Seized pulley sheave just about has me beat. Original Message Jan 4, 2015 12:26 am
Trying to remove the attachement belt pulley from the engine shaft on a 9hp Tecumseh. Been at it for two days with penetrating oil, propane torched, pullers, and hammers...and it won't budge. Before I cut it off is there anything I'm missing?

Got it! Took three days off and on. Hardest one I ever faced. No allen screws but the rusted steel on steel was fused together pretty good. I was getting close to cutting it off but it finally popped. I hope the modification is worth the effort. I picked up an Ariens 926 for my son-in-law and it came with the single auger belt. Ariens latter realized that a single belt wasn't strong enough and subsequently went to double belts. I bought the double belt conversion kit to put on before I give it to him. I also bought the same conversion kit for my Ariens 11.5hp but if the pulley on that machine looks like this one I'm going to live with a single belt.

Congrats on getting it off without breaking it. Tough stuff, drive pulleys, auger pulleys, frozen wheels and impellers.
Maybe you could make up a fixture to put behind the pulley so you then put big torque on the puller say with an impact gun.
One possibility is something like two lengths of metal something like the stoutness of a lawnmower blade. Those would go in back of the pulley. Then two rods to put behind those which the puller can grab. You could then put great force on the pulley and not worry about it breaking.
