Doesn't matter if it's a new belt. If it's a bit too long, that's your problem.

Here's one way to check it: With the engine off, engage your auger. With the auger idler pulley engaged, your belt should be almost as tight as the alternator belt on your car.

My hunch is that your belt is too long, and is just loose enough to have caused you all these problems.

Thanks, that's what I'm thinking. The only thing is that the sears site sells the same belt that I have and they are both 38 inches long. Do you think I should get a shorter one and go against the manual? I'm not sure what to do.

Yes. Get a 37 inch belt. You can probably pick one up at OReillys, or any other auto parts store. It'll probably cost you less than $10.

The Sears parts number may or may not be correct. Also, it's possible that the blower should have a 5/8th inch belt, and Sears calls for a 1/2 inch belt. It's also possible that there is just enough normal wear on both the drive and driven pulleys to keep your belt from tightening adequately.


One other thing... In most blowers, there is quite a bit of "play" or "adjustment" in the tightening mechanism. Are you sure you have it as tight as it can be?

Great, thanks. I'll pick one up tomorrow. I have tightened up everything that I can to take out the slack in the belt. I even clamped the auger handle down and used a screwdriver to push the mechanism that pushes the belt towards the pulley and it didn't work. There is play on the other side and the belt guides are all set to push the belt very close to the pulley. The shorter belt has to be the answer.

Sounds like it. As I said before, when that tensioner pulley is engaged, that belt should be TIGHT - as in, almost as tight as an alternator belt on your car. Sounds like it's nowhere near that tight.

You're right, there is play in the belt when the tensioner pulley is engaged. There are blue laws in Bergen County, NJ that prevent stores from being open on Sunday, or else I would run out now and get the belt. I'll pick it up tomorrow and report back. Thanks

I got the 37 inch belt and installed it, however it was too tight and kept the auger running the whole time. I put the 38 inch one back on and moved the tension bars to keep tension on the belt. The way the tension bars were set up there was slack in the belt, but the only other hole where I could put the tension bar, was too small to fit the bolt. I came to the conclusion that the last lawnmower shop that serviced it list the original bolt and replaced it with a bigger one and then forgot where it went and drilled out one of the other holes. Long story short, I had to drill out the other hole and put the bolt in that so now the tension bar is in the right spot and it keeps enough pressure on the belt for it to spin the auger when engaged. I wasn't able to test it out on snow, but there should be some on Friday. If it doesn't work, I will just put the 37 inch on and deal with it for the winter and maybe get a new blower over the summer. I'll let you know how it works out, but I would like to thank all of you for your time, I really appreciate it.

Snowblower help.


Thank you all for the information you provided. Just an hour ago, I was starting my snowblower and when I engaged the auger, an odd grinding sound occurred, the auger did not turn, and, after a few seconds, a burnt smoke appeared (from the pully drive mechanism housing). I disengaged the auger drive. Afterwards, when I engaged the auger, it still did not turn and the grinding sound did not occur. After reviewing this discussion forum, I checked the auger and drive shaft and determined that a piece of ice had jammed the drive shaft, preventing it from rotating freely. I removed the ice and made sure the drive shaft and auger were turning easily (of course, I unplugged the spark plug cable first). Then I removed the housing over the drive/pulley mechanism (thank you for posting the picture of this mechanism joeg679) and restarted the engine. It seems that the auger engagement mechanism did not engage the drive shaft firmly enough - thank goodness for this as I suspect I would have broken the belt or done more damage in the few seconds that I let the drive action smoke earlier. I tightened the auger engage pulley cable so that the pulley more firmly engaged and the auger started to turn. Things ran fine thereafter (for this snowstorm anyway). I noticed that the drive shaft pulley was quite loose and I will look at this later.

Lesson learned - check that drive shaft and auger turn easily before engaging. A little preventative checking will keep down the number of headaches later

^ It's also a good idea to - when you're done blowing snow - set the tires of the blower up on several 2x6s (or something similar) so that melted snow & ice drain out of the auger & impeller areas.
