Power steering pump delete

[xparatroop501]

So, I have a question. I have a 66 Bronco with a 1974 302. It has manual steering rack and manual steering box but does have the power steering pump on it. I got it running again today and at least got to drive it a bit, but it was running hot, about 220-230. The power steering pump started leaking shooting fluid all over and making a metal on metal scratching noise that varied with the RPMs of the motor. Is there a bracket to delete the power steering pump? The power steering pump inlet and outlet are connected to each other so it's just recycling hot fluid back into it Which I think caused it to overheat the fluid. If there is a bracket that will still spin the crank and take off the power steering pump that would be what I would want to do for now. Any help on if I am correct on the pump overhearing and if there is a delete for the pump would be appreciated.

Why can't you just remove the pump and get a fan belt for a non PS engine? There is no PS delete pulley for a 66 Bronco! (Or for a 74 for that matter.)

Maybe I am a complete dummy, but by looking at it I was trying to figure out the same thing. If I take the ps pump off that new belt will be only for the fan and crank. How would you get it on?

Usually, an engine with a power steering pump will have two belts. One belt, closest to the engine, will drive the alternator, passing around the water pump, crankshaft and alternator pulleys. The other belt drives the power steering pump, passing around the water pump, crankshaft and power steering pump pulleys. That does require that the water pump and crankshaft pulleys be a double groove pulley.

To remove the power steering pump, remove the pump, brackets and the belt. Leaving one belt to drive the alternator.

You should have another belt that goes around the crank, water pump and alternator. If so just remove the other one.

The existing belt on the power steering goes around the crank the power steering and the fan, it is the only belt that goes around the fan currently. The other belt goes around the alternator and crank only.

...The other belt goes around the alternator and crank only.

There should be a groove in the water pump (fan) pulley that aligns with the crank and alternator pulley. You need to replace that belt with one long enough to go around all three pulleys. This would be proper even with the power steering pump belt in place.

I'll check it again, but it looked like the water pump only has 1 groove and it is not pined up with the alternator and crank. Also, do you think my assessment of the ps pump getting too hot because it just loops right back to itself.
Thanks guys, as you can tell I am new to the EBs but trying to learn everyday.

Shouldn't be any load on the pump if the hose is looped so I would think it would run pretty cool. But if it's making noises it's already bad.

 

[xparatroop501]

It shot fluid all over and was pretty hot, makes a metal on metal noise that seems to get louder with higher rpms. Engine was running hot too though, isn't. 220 to 230 degrees too hot for a 302?

If you only have one groove in the fan pulley, take the fan and pulley off and see if someone put spacers behind it to make it line up with the outer pulley on the crank and PS pump. A single groove pulley should line up with the inner groove on the crank and the alternator.

Years ago, I had the opposite of what you have. The alternator looped with the crank and single groove water pump and the PS belt just turning the pump with the crank pulley.

Just found this diagram on-line. I have to admit, I've never seen a stock application where the alternator is driven by just the crank pulley...

 

[xparatroop501]

Yes I found that last night also, my set up is just like the middle diagram. The water pump is single groove and not in line with alternator, it is further inside.

Get yourself a double groove WP pully and your problem's solved.

x2 that's the way my 74 was factory setup, with a double groove waterpump pulley.
the diagrams above are for mustang installs not EB's, EB's with factory power steering used a double grooved waterpump pulley and the alt and steering belts both go around the water pump from the crank pulley.

Yes I found that last night also, my set up is just like the middle diagram.

So, if you were poking around on-line, you probably saw several of the aftermarket v-belt setups. Those are as the rest of us have described.

On your setup, you have a groove on the water pump and crank pulley that line up. Only the alternator does not. Seems like the easiest solution is to make the alternator pulley line up with the grooves in the water pump and crank pulley.

Usually the thing that aligns the alternator pulley is the spacer between the head and the alternator. Usually one long 7/16" bolt tightens that up. Cut the spacer, then bend the other brackets to fit.

I have length of 1/4 x 1" aluminum flat bar, about 3' long, that I use as a straight-edge. I use that to, among other things, check the alignment of the
pulleys. You need the groove aligned, and you need the pulley parallel to the other pulleys.

I'd just get a 2 groove water pump pulley. It will fix the present problem and allow installing PS later when you see how it drives without it. I found one on ebey for 35 delivered.

 

[Broncobowsher]

2-groove alt pulley might be easier to find.

I appreciate all the help, I'll see what I can find online.
