Threw another belt

[Jeff Dodson]

Well threw another Alternator belt, this this time it shredded/ The belt was only about 1 year old, but I dont put very many miles on my truck. Ot was a Gates Belt. A friend of mine ( mechanic ) said to find a narrower with a deeper V to go farther into the pulley, and maybe find a heavier duty belt, like off of some machinery or something like that. Anybody got any ideas, what do yall use.

First things first lay some string into the pulleys to make sure they are aligned. When belts shred it is usually because misalignment caused the belt to roll over onto its back. If you hold some string tight on the pulleys you should be able to see it. If not then try carquest, they have any belt you could possibly want.

We had trouble with ambulances shreading belts to the alternator, had to change the pulley to solve the problem. I agree it could be alignment too.

Alt Belt Idler Pulley

See the link in my "Signature" for photo. Autozone part # 45954 and get a bolt 3/8"-16 x 1-1/2" hex flanged cap screw. The pulley cannot be larger than 4" OD.
Just remove the bolt from water pump and replace it with a 3/8"-16 x 1-1/2" bolt. Find a bolt with threads all the way to the head. Then get a 3/8" -16 Heli-Coil, use a Dremel tool to cut off the tang. Then thread the Heli-Coil onto the bolt all the way to the head of the bolt. Heli-Coil is to take up the slop in the pulley hole. Use flat washers to space the pulley out to line up with the belt. Belt still flops some, but at high rpm it smooths out a lot. It takes much longer to round up the parts than to install. Nothing needs to be removed or loosened except the water pump bolt. Have fun. OkieGringo

Okie, I already did that, the belt still pops up and down ( vibrates )

Ok, then get a BIG ASS crescent w(r)ench , and use the 1" knob on top of the alternator to tighten the crap outta the belt . Okiegringo

I can't seem to get the photos from www.webshots.com to go into my "signature". The original photos were on a CD but someone has overwritten them . The ones on my laptop are gone when it went 'belly-up' . Friggin' "Murphy Factor". Do I need "permission" to write up a "Tech Article" on it?

I have lost alternator belts numerous times. They were all Gates belts. I installed a Dayco belt and haven't thrown a belt yet, That was about 2 years ago and the same belt is still on it. When I kept throwing belts made by gates, I emailed them. They responded that when the engine was built there was a vibration in it. I replied to them yes it's called a diesel and all diesel engines vibrate.

Try Dayco and see how that works for you. By the way Dayco makes a diesel rated belt.

Only problem with Baja's mod is it would play havoc with anybody who goes to time that engine. It would probably have to be removed temporarily.

Thanks for the info. I have been fighting this for some time. Know where to DAYCO belts

, "I DID THAT", I just did not wanna get it so tight that it would ruin the alternator bearing

Try Advance auto parts AKA Schucks, Checker, Kregan. They have Dayco belts.
