SuzukiSavage.com - Rear belt pully squeak

pg Serious Thumper Offline Posts: 5273 In Transit	Rear belt pully squeak 12/19/13 at 15:00:59 My understanding us the squeaking noise is just part of owning an S40. It is getting really loud. I didn't notice how bad it was till I heard my buddy go down the road. I could hear it 100 yards down the road. We adjusted the belt and back tire a little bit. Does anyone have any thoughts? Thanks and happy holidays.

could be excessive tension or alignment.

tension...
grab the belt on the low side in the middle give or take a mile...
if you can twist it 90° it's fine.

Alignment...
lift the rear wheel off the ground, take the bike outta gear and spin the wheel. Watch the belt, does it track to one side? Tighten the side it tracks to. Repeat spinning the wheel the other way. Try to get it in the middle or at least not hard against either side. If you can't getRdone, check the pulley bearings, spacers on right side, and dampers.

Do I understand this correctly: I should be able to twist the belt to a 90 degree angle if it has the proper tension? I can probably twist it to a 45 degree angle as is. Best regards.

Once you have the tension set....then play around with the alignment of the rear wheel until the belt rides down the center of the pulley. If the belt is riding up against one side....then tighten the adjuster on the side it is rubbing....or loosen the opposite side a bit and get the belt so it rides in the center. You should be able to see a small gap on both sides of the belt....it should not rub against the sides of the pulley.

Also, check the pulleys - sometimes a piece of gravel can get wedged in between the teeth, and that can/will force the belt to lean onto the pulley sidewall = squeal. Been there

It had more play in it than I can remember. But it has been a long time since I had looked at it. I can get it to move maybe a quarter inch each way. My initial thoughts was a spacer needs to be replaced. Thanks and happy holidays.

Spacers in the hub provide shock resistance when accelerating or decelerating. Try some belt dressing. it usually comes in a spray can. Also do the checks listed here.

The bearing that is on the pulley hub just seems to allow too much wobble, even on a low mileage bike.
