My neighbor recently had the main drive pulley/shaft assembly changed out on his snow blower unit. He has it on his X324. So, $600.00 later and it will not keep a belt on it. He just called me and said it just threw it again. I am not too savvy on snow blowers, so am asking someone on here to perhaps offer some advice. He is 75 years old, and getting frustrated, as I would be, also. Thanks, guys for any help for us here.

Pulley alignment could be one cause. Another would be if a pulley doesn't spin as free as it should, primarily an idler pulley with bad bearings. Worn pulkeys could be another cause. I am ruling out bent shaft if he just had it replaced.

Now, i watched this thing run this morning. I noticed the idler pulley was kinda sloppy. Could this be an issue? I really would love to help this guy take care of this problem. He also put on a belt 1/2" shorter, and it still jumped.

He also needs to be sure he gets the belt from John Deere. I see more problems when owners try to go cheap on their belts. JD belts are made to strict specifications - and going aftermarket will cause problems.

The idler pulley being loose on the shaft could be part of the problem. Like TMO mentioned John Deere has different specs on a lot of their belts so normal off the shelf belts sometimes wont work.

The first thing is to make sure the belt is right. Then I would look in to the sloppy idler pulley.

Also make sure none of the pulley edges are bent, if the lip is bent out or in it can cause it to throw a belt.

:ditto:

Thats the same case for Bolens stuff. Normal off the shelf belts will disintegrate in a short time span.
