Im looking for a y block water pump pully that runs two belts. My stock pully runs one 3/8" v belt. I want to remove it and install a double pully that will work with the dampner (double pully).

Have a look at other engines in the Ford family, centre hole and 4 bolt holes line up.

You may have to make a spacer for behind the pulley to line up with the damper,
I have a 6cyl Falcon on mine and had to space out 1/4 inch.

Will do Slick, thanks for the heads up. Are you running dual belts? Or different single pully applications?
By slick56 - 10 Years Ago
I am running single vee, but i have a dual one here (somewhere...).
I am pretty sure the front vee is a bit smaller diameter.

Slick, do you think the one on ebay will fit and line up with the double pulley dampner?

Slick, do you think the one on ebay will fit and line up with the double pulley dampner? So far all the ones I have found in the junk yard are too big in diameter, or they have different size grooves or combination of sizes. I need double 3/8 about 6" in diameter. I found a chevy one that looked perfect, but it would not line up and the direction was wrong to shim.

You will need to measure the backspace on your original pulley that lines up.
Put a ruler across the rear of the pulley and use another ruler to measure the depth.
Once you have that measurement you can email the seller and ask if they will measure
the backspace of the one they have for sale for you.
Good luck.

Darrell, I believe I have what you need.




By Outlaw56 - 10 Years Ago
Pinto, I have one exactly like that located. I have not measured the back space on it yet. I put it on the hold list because I did not want the extra pulley on the front of it. I would never use the third groove. I considered removing it but it looks to be a little more than just taking it loose.
By pintoplumber - 10 Years Ago
Darrell, it's a cast iron pulley. The third one wouldn't be removable.

do you have a truckfront cover and damper. i have a truck waterpump that uses a cast 2shiv pulley. the shaft is 3/4 on the waterpump and the waterpump is bigger on the truck pump.i have both front covers so the diference is obveous. if you ar stuck would sell the pulley and or water pump and pulley. cliff.
