New Drive Belt Burning Hot

[LarryJohnson]

If you can make the pulleys whistle when you blow air on them, I would say the bearings are worn. A good bearing should not make noise. That and a slightly short belt will heat up quickly.

The pulleys began whisling because they were spinning about 5000rpm. bearings are good.

5000 RPMs? Ok, ain’t worth any more of my help, your know more than me. Good Luck.

The belt is spec. Guides are on the outside. Idlers spin fast enought to whistle while compressed air is blown over them.
Belt S's through the idler. Had to really squeeze the belt between idler pulleys.

That’s the correct belt. Something else is wrong.

Double check the routing at the steering wheel shaft.

Double-checked the alignment at the steering. Top of belt rubs against the bottom of L-guide. Would that cause it?

The guide should be at a 90 degree angle. Something doesn’t look right with that idler. It looks like the belt is riding too high. Are all of your pulleys bolted down tight? Something is out of whack.

What do you mean, the guide should be at a 90 degree angle? 90 degrees from what?
Seems like it is as shown in manual, no?

The idler looks like it is the wrong one.

90 degrees to the deck. In other words, the inside angle should be the same height off the deck as the other end. A perfect L is 90 degrees as well. I agree with @StarTech. That looks like the wrong idler.

Is that the one where steering post has to be remove and the steering post goes inside the belt? I believe it is.

Good call. The top of the idler is worn. I never imagined it was worn so much.
With a new idler, woudn't the belt still rub against the bottom of the L-bar.
