ST824 burned up auger drive belt

Well a few of you guys nailed my problem of two weeks ago. My impeller froze up solid after blowing sloppy wet snow. I shut the machine down and parked it in my shop. The temperature dropped way down and the frozen slop locked the impeller right up.

Not quite alert enough to realize this happened I fired the blower up a few days later and drove it out of my shop. Then I pressed the lever to engage the auger and impeller. Nothing happened in the way of throwing snow. After a few tries I smelled the burnt belt. Took the machine back inside and then blew warm air into the mouth of the bucket with a space heater. That thawed things out and got the impeller and rakes working again. So I thought. Now when I try to blow snow I find that the impeller slips like crazy when I drive forward and load the bucket with snow. It seems to me that the burnt belt is the problem.

To replace the auger belt on my ST824 do I have to separate the bucket front end from the body of the machine? Can I simply remove the belt cover and inspection plate and get the job done that way? How much or a problem have I created for myself?

Thanks in advance. You guys are super helpful.

On that machine..I think it is easiest to take the top bolts off of the blower housing to the body, and just tip the bucket forward a few inches to give you room to work....make sure you get a belt made for blowers and not an automotive belt. Not a big least after the first time LOL

There is an Adjustment on the Idler Pulley. You might be able to Move the Pulley in to tighten it up and get it to work without changing the belt if it isn't too bad. +1 to cranman about tipping the bucket.

Cranman is right on with tipping the bucket - it only takes a couple of minutes extra and makes the job much easier. Also, +1 on choosing the correct belt. Automotive belts are cheaper, but will not last very long in a snowblower. LOL, many years ago, I had to learn that the hard way.....

Got to to my local snowblower repair shop. They sold me a 39" long belt made for the job. In researching a few things I notice that the stock belt is 39 1/2" long. Jackmels mentioned that the tensioning pulley is adjustable as well it is also spring loaded. I will trial fit the new belt and see how it looks in place. Tipping the bucket is easier with two people doing it but one person can manage.
