cooler sizing...

The only real concern is that you mount the P/S cooler so that it is not above the P/S resevoir otherwise you'll have troubles with leaking fluid out the cap vent.
 
yeah, i knew that one from the PSC site.. my ressy will be ram-f*cked as high as it'll go on the support on that side..
 
Interesting.

But I think the trans cooler could still go down. It doesn't rely on no air bubbles for the system to work. In addition its pushing more fluid over all than power steering is.

That certainly makes sense for the power steering.
 
I just read that link and I call BS on it as far as how to mount the cooler is concerned. Fluid that is moving WILL NOT go around air it would push any "air pocket" out of the cooler and make it go back to the resevoir.
 
i tend to agree Scott... and i certainly wouldn't see how it could apply to a trans or engine oil cooler....

it is a little misleading with the drain back comment... it's probably them covering their butts...

but it is something i'll consider when plumbing this to keep warranty joy with PSC considering I'm gonna run one of their pumps, and maybe a cylinder to go with the ressy i have from them...

before you guys had replied earlier i had worked out a layout where all the coolers had the fittings on the side, so that may just be the way i go... tranny on the pass side, fittings out the side.. then oil and ps on the ds with fittings out the side...

only issue with that is, those coolers will cost me a bit more, if i had the fittings out the bottom, it's a little more of a standard sizing, thus a bit cheaper..

really this was all just so i could figure out exactly what temp a cure's to order, being there's eleventy trillion options... :doah: :haha:
 
Not completely serious here, but it is something to think about.
We are talking hydraulics.
If you look at it from a hydraulics standpoint, it seems you could mount a large tank, inline filter, plus a cooler if needed after the tank cooled it down, and run both the transmission and power steering fluid through the same system.

Most ps pumps work just fine on transmission fluid, and as long as you kept the tank low enough to keep from overfilling the tranny, it should work fine.

Vent the tank through a filter, and put a sealed cap on the power-steering pump.

I know that there has to be a reason that would not work, but at 3:30 in the morning, I can't think of it.
 
yeah, 5 gallon pale in the engine compartment!!! :haha:


interesting, but I'm sure there is a reason it wouldn't work, more than likely some sort of flow issue, tranny sucking it dry or something... i've got enough on my plate to contemplate, don't need to digest that one! :popcorn:

gonna try to actually confirm the cooler numbers today.. do a little mockup... I'll have every bit of a grand in all this when said and done.. 3 coolers, 4 remote filters, fittings and hose to do all 3 systems...
 
I personally wouldn't want the friction and bushing material that is consumed in the tranny floating through my ps pump. Tranny pumps have big iron vanes that will probably handle that "crud" better than the little bitty PS pump unit. I guess a guy could filter it really well out of the tranny and it would probably be OK.

I don't think it would be a good idea with conventional stuff, but if a guy were to design a system that refined the fluid really well, that could be pretty bitchin. I think I would also want to use aluminum or iron rings inside the PS box too. Teflon is soft enough that the crud gets pushed in to it's surface and it turns it in to a polishing ring that wears down bores.
 
Yep, thats why I would put a spin on hydraulic filter in the system. A power steering pump is nothing more than a hydraulic pump, and they handle all kinds of wear stuff in regular hydraulic systems with just an intake screen on the intake,and a fine return line spin on filter.

True, but PS systems don't have clutch material and babbit bearings floating around in the fluid, and being that the pump is so small, I would imagine the gunk would cause more problems than it does in an auto. I'd personally want to run metal piston rings in the PS box too. Like I was saying, the Teflon would absorb particles and wallow out the bore of the box.

Like you said, I think a good 10 micron filter would probably take care of all that pretty well to where you probably wouldn't notice a whole lot of difference. PS boxes are plentiful and it wouldn't matter if you needed a new casting in 10 years...pumps are even cheaper and more readily available too.
 
Sorta what made me think about it, was some instances where similar things are going on.
For instance, my 8N Ford tractor uses the same oil in the transmission, rear end and hydraulic lift.
Its just one big tank from the tranny to the rear end with the pump sitting under the gears in the rear housing.

And I think my 4 wheeler shares the engine oil with the transmission if i remember right.

Hang on, lets take this to its logical conclusion.

Plumb some flexible lines to the front and rear end, a lot of the transfer cases are already using transmission fluid, with a little work, we could wind up with only two oils for the whole truck.

Engine oil, and a combination transmission, transfer case, power steering, front and rear end oil.

Two drain plugs and you have serviced the whole truck.......
