Last summer I had to change my engine to a 92-93 engine from a 4x4.

I got rid of the bad engine before realizing the serpentine pulley is recessed almost a half inch out of alignment from the water pump and other pulleys on the accessory mount.

Half of my belt shredded and went into the cooling fan and burned it up, so I need to do something about the problem before putting on a new belt. I'm still not sure why the fuse didn't blow when it happened.

Are the crankshaft pulley shims that Summit and other places sell safe to use? I'm worried about it being out of alignment and making the pulley wobble a little.

I don't know if I could get a correct pulley from a junkyard or not. When I had an 89 350 engine in it, the pulley was the correct length, so they must have changed them on the 92-93 model.

Thanks.

 

If it was my car I would look around at the junkyards for the right pulley. I have spent a few days looking for and trying different pulleys, knowing the owner helps because you can take a few home to try and bring them back if they don't work. Keep looking and I think you will find the correct pulley, Good luck.

 

Far better than hacking your way around the problem somehow.

As common as engines using that system are, shouldn't be the slightest bit of trouble finding one. Check 87-up trucks.

They didn't change them that I'm aware of.

THINK: look at the water pump and the power steering. Where is the pulley located on those, front to rear? How are you going to move that any further inwards? Then given that reality, how can it POSSIBLY be right for a pulley to be a half inch closer to the motor?

Might be something as simple as, you have it turned around backwards.

 

Does anyone have the correct depth measurements for the original pulley? I'm beginning to think it could be a 94-95 now, but the block casting numbers are the same as the earlier TPI engines even though this one has flat lifters. It already has the holes drilled for the spider, so if (no, when) I upgrade the lifters and cam in the future, I won't need another block or need to use an expensive retro roller system.

I will try to find the correct pulley for it this spring, but right now I can't be out going through junkyards because my health is not that great.

I did what I knew would work for now until I can get another one and bought the shims from Summit Racing.

They actually look like these ones with three holes though.

Using all three, the belt lined up perfect, so I guess it was only 3/8" off, but still enough to ruin the belt.

I wish I knew why the fuse didn't simply blow when the piece of belt got tangled in the fan. Besides the fan motor and connector, it also fried the relay contacts. The old relay had to be pried out because it was a little melted and even made crackling noises when removing, but I was able to slit an emery board to clean the connectors inside the socket. I want to get another socket altogether, which is something I'll probably probably need from a junkyard since the parts stores don't seem to carry them and I don't even want to price them at the dealer.

The belt also shred into into smaller pieces around the shaft itself and had to be partially cut out.

Everything is working good again. I paid $12.99 for the fan plug at AutoZone and $11 for the relay at Advance Auto with a discount code and already had a spare belt.

When I told them what happened at Advance, the manager overheard and was nice enough to give me a new fan motor for free since I bought it new from them the first time. They said they don't do that for just anyone, but I buy a lot of stuff from them for not only myself, but for family members using discount codes. I think they probably just felt sorry for me. Being a woman helps sometimes since many men think we're helpless when it comes to working on cars. Not all of you, just many of you.

 

Why dont you take a picture of the misalignment.

 

This is correct for a late 3rd gen serpentine system.

 

I'm somewhat reluctant to take the shims back off right now, but can try for a warmer day when I have the time. I didn't want to work on it yesterday, but had no choice since It's my only car right now. I can snap a shot with the shims in place, but that wouldn't give the desired results.

Thank you! That will make things easier! These cars are getting scarce around here, especially with an engine still in place, so it will most likely come from a truck or even a Caprice if they are the same.

 

You know if you cant find one you can always buy an underdrive pulley that fits... But hopefully now that you know the correct size you should be able to find a cheap one somewhere pretty easily.

I made that picture years ago when my motor was apart for someone who needed it, glad to see it's finally useful to someone else.

Below is a pic I snapped with a tape measure in place to show the new distance from the balancer.

See the shiny shims? WOW! Say that fast ten times!!! LOL!

It looks like it's only off about an 1/8" now from the pic you took, InfernalVortex.

Thanks for the part number, tunedperformanc!

This should get me by until spring and I'll get the new pulley and belt at the same time. I'm not sure how old this belt is.

That lower radiator hose looks much worse in the pic than it does with the bare eye.
