belt swap on my race truck . . . .

[mustange70]

Alrighty in my race truck when in the mud boucning off the 6500 rev limiter i have tossed the power steering belt on a couple of occaasions already with the new motor, now i'm concerned with overheating if this happens at the beginning of a run. Now my question is, does anyone see any issues with swapping the alternator belt to spin the water pump and the power steering to run off just the crank?



Now i know why i'm tossing the power steering belt (the pump is vibrating from the caviation at 6grand+ rpm's throw that in with turing 38's in at least 2' deep mud, i do have a underdrive crank pulley to slow down the alt. and powersteering, i will also be installing a high volume alum. water pump) but would like to still keep the water pump spinning if i loose the power steering belt, will this work, i don't see any issues with it but would like outside input before i do this.

get deep groove pullies and/or super skinny v belts.


i run a redundant pully on the water pump. 2 grooves, one goes from tne crank, water, alt, the other is crank, water, p/s.

if its your race truck, why not go electric water pump?, theres usually a few horses there too, and you cant throw the belt off it, just run a belt for the power steering. electric pumps are about 150 more than a high volume aluminum and usually worth at least 10 hp. just a thought, JR

I run an electric on my big block, its nice, ya get fast warm ups, then if ya get done runnin and its hot, you can leave it runnin for a couple minutes and it'll cool it right down.

x3 on the electric.

So long as you line the pullies up, there's no reason why swapping the belt order would matter; but I'd look into an electric pump as well unless you are running a mechanical fan and intend to stay that way.

As for belting, on my DD I run everything redundant on the waterpump; Alt, PS, and AC.

I'm not swapping to an electric pump right now, i don't want the electrics for the time being, that and the 350 bucks for the one i want needs to be spent elseware (need to swap to 35spl outers wo i can get back to using drive flanges).

That said no one sees any issues with swapping the belts around?

[Hoxviii]

Just make sure the belt isn't going to hit anything. When I rearranged mine I thought I had a real slick setup until i went to put the AC belt on and it hit the thermostat housing

Took another 6 hours worth of fiddling and digging through piles of belts to get it right.

I've had my power steering pump cavitate on me, it brings the suck. Swapping the belt order won't matter, have at it. You could also change out your pulleys to slow it down...

[mustange70]

i already have the underdrive pulley, but swapping belts is so i don't loose the water pump when the power steering belt gets tossed.

[wyldstallyn73]

Have you looked into a larger diameter pump pulley option??

[mustange70]

Not yet, as the firs thing i wanted was to slow everything down, but do you know of someone who sells on or something to rob? (i'm running a factory ford sag pump, looks like it came off a car but i pulled it off another truck.)

[wyldstallyn73]

I have seen three different sizes of pulleys on the used sag pumps I normally keep in my parts stash- not a huge difference between them, but maybe enough in your case??

[mustange70]

Maybe, probably won't take much, you wouldn't happen to have any measurements i could compare mine to would you?

The 302 in my MX EB racer had one belt for alternator and WP and one for PS direct from crank pulley. All the pulleys were 'stock' size...and I ran a Sag PS pump. Never had any isues pitching either belt and the solid-lifter engine I ran didn't even peak until just above 7000 and routinely went well past 8 grand. Both belts were very short and kept very tight..the alt belt is short anyway and I re-clocked the PS pump to be closer to the engine (not for belt reasons..to clear the steering box I went with).

[wyldstallyn73]

I measured all the Ford application Sag pumps I had this morning
5.25
5.75
a touch below 6

The one that measured 5.75 was in a rig and hard to get an accurate eyeball on, so it could possibly be the same as the slightly less than 6 pulley.

k thanks, i will check the next time i get a chance.

It sounds like a lathe and a dinner sized chunk of aluminum is is your future

[mustange70]

And what do ya know, i have the aluminum and a buddy with a lathe
