I am in the process of putting my 93 22re 2wd pickup together after replacing the head. When I got the truck I had to tow it home as the previous owner took everything apart and put the pieces in the bed of the truck. Luckily, the reassembly has gone pretty smoothly thanks to these forums and tons of pictures.

As I was going to install the belts, I noticed one did not line up correctly. The belt that connects the AC, Idler Pulley, and Crank Shaft does not fit. The air condition pulley sits out further than the other two pulleys. Has anyone else ever had this problem? Thanks!

Chck the harmonic balancer. Sometimes they start to come apart and do not line up with the other pulleys

Birdland

What is the harmonic balancer?

bbrideau

its the outside pulley on the crankshaft.

if the AC pulley is further out than the others, is the AC pump installed correctly? should be something like this:

tat power steering idler looks..... interesting? looks like somethings missing haha

yes, ignore that...found pic on google

From the pictures, I see that three belts are used for the entire assembly. Would it be possible to use one belt and run from the ac compressor to the crank shaft to the power steering pump and to one of the idler pulleys? If I used that route, the idler pulley beneath the ac pulley would not be used. Has anyone seen this setup?

Pretty sure that wont work as the 3 belts are in different planes. If you moved brackets I'm sure you could figure it out to be similar to serpentine belt setup like you're describing. Easier to stick with stock though. If yours won't fit there is an issue somewhere just gotta figure out what's misaligned.

Here is a picture of my setup. If you look at my compressor, notice the pulley sticks out further. As far as I know, this is the stock compressor. Is there a way to get a different pulley for the compressor? The previous owner had to of run one belt between power steering, crank shaft, idler, and compressor. Let me know what you think

bbrideau

your compressor sits to far forward form the looks of it.

can u get a straight down shot from the top of the motor so we can see the alignment of pulleys a bit better?

Birdland

I'll take a picture as soon as I get home. The compressor pulley does sit further forward but the mounting bracket is correct. Still don't know what it could be

bbrideau

actually now that i look at the 2 pictures, it looks like your ac pulley is on backwards, i could be wrong but it looks different than the first picture, could even be the wrong compressor

Birdland

I thought it was on backwards as well but took it apart and can't flip it around. What stumps me is that the previous owner had ac in this truck

looks backwards to me as well. looked at my truck and online at pics - still looks backwards.

So after trying to turn the pulley around (failed), I bought a larger belt and ran it from the a/c compressor, crank shaft, idler pulley, and power steering. I'm going to try and get the truck running tonight and see if the belt slips at all. Hopefully this will work.

bbrideau

how is the tension on the belt, looks like your idler pulley is maxed out. I just looked through loads of images of the 22re compressor and then one came up for a 3vz and the pulley you have on the ac compressor looks similar to the 3vz one, maybe PO swapped pulleys or something at some time. but every 22re one i look at has the belt pully closer to the pump, opposite of how yours looks. But if it works this way then hats off to you!

I'm not sure if that setup is a good idea, it doesn't look like it has enough friction to rotate the pulleys consistently.

A Serpentine belt wraps around the pulleys through a series of curves to allow up to 50% of the surface area of the pulley to have direct contact with the belt. This causes more friction and keeps the belt from slipping. That's why there's 3 belts on our trucks and not just one, it doesn't have enough friction to hold the belts in place.

The other issues are tension and rubbing the edges. It may fit, but you might start to fray the belt on one side, causing it to fail. Also, too little tension and the belt will slip for sure, too much and it'll break under high heat or after water exposure in the winter.

I'd highly recommend fixing the pulley to match up correctly and run 3 belts. You run the risk of breaking the belt, leaving you dead in the water and having to tow it again. Also, not sure if they are non-interference engines, meaning you could really mess up the engine if it breaks a belt.

bbrideau

accessory belts have nothing to do with the valve train, 22re - timing chain, 3vzfe timing belt, which is completely separate form all other belts on the 3vz. and yes the 22re is an interference head. I do agree with you about getting the correct belt routing. If what he has works for him til he can do that cool. I would sooner run the 2 belts and not run a/c belt until it was fixed properly but that's just me.

x2 just skip the AC belt until you can figure out that pulley. that's what i've been doing since it's going to cost a fortune to work on an r12 AC system.
