Water Pump Bolts vs Studs for PS Pump

[stanz]

I’m building an Explorer 5.0 and reverting to the stock v belt set up (have correct timing cover and water pump). I’m using all new hardware and unclear if I should be using studs or bolts on the water pump for the ps bracket.

Which one will provide the correct belt alignment?

The pump pivots on a stud. The others are bolts, if you want to go original EB. All the front dress of the EB 289/302 works on an Explorer 302 except the harmonic damper that has to be 50oz. imbalance.

Is the stud where the ps pump pivots stock? I know wh sells the stud kit but most the broncos I've dealt with just had a long bolt there. Also seen plenty using washers to get it lined up.

I’m good with that stud. Yes, WH, Tom’s and Mustang shops all sell that stud. My question is around the water pump/timing cover bolts that attach the PS pump bracket. Mine have been missing since the aftermarket A/C was removed.

I've always just used bolts on the water pump

The water pump uses bolts. The stud that the power steering pump rotates on, screws into the head, not the water pump. The power steering pump uses a front bracket that attaches to the water pump using two of the water pump bolts. Then attaches to the stud via a nut, and then a bolt into the power steering pump main bracket for adjusting belt tightness.

I said all this in post #2. The biggest hurtle is getting the correct pulleys and harmonic damper.

Which one will provide the correct belt alignment?

Studs or bolts: either one would provide the correct alignment. The pump adjusting bracket sits against the water pump in a stock V8 Bronco set up so it's not going to matter. Provided it's a straight threaded stud we are talking about. Three items will determine the belt alignment:
Water pump pulley
Crank pulley
Steering pump pulley
Each of these when hooked up to a correct part: water pump, harmonic balancer and power steering pump will line up properly and work.

I think it's been said but the biggest issue with using the later model Explorer 5.0 motor and switching it to old school Bronco V belts will be getting the correct balancer. One like this will work.

As long as all the other parts from timing chain cover out are early Bronco V8 you should not have a problem.

The problem with the stud is it is threaded different on both ends. once you set the stud in place everything has to go on over the end of the stud so everything in front of it has to be removed. You can put the stud in the pump pivot and try to hang the pump but we are not built with enough hands to hold everything and double nut the stud in. One of Fords rube Goldberg contraptions.
