1987 Bronco XLT Waterpump pulley woes !!

[cottoncuz4]

1987 Ford Bronco XLT V8 Four Wheel Drive Automatic w/ overdrive.

Hi, I am new to this forum chat my name is Greg.

I am trying to locate a water pump pulley, the vehicle is a full size bronco XLT and the engine is a fuel injected 5.0 cid. according to specs under hood and firing order. However when purchasing pulley from same vehicle at wrecking yards" more than one" the pulley I keep receiving has a larger bolt pattern, than my existing water pump and fan clutch, but both have correct outer size and depth. The existing water pump bolt pattern has 1 & 3/4" across bolt holes center to center. The pulley I keep receiving is 2 & 1/16" center to center on bolt holes. it is a serpentine belt system, The parts store has a water pump w/ this size bolt pattern for same year & app. only for a 351 cid. but it shows to use V groove type belts and pulleys.Does anyone have any Ideas on what to do, Please help !!!!!!!

can you take a picture with the measurements and post them on here. I have a bunch of parts laying around that I can compare for you. the 351 water pump should be the same as the 302. The only thing that comes to mind is non serp engines and serp engines use different water pumps. The impellers turn in opposite directions. Maybe someone replaced the waterpump with an older, Vbelt water pump. I have a Brand new water pump here and I should have the pulley too. I will look tomorrow and compare them with your photos
