Jordan

I would run a seperate belt for your power steering pump thats a lot of load for one belt to carry.( wrenchturner )

You should be able to run one belt for the water pump/alternator and one for the p's. You might have to change out your pulleys to find a match and maybe shim them. If you run a serpintine belt it would be ok but there is too much load for one v-belt

I agree, it is too much load for one belt, plus the heat generated from the rubbing. Corect the rubbing and change your pullys up to run two belt and you will be OK.

ok... the p/s pump was a little out of alignment cause i just kinda left off this one part of the braket, but i fixed that and it lines up now.. i got a new radiator haose that clears better. adn thisd seems to have fixed the problem(although there is no way to tell until i drive it for awhiel)

i woudl set it up with one belt for alternator and water pump, but i can;t becsaue the belt woudl hit the p/s pump. the alternator is on teh drivers siode, and i had to modify the p/s poump brakcet to move it up some so it woudl clear my steering box. and it won;t allow for 2 puilleys. i guess i coudl mvoe the alternator to the other side, but i can;t find brackets to do it.

You have already told us what the problem is, the load is causing the belt to slip at higher rpms. The heat builds up and the belt breaks.

As you well know serpentine belts handle all the various accessories easily on one belt, but the difference is that they have a much larger contact area because they wrap round the pulley, nearly 50% in most cases. Unless you can get a very large contact patch, you are going to have slippage. The reason you don't see more than 3 points of contact on v belts is because more than this reduces the contact patch to a very small area. What you are trying to do will not work and any configuration of it will be equally unsucessfull unless you radically increase the size of the pulleys which is probably not practical because you would have to increase the crank pulley in an equal proportion to keep the others running at proper rpm's.

I don't know what you're working on but can you change pulleys and convert to serp belt?

When you are looking for serpintine pulleys at the junk yard keep your eyes peeled for a compressor bracket.

belt/bracket

personal message me about a bracket for your ac, i have a few.

additionally i never caught what this guy working on with this belt problem. i see a picture of a earlier model s10 blazer or something similar.

if this is the case - my friend had one doing the same thing.
it is stock with that belt, so the set up cant be that bad.

his problem was the lip on the balancer/tensioner whatever the heck it is was wore out. put a new one one and thumbs up.

If going to a serpentine belt setup, be carefull.

The later model serpentine belts (after 88) have a reverse rotation water pump.

It sounds to me that wit your alternayor on the drivers side, that yours is a short water pump setup (pre 69)' Can you get a setup from the 70s and put the alternator on the other side. This means changing the water pump also. This should solve your problem and also give more room for your A/C.



ps...Hey Henry, didn't know that you hung out here.

Harry

I have a friend with a 1884 camaro that had a similar problem, he put a smaller belt on it, and it fixed the problem, just a thought.
