Default Water pump pulley removal??

I have a 1978 345 . Not the big nut version. I need to remove the pulley from water pump. Do I just remove the four large phillips head screws? Or do I need a pulley puller? How do I keep the pulley from turning when I try to remove the screws ? Thx

Just use a air impact gun or purchase a strap wrench.

Clamp the water pump impeller in a vice and use a cordless drill with a #3 or 4 bit in it.

Just be careful not to bend the blades or stress the cast housing. You May find those phillips head screws are rust seized in place. Why they chose to use phillips head and not some low profile hex head is beyond me. At any rate, I've had success breaking them free by cinching around the head with vice grips. You only get about a 1/16th of a turn that way, but that's enough to free them up so that they will come out easier with a phillips driver. You just don't want to strip out those phillips slots.

Good point sb, only do the vice thing if your getting a new pump.

Question Re: Water pump pulley removal??

Does the fan simply pull off of the center shaft after removing the four bolts?
