66-96 Ford Broncos - Early & Full Size

Recommended Posts

The water pump pulley on my 71 Bronco is out of alignment with the crank pulley and alternator pulley causing a lot of belt squeal.. My late brother-in-law told me he had replaced the original 302 motor with another out of a 74 Bronco. New radiator and looks like a new water pump possibly. No power steering. The pulley is 6" diameter and 2 1/2" deep. It looks like I need one 2 3/4"deep to get them to align. Does anyone know where to find a pulley with these dimensions? Or is there another way to remedy this?

Hi Project...,

Hmmmm..,   A bit more info please......,  Assuming you're measuring on the vehicle.

1) You might try removing the pulley to be sure there's no "shim" or "Spacer" stuck in there on the nose of the pump.

2) Ford had (as I recall) a couple diff. pumps available for a 302..., some had a longer nose. (could be the longer one in this case)

3) Is it poss. he pulled a (transplanted) 351 from that '74 ...?

4) Is it a 3-hole mount or a 4-hole...?  Some center holes are diff. as well.

5) Wrecking yards have many Ford pulleys.., as do Tomsbroncoparts.com   &  wildhorses4x4.com

I have pulled pulley. No shim. its definitely a 302. 4 hole with 1/2" center hole. Is the longer nose pump only a 1/4" difference? I have looked in TBP catalogs along with several other catalogs with no success. May have to go to a auto parts store or a junkyard as you suggested.

 "Is the longer nose pump only a 1/4" difference?"

This I don't know.   

This pulley would be "used" parts-----not shown in catalogs.  Call Toms OR Wildhorses tomorrow. I'm sure they can help.., or send you in the right direction.

Also., do we have the original harmonic balancer/crank pulley on there..? They would know this also.

(I think some had two sheaves, if memory serves)
