Serp pulley for saginaw pwr strg pump

[bronco italiano]

Need a power steering pump pulley for serpentine /saginaw pump. Please send ID measurements of the orafice that presses into the pump. I didn't realize that there are different sizes as my '91 mustang pwr strg pump pulley was too small in diameter. Thanks, BI

If you use the 97 1 ton Ford saginaw you can use a pulley from a S15? chevy pickup.

The pump is the 1977 lincoln dual return. Thanks, BI

I have one that came off of a 87 S-10 Blazer. The pulley part number is 14100597. It has a .749" diameter shaft hole which is same as most all Saginaw except the Cardone/Napa pump which is the same as your Mustang pump. After searching high and low for a Blazer I noticed that a good number of Chevy cars have them. Probably one of the most popular pulleys in the local yard. Some have purchased new ones from Napa. The diameter of the one I have is 5 9/16". S10 pickups are bigger in diameter.
