Experience Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. I received a scholarship from the Air Force and am currently pursuing another degree.
Question I have a 1981 Toro Snowthrower 524, Model 38040. I'm switching the 5HP (worn out) engine with a used 8HP (not as worn out). Mounting brackets etc., switch over just fine...the only problem seems to be the size of the crankshaft. The 5hp has about a 1" shaft, the 8hp has 3/4" shaft...I need the 2 slot engine pulley from the old 5hp...but the shaft on the 8hp will not accept it. Can I find the same size pulley for the smaller shaft of the 8hp? If so where? Or should I try welding the pulley with the bigger diameter shaft hole onto the smaller diamer shaft, anticipating never using the 8HP engine for something other than the snowthrower? I am stumped...please help.
Thank, Jason
Answer I bet you can find a correct size pulley but I don't know exactly where.
I'd hold off welding it as long as possible. You my be able to find a sleeve adapter.
What do you mean by a 2 slot pulley? 2 belts?
Measure the outside diameter of the pulley and the key way size and I'll check some books.
