snowblower repair questions
im having lots of trouble with my QA42A right now. the first problem is i cant keep the stupid set screws tight on the drive shaft. i replaced both keys and all the set screws with square head set screws so i can get em tighter and they still come loose. i also cant keep the pulley set screws tight. this also has a new key and set screws. how do you guys keep them tight?
my other problem is my gear box gasket. i serviced the gearbox with new gearlube and used some old gasket paper for a gasket. im thinking it might of just been too old so thats why it leaks. so question is, what kind/type of gasket paper do you guys use to make your gaskets? would also like to use the same paper for rear end gaskets too. and do you use sylicone on the gear box gaskets? thanks for your help guys

I used to have the same problem. I put blue loc-tite on the U-joint setscrews; my aftermarket pulley has a thick enough hub that I can get 2 setscrews in (both with blue loctite) and the second setscrew is long so it protrudes and has a nut and lockwasher on it as well. Hasn't come loose since.
Your gasket might have been too thin...the original is cork and is at least 1/16" thick IIRC.

I just redid a cast iron rear end and I used neoprene gasket material with RTV - no leaks for me, I am RTV happy though.

blue loctite works great like mattg said. you can buy sheets of cork at yur auto store and cut it to fit. you can if you want also rub a thin layer of gasket maker on both sides. you should also replace the outer bearing on the pulley shaft. mine turned fine but when i pulled it all apart it was shot. the seal was rotten and the bearing was close to fallen apart.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
