Power steering pump pulley

[Omie01]

I need a new power steering pump pulley, I cant find one thats exactly 6 1/4", most are 5 1/8th to 5 3/4". Does diameter matter?

Diameter would affect how fast (rpm) that the pump operates. Larger the diameter the slower the pump turns at a given engine rpm. I personally would stick to the original diameter, so 6 1/4" if that's the case. It might not make any difference but Ford did this for a reason, probably heat, pressure and flow.

Hello Omie01,

Interesting Ford Specs. here

71/ F (8 cyl. 302 exc. Boss) D0AZ-3A733-A

71/ F (8 cyl. 302 Boss, 351) D0OZ-3A733-B

D0AZ-3A733-A >> (Identify #) D0AR-3D673-A (5 5/8" OD)

D0OZ-3A733-B >> (Identify #) D0OR-3D673-B (6 1/4" OD)

I have a whole pump I'd sell for 45 shipped. Original pulley attached.

I'd find the correct one if it were me. I'm sure the engineers at Ford use that size for a reason.

In addition to the other parts you bought

I have 5 or 10 + pumps I could take the pulley off of
