Drive belt tensioner - is this normal?

Just replaced the drive and auger belts on my 2006 troybilt 24" Tecumseh. I started it up without the covering and the drive belt tensioner seems to be moving a lot. Is this normal or do I need a new tensioner spring perhaps? I tightened the one bolt on the tensioner slightly (wouldn't really go further without a crazy amount of effort) but I don't think it should be bouncing that much. I also need to loosen the idler pulley for the auger belt. The new belt is quite tight and I can see the impeller moving slightly after releasing the handle. I also saw the auger belt vibrating a bit crazy after releasing the handle. I had tightened it previously.

Here's a video of the drive tensioner bouncing.

Many old machines had ' belt fingers ' to help hold slack belt into place . Yours doesn't look too bad considering the Auger Pulley is sheet metal, and could be bent .

More importantly what about the drive belt tensioner? I think I need a new spring. I will definitely loosen up the cable on the auger side.

Is the the nut loose on the arm of the drive belt tensioner.....not the tensioner pulley it self but above it where the arm is mounted to engine???

Just by looking at video....Maybe??? If not Spring is your next bet.

Yes, I bought the correct belt. It barely fit on there with me pushing the tensioner pulley out of the way.......Which makes we wonder if that spring really is bad or not because man it was tough to put it on. The size was perfect - not too long, not too short.

The bolt was tight holding the pulley to the engine. I released the tension on the spring arm and it felt really weak. I'm pretty sure it's the spring and it doesn't look too hot either. Here's a pic.

Compare my video to this video I found of Donyboy73 working on an almost identical machine to mine. The part numbers he listed in the video are the part numbers that apply to my machine as well.

His drive belt tensioner is not moving *at all*.

I'd definitely take off the tensioner, clean & lubricate the pivot area and check whether the spring needs replacing...

I am with you.....Spring!!!


Have you tried tightening the existing spring!!!


I know when some have had theirs break(curl on end of spring) breaks off so it is just like a straight rod before curled spring they take a propane torch to that now straight rod part of spring at end where the curl broke off and curl it around a pair of needle nose or pliers to a similar hook shape of spring before it broke. So then the tension of spring is a bit tighter due to smaller size. I hope that makes sense. Just a thought. Anyone??? You would have to clip off the curl one end of spring and try it or just order a new one.
