heating it with a blow torch and soaking it in a bucket of used moter-oil(right now) how do I get it off. I have removed the screw holding it. its a stacked pully. bottom is 4inchs top is 2 1/2 inchs

You need a gear/pulley puller. However, motor oil is NOT the stuff that will do the trick here, you need a penetrating oil like Liquid Wrench. The point is it should be very thin so it penetrates into the gap and helps loosen the parts.

Of course, plan-B is to buy a new pulley.

new pulley is $47 total with shipping for this rider. I figured I would try to save some money and pry the old one off as its for a customer. sense this is a double pully about 4-5 inchs long will that change things. when the engine is on the rider the bottom pully is 4inchs top is 2 1/2 inchs. looks like there both together and would come off as one piece.

As John said a pulley puller and liquid wrench. Soak it real good with liquid wrench. Put the puller on, tighten as much as possible if it does not move tap it with rubber mallet, tighten puller and repeat.

A split press plate should be used rather than a finger puller.
Less chance of damaging the pulley.

I think Stoner is right, it depends on the pulley, but a gear puller may bend the pulley. OTOH, I think you need to soak it with Liquid Wrench for a day or so with a couple of applications before you even attempt to get it off.

yeah I can't find a gear puller at the stores. went to kmart aco-hardware and home depot nonone had it. i will have to order it online at acehardware and have it sent to store and pick it up there. meanwhile i sprayed it with Liquid Wrench lets see if it works. I need it off. this engine is a briggs the new is a briggs. and the new pulley is for a tecumseh and that was the orignal engine. so If I order the new one I hope it fits. I don't know if this is the orignal pulley as the old engine is not the orignal

You could try spraying some Silikroil on it.

Even if it does not work it is great stuff to have. It is WAY better than liquid wrench to free up rusted bolts and parts. This company is legit. I have bought from them a few times. Get the large aerosol can. if you call sometimes they have specials.

also try the local auto parts shop. lot of times they have tools to rent. I think Murrays does but not sure.

and when do we get a piece of the profit for helping you do your job??

I ordered a gear puller and will pick it up today from acehardware. had it shipped to store. if they send it today you know i never new what a gear puller was untill now. I seen them and figured they where inside a engine or somthing to change gears

You are working on peoples lawn equipment and don't know what a pulley puller or gear puller is? You would also be better off looking at an automotive store or SEARS for these kinds of tools.

Theres a bit of an art in doing this. After applying the penetrating oil "Liquid Wrench" or whatever and giving it time to do its work, try the blow torch again. Be aware you are not trying to make the pulley red hot, just heat it enough so it expands a fraction without heating the shaft.
Apply the torch in a circular motion at the pulley around the shaft not at the shaft.

And remember that Liquid Wrench is flammable!
