Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I've got a 3 year old Ariens 8524 that's been used a whopping 4 or 5 times, maybe 2 hours total machine time.  Needless to say, we haven't had much snow in the past couple years!

It starts and runs great.  Auger works great.  But it wouldn't go forward.  I removed the plastic belt cover, and sure enough the belt had slipped off.  I managed to get it back on, and it will run in reverse but not in forward.  After tipping the machine forward and removing the bottom cover, I found the problem.  The pulley that the drive belt attaches to is loose and wobbles.  Looks like it's going to be a big pain in the arse to remove everything to get it out of there. 

I'm guessing a bad bushing.  Anyone have any advice or ideas?  Anyone had similar problems with their Ariens snowblower?

I am having the exact same problem my 8524 Ariens.  I replaced the drive belt.  Now only have reverse.  The friction place in loose (can be wobbled). 

What was the fix?  Can the drive pulley be tightened?

Thanks

Guys, there are different platforms of Ariens machines that have been designated 8524. The drive systems would be different depending on which you're referring to . 8524 just refers to horsepower and width. You won't get any god responses unless you give model numbers. Serial numbers would be good too.

I have a 924108. My drive pulley wobbles too . My belts never come off though. I do not have a shifting problem eather. What puzzeles me you say it will not go forward. If it is your belt coming off you will not be able to back up eather under power. Your drive pulley only turns in one direction. Your drive pulley moves in tward your engine to enguage. This is normal. Check your disk for ware and try to adjust it. Check your manual or u-tube on how to adjust it.  I'm not sure but i think It should be 1/8" play with your lever in 1st gear forward. I know some people just flip there unit on the bucket remove the access cover . Clean off all the loose rubber. Then put the unit in FIRST gear. Then spin your wheels by hand  with your lever relseased , Keep adjusting until it locks up. Then back off a half turn. Your wheel should spin free Squeese your handle a few times to check  its operation in ALL THE GEARS. If you feel drag with your handle released in ANY GEAR back it off just enough to remove the drag.
 Make sure your friction dick is clean and DRY NO GREASE ON IT. Then put your cover back on and try it. If you can't adjust it you need a new disk

Regarding the model #, it is 932104.  I had forward and reverse prior to the belt replacement, that is why this seems weird.  I ran the machine with the belt cover off and it seems fine, even when engaging the clutch.  There was a little grease on the disc and I wiped it off.  

When it is in reverse gears, the friction wheel is near the center of the disc all seems aligned.  However, the forward gears move the friction wheel out toward the edge of the disc. Now when engaged, the pressure from the wheel pushes the disc at least 1/8 th inch due to the play in the shaft.  Perhaps enough not to provide enough traction? 

Again, I don't know if this is the issue, but it is the only thing I see that looks out of place.  There is no screw on the drive pulley shaft that allows you to tighten it.  I tried loosening and tighening the clutch cable but that didn't work either. 

My other thought is perhaps I need a new friction wheel with more rubber on it.  But my reverse works fine and so did the forward gears prior to the belt change.  Any other ideas are appreciated.  Big storm coming to CT again this week and I'm sure the dealer wouldn't get it back to me for a while.

Three possible causes: 1) wrong belt installation (take some pictures of the belt loop and show us how it is installed); 2) belt tensioner is not engaged or not working properly due to incorrect installation; 3) wrong belt length - trust you got the exact same length.

I'm thinking maybe when you put the belt on you didn't get the idler on the right side of the belt thereby limiting the movement of your friction disc. Just a thought.

You could be right.  I don't have  a shop manual and put the belt on without knowing for sure what side.  

Guess it's time to find one on line and buy it.  Thanks.
