The current one does not have a smooth pulley groove; looks like it has been plagued with rust and I think it is the root cause for premature wearing of the fan belt. Looked online with NAPA, AUTOZONE, Rock Auto and Advance Auto, no luck. I would appreciate if anyone knows where one is located and the best way to change it out without removing motor from the truck. | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | I would recommend pulling the belt, start the engine and smoothing the pulley with sand paper. You can run it for a minute with out overheating it. Pitting does not seem to affect a belt, but raised rust it tough on them.
Ebay is always a good place to start if you need to replace it.

Not for sure how it turned out.

It requires the balancer hub to be shortened about 1/4" in a lathe, and a corresponding amount of material removed from the outside diameter of the hub where it meets the large diameter part. This allows the hub to be pressed back onto the crankshaft snout far enough to align one of the pulley sheaves with the water pump pulley. The other sheave can be used to drive a power steering pump and/or an air conditioner compressor. The cost of the new parts is about $125.00, plus machining.
