521 Repower

I recently repowered my 1987 521 with a Predator engine. I used the stock Toro pulley and belts. But to change the belts I actually have to remove the engine. Anyone know what size belts I need to get to make this work? I'd like to keep the stock Toro pulley if possible.

I have the part numbers for the stock belts. The problem is I can't change them unless I remove the engine. I don't know if I should go up 1 size to make them work without having to remove the engine

if the pulleys are the correct size already going up one size might be too long of a belt

I don't see why you need to remove the engine to change the belts. My Toro 3521 wasn't like that. With the engine off you can normally slip a screwdriver between the pulley and belt and pull the recoil over to roll the belt off. Just make sure the engine is off and also maybe pull the spark plug wire.

Please direct all snow blower questions to the forums and not to me with PMs.

I used a 6.5 Greyhound and used the original belts and pulley.
