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

Hi, I bought this snowblower from HD last year. Used it about 3 times. This year it started right up but the auger didn't turn. I took the belt cover off and saw that both attachment belts were destroyed/shredded. I bought two new belts, put them on, and I see that the attachment pulleys on the engine shaft do not line up with the attachment pulley. I see no way of fixing this and the manual is worse than useless. Can anyone help?

Thank you,

Pete

The drive pulley, the smaller on one the engine crankshaft, is held in place by one or two set screws. Undoing the set screws and line it up by eyeball with the lower pulleys.

It's possibly the pulley could have been put on backwards. Check the pictures in the online service manual.

Thank you, but it isn't the drive pulley that is out of alignment. Its the attachment pulleys (2). I will look at the documentation you mention, but I do not see where these pulleys are movable.

He means even though the drive pulley looks okay that still is the one you have to move in or out as the attachment pulleys don't move.

Unfortunately Ariens does not have a service manual for this model (921002). Only an owner's manual that says nothing regarding pulley/belt alignment. Any other ideas?

Thanks!

The drive pulley on the engine shaft aligns perfectly with the lower pulleys, but the attachment pulleys are off by a full pulley width if not more. If I were to move the whole pulley group in order to put the attachment pulleys right it would throw off the drive pulley by a considerable amount. Is this a good thing to do?

In answer to your question. No.

Sounds like either:

1. The pulleys attached to the auger shaft need to be moved into alignment; or
2. The engine shaft pulleys need to be aligned so the attachment pulleys are OK and then you realign the lower traction pulley.

I'd go with number 1, if possible.

Are the pulleys on hte engine shaft all attached to form one unit? My blower uses separate pulleys, a keyed shaft and a bolt/washer on the end of the shaft.

   There are three belts on this model with two pulleys.  A single tractor drive pulley and a double belted auger drive pulley.

 

>>The drive pulley on the engine shaft aligns perfectly with the lower pulleys,

 

    There is only one drive pulley on the crankshaft – That is the one closest to the engine.   It drives one pulley below not “lower pulleys”.  From the drawings it looks like the pulley has a bit of extra length which goes towards the engine.   From what you say this one is aligned but should be aligned with one pulley below.

   The two v-match belts are on a separate pulley.  That pulley can probably be slid a bit and not move the tractor drive pulley as it’s separate.  The “attachment” pulley with the two belts has a collar and the collar goes toward the engine.  If the collar is towards the intake  housing then it’s reversed and could be the problem.

Kinger, can you describe this a little better? I may be able to help.

You're saying the traction drive pulley is fine, but the dual belt auger belt alignment is off...

Assuming the engine pulley is correct, which direction and how much are the idler and/or lower pulley off?

   I missed it.  The pulley's are bolted on, not keyed and no set screws - have flats but there are two distinct pulleys and the outside one with the two belts could be reversed.  No harm in unscrewing the bold and see what there is for play if any.  As I mentioned there's an extended spacer sleve on the outer pulley which should be to towards the engine.
