Snow Blower Disassembly

Recommended Posts

I'm in the process of disassembling my 36” snow blower. I've run into a couple of snags. The key on the drive pulley is sheared and the pulley has spun about a quarter turn. So far I've been unable to remove it. I've tried penetrating oil, heating with a MAPP torch and lots of pounding and prying. Any other suggestions? Also, how do you remove the auger bearings? I've got the locking collars loose but they don't seem to be attached to the bearings as the exploded views indicate. The snow blower originally came from a 1975 Allis-Chalmers. From the manuals I've downloaded it appears that the snowblower design hasn't changed since at least the late 1960's up to the present.

If the pulley has spun it will probably be cheaper to replace it rather than repair it. So, don't be afraid to destroy it when removing. But, I would try and save the shaft. Try holding the shaft with a pipe wrench and turning the pulley with another pipe wrench. That may move it into a looser position so you can beat it off. If that doesn't work, and you don't have an acetylene torch, grind the pulley hub until it is thin enough to split it with a chisel. The bearings will probably have to be beat off too. An automotive tie rod fork comes in real handy. You’re right the snowthrowers haven’t changed much.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
