I drove it one time in the front yard and the water pump went out. I pulled it off pretty easily but the pulley is stuck on the pump and is not budging no matter what we try. I really need help finding means to get tje pulley off or someone who could steer me to a new/reman pump.
Any ideas ?
Thanks, Troy

Try using a puller bolted to the fan attaching holes with the jackscrew bearing against the center shaft. GMC pump rebuild kits are available on Ebay.

I can't rebuild the pump if I can't get the stupid pulley off. It's getting bent up already  TT | | | | | Joined: Feb 2004 Posts: 29,852 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,852 | How many bolts are you using? I'd suggest making a puller from steel plate that pulls on all 4 bolts at once. A piece of 1/2" plate with a fine thread nut welded to the middle for the jack bolt, and 4 bolts sharing the load should keep the pulley from bending.

You probably just need to buy a new water pump with a pulley on it. If you have bent the pulley, you will never get it straight. There are some on eBay, but they aren't cheap. It is a GMC only part. | | | | | Joined: Jun 2012 Posts: 166 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 166 | Thank you sir for the information and I will look again at eBay. I guess that's my only option now because it is been pretty good TT | | | | | Joined: Feb 2004 Posts: 29,852 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,852 | Hang onto the old one, Red. I can make a pulley, or adapt a different one to your pump shaft.
