What I have is a 302 with a 3 groove pulley on the crank. the alt lines and can tension belt , the water pump is the problem because this mav doesent have power steering. does anyone have an idea of how to handle this? is there a tensioner thats avaliable to solve this problem? The only other thing I can see to do is change out the pump pulley and I dont know if thats the anwser?
the alt belt should drive the water pump also. how many groves does the water pump pully have? does the water pump pully groves line up with any of the crank pully grooves
The pump pulley only has one groove and it does line with the first grove on the crank but no way to tension it
Is this a possible soultion, Get a belt that fits snuggly from the crank to the pump? no tensioner needed?
Does the alt pulley line up with the water pump??? if so get a belt that will go over all three then tension it with the alternator.
There is a way to tension it. The water pump pulley should line up with the inner pulley on the crank. Crank has 3- V belt grooves. On driver side of water pump there should be 2 holes about 4in apart that are threaded. 1 hole is closer to the block than the other. This is where the stock PS pump bracket is supposed to mount. I made a alum bracket almost the same shape as the stock brk only made small adjustments to its design.Hung a idler pulley and ,walla the idler pulley lines up perfect with the grooves on the bottom pulley and with the pulley on the water pump. Even used a PS pump fan belt that fit perfect. If you need more info you can call me. Ask on a PM and I will send my number. I have no way of posting a pic of the home made brk. hope this helps. Ron
No the alt dont line with pump. What would happen if I changed to a two groove pump pulley?I just Measured and it appears the pump groove is 7/8 inch block side of the alt groove.
mavman72. The alternator lines up with the second groove on the crank pulley, the first groove(closest to the rad) is for a AC car, requiring a idler tensioner also. The inner pulley, also a bit smaller than the first 2 is smaller in diameter. I had to resolve the same issues. used some of the original brackets and made 1 for the water pump.TTFN Ron:bananaman
The other option is to get the bottom pulley and water pump pulley from a V8 car with no AC or power steering. Then the Alternator, crank and water pump all line up and you only require 1 belt.ttfn ron
Mitch, I did basically the same thing as Daydreamer. When I eliminated my power steering, I removed the pump and added an idler to the pump bracket. Works great. I am looking into a different water pump pulley that will line up with the alternator pulley and then that belt can be used to run the water pump and the alternator can be used to tension it.

Well I'm the king of fabrication. Some say the king of jury riggin! Ah what do they know! I will fab up a tensioner. what kind of idler pulley did you use and off of what?
Mitch, I got it from a buddy that works at Chrysler. You should be able to find something at an auto parts store that will work. Then turn a shaft with a shoulder on it and tap a hole in the center so that the inner race of the bearing on your pulley will just slide on the shaft. Then weld the other end of the shaft to a plate that has been drilled and tapped to pick up the mounting holes on your bracket. If you don't have the old pump bracket you can probably fab something from scratch and eliminate the plate. Hope this helps. Lee "THE MAV" Richart
Thanks, Ill put some thought into it, Maybe use some plate aluminum for the bracket. Make her look good. thanks for the help.
the tensioner pulleys are available from parts warehouses like auto Zone. Just ask and tell them its for any ford 302 from 70 thru to 85. I bought 2 for 16.00each canadian.Available fromseveral parts manufacturers. If needed ,I can supply them or give you the part numbers and who makes them. TTFN Ron
