Any ideas how this happened and where I can get a new pulley? Anyone have this happen to them?


Driving down the road and notice power steering stopped working, experience says belt has slipped off or broken so I pull over quickly before overheating and find the water pump pulley has disintegrated, lucky it did not get tossed into the radiator.


Looking online I can not find this pulley, the ones I do find appear to be more off set, any ideas or suggestions where to find this part?

How tight was your belt? My first guess would be way too tight!

If the belt were too tight, I would expect other components' bearings to die an obnoxious screeching death before the pulley came apart like that.

I'm guessing the bolts were loose, allowing things to work back & forth. Over time, breakage happens.

Wow! Lucky it didn't cause more damage like to the radiator.
I'd think that pulley made on heck of a racket before finally letting go.

Yeah, it could be loose bolts or belt tension.
It could of also trashed the water pump in the process.
For added insurance and PM if nothing else, i myself would also replace the water pump once a new pulley is found. Boneyard.

Get a used one.

I have had a similar issue with belt squeaking and then finally jumping off of the power steering pump. After looking for a while I found the water pump pulley was wobbling and is missing a bolt. I am wondering if I will need to replace the bolt, bolt and pulley, or the whole pump. Any insight would help. Thanks

Pretty sure the part number is 53002907. Looking around they are not cheap. Thinking cruiser has the right idea. Looks like you can go back as far as an '88 XJ 4.0 for one.

If a new bolt will torque down and the pump and pulley turn smoothly, just the bolt.
If the pulley is damaged then I'd get a new pulley and if it goes on and the pump turns smoothly, the pulley and bolt.
If the pump doesn't turn smoothly, leaks out the weep hole, or the threads are messed up on the impeller, then you need a new pump. If all the holes are ok on the old pulley and it's not damaged as far as you can tell, you can probably reuse it.

I know I've seen the pulley on ebay or you can go to a pick and pull and get one .
