Interesting read, or at least I found it to be...

Explanation is good, but $450 a pulley can buy a lot of belts.




Have you tried belt dressing? How about the pitch, is it the right belt pitch?

One question have you tried turning the snowblower by hand at the PTO drive. On my Ford tractor I can grasp the PTO pulley on the motor & turn the snowblower easily. I still have the belt that was on the snowblower when I purchased the tractor & it does not show any wear. I did put a Kevlar belt on it this year so that I knew that I did get the proper size belt. The size is 1/2" X 38" Heavy Duty Kevlar/Aramid Cord Belt & this seems to work very good with no wear.

Yes Charlie, every thing turns easy. Mine uses a 1/2 x 37 belt.

Could it be that a 37 inch belt is to short as in not making enough contact with the pulleys. I do not know if this would make any difference but might be something to try.

how you checked for any nicks and/or burs on the pulleys?

nicks and/or burs on the pulley will short the life of a belt.

Also check all your bearings,  you might have a bearing going bad.

if you belt is getting hot - I would say you have a bearing going bad.

Chris, could you post a picture of yours , if you can get to it easily.

Yes I can tomorrow. You should know though that my blower is belt driven to the pto shaft and pto driven to the blower. Then belt driven to the sprockets. Sounds complicated but no right angle belt turns and runs smoothly. If your motor drives the blower via a belt then the your project is going to get more involved because of the right angle mule drive.

If you break in your belt before using it,it should last alot longer.Start tractor and engage the blower and let the belt warm up for 10-15 minutes.Belt will get pretty darn hot.Then shut the tractor off and let the belt cool down all the way. Don't use the blower just engage it at about 1/2 throttle and walk away.

 

The belt May require several heat cycles before the rubber fully vulcanizes (or cures) to the shape of your pulleys.But once it does the belt will run cool to the touch.I wouldn't use it unless the belt is running cool.

 

If you just pop the belt on and go out and start using it without breaking it in the belt will overheat and stretch out of shape a bit and the woven coating on the belt will wear through prematurely.

 

The Red Armid fiber Kevlar belts take a couple heat cycles to get them fully broken in.But afterwards they run very cool and last alot longer than a conventional kevlar corded belt.

Something is not aligned correctly! Make sure the engine mounts are not fagged out! And 1 spring should be plenty. Mine only has a tiny spring and it will stall that diesel at full song dead! My belt is at least 3 years old too.
Make sure pulleys are aligned and not tipped away or into each other, and make sure the gearbox is not loose and flopping around.
And the driveshaft is free to slide in and out so it doesnt twist the box and throw the belt.
Mine runs off the small pulley too.Not the big one, only the deck uses that pulley.

I believe my gear box pulley is tipped a small amount , at the top, away from the engine. so that makes it rub more on the engine side of the belt, which would cause wear there, so as it wears, it begins to go deeper into the pulleys and eventually the spring will loose tension and let the belt slip and just get worse as its used. So will have to take the blower off and the front piece with the gear box and fix it up. Will post a picture of it soon.

But I still believe it should have two belts to operate it properly, just my opinion.

Some pictures. And notice where the belt is made. I'll post it in MH81 Allen's post about where stuff is made.

Your pulleys being out of alignment will wear your belts pretty fast

Had thee same issue on my 1972 AMC Javelin's alternator, belt wore the same as yours

It was out of alignment and wore the belt fast, Realigned the pulleys and problem solved
