Nothing wrong with standing by a product you believe in. I have many that I do the same with, where I feel it performs at a level higher than others and I stand by it. Same for them, and it just comes down to what you like to use and that you're happy with it.

 

What kind of modifications are needed to mount the aluminum pump in place of the stock pump?

Does the supplied pulley work with the stock belt size?

- Alan

 

You need the flow not pressure.

I have a KRC aluminium pump, it's the same as the cast iron one, the only real benefit is weght

 

The KRC pumps are very compact, light weight and easy to make a mount. They have a flat back and I used an aluminum plate drilled and tapped and just spaced it out from the block.
I too burned up a pump a year from heat. This KRC pump is good for 9000 rpm and with a remote resovior doesn't get too hot.

 

KRC's website shows a low volume, standard volume and high volume aluminum pump.

The high volume is the one you guys are running?

Any particular pulley?

Just want to make sure I get the right thing.

 

Mailalan,
Please post where you ordered from, part #'s and price once you receive your pump along with pics.
I will be getting one of those pumps once I get a few other aspects of my car taken care of and am very interested in how you make out with the order and install.
Good luck.

Thanks Norval for your pic. Not much room b/w that pump pully and your spreader bar huh? suprised I don't see a gusset supporting that spreader bar offsetting bracket to clear the pully. Will that bracket support the weight?

Hopfully someone will chime in with which volume pump & pully to order.
What engine is this going on? Is this strictly for your stock slave cylinder power steering? Norval may be running a high flow pump b/c he has the jeep box power steering unit and hydroboost so it requires extra flow. Post your application and you may only need a low to mid level flow pump. But then again high-flow can't hurt, it would keep your power steering fluid cooler.

 

I'm planning on using both the hydroboost and Jeep steering box. So I'm guessing I'll need the high volume pump.

It will be on a rebuilt 350, about 340HP.

I'm also interested in what inline cooler works good for the PS fluid. It looks like the Jeep box is very close to the headers and I expect that it gets very hot.

I thought of that too and it would be easy to install an inline cooler with the remote reservoir but I'm hoping that depending where I mount the remote reservoir that I won't need a cooler.
I'll take some readings once I get the car on the road and determine if an inline cooler is needed, I'm thinking not. My car is a street car, if your auto-x then you would need one.
Where is a good place to mount the remote reservoir?

 

How easy is it to install a frame rail fin cooler for a stock power steering unit? Does it install on the low pressure return line?

 

Yes its mounted on the lower pressure return.
Here's the fluid cooler install on a 4x4, same concept.

"This mod produced a noticeable improvement in steering feel during continuous high RPM track and street usage. It will also help to extend the power steering fluid life as well as related components merely by doing this simple 30 minute installation!"
I'm not running the car on the track so I'll hold off on this mod for right now, my remote reservoir should provide enough heat disipation.

 

That's really cool. I was debating but I think I will add one when I run the lines for the Hydro. Where's the best place to buy?

 

No idea, but from what i read it appears most people use small transmission coolers for the power steering.
I would check out summit or jegs as they should be the cheapest.
Some Cadilacs came stock with power steering coolers, junk yard anyone?
I don't know if they are decent though.

 

What years and models? I like that idea.

 

Unfortunately its more of the high perf Caddy with the coolers. Check this article out...
http://www.cadillacfaq.com/faq/answe...ler/index.html
An exerp from a Caddy forum.."Budget mod:Go to Pick a Part, check any EA/B/D falcon automatic for the auto tranny cooler. Its usually mounted on the support panel in front of the radiator.
Should cost about $20, plus you will need to buy some hose and some cleaner to rinse it out.
When you take it off, get the mounting brackets etc.
Its about the same size as the Davies Craig one. Quite easy to fit once you have the front bar off."
"I have forklift fluid in mine as it has a higher boiling point and the steering feel has improved also."
"you can get an old vt v6 cooler from a wreckers "
http://www.daviescraig.com.au/docume...ng%20cooler%22
http://www.jegs.com/webapp/wcs/store...d=40001&CT=999
Go to www.google.com and type in power steering cooler, you'll find tons of info, articles and units. Personally I would get a new cooler from Jegs for $40 then worry about a used cooler with debris jammed inside.

 

That's a neat idea. Is that a specific type of forklift fluid you use or is it hydraulic fluid?


Call me dumb, but what's a VT?

 

I have no idea what type of forklift fluid or what a VT is as I pulled those quotes from a Caddy forum in the hopes someone here could complete the mystery. But I like the idea of the forklift fluid.

 

Is there a Caddy VT out there that I haven't heard of? Is that maybe another kind of car? WHO KNOWS THIS?

 

Don't see any VT models but do see Cadillac CTS-V, STS-V and XLR-V.
As cool as it would be I would pass on the caddy power steering cooler.
You'll find them cheaper and new elsewhere.

I would like to know about the forklift fluid though....anyone?

 

I noticed on the KRC pumps website (http://www.krcpower.com/trouble.ivnu) they stated the following: "OVERHEATING PUMP AND FLUID
Power steering pumps require a hose with a vacuum rating of 28 INCHES/HG on the inlet side and .50" inside diameter. This is to keep the hose from collapsing at higher RPMs. As seen in the photo 1 to the left common hydraulic hoses may have -10 fittings on them but the inside diameter is smaller than -6, and this one is only .265". This will damage the pump because there is not enough fluid to meet its requirements.
Push-lock hose may be the proper inside diameter but the vacuum rating is only 18 INCHES/HG and as the fluid warms up this rating actually goes down. Push-lock hose will suck shut anywhere there is a bend in it, starving the pump for fluid and is likely to severely damage the pump. See photo 2.
The -6 pressure hose leaving the pump must have an operating pressure of 2,250 psi and an inside diameter of .31". Common hydraulic hoses may have the proper operating pressure range but their inside diameter is slightly smaller. See photo 3. The smaller diameter can restrict the flow to the pump. This can cause problems in your steering such as tight spots in the turns and increased driver effort. Therefore we only recommend Aeroquip AQP high-pressure power steering hose and fittings."

Now the Aeroquip PS hose they recommend is the blue hose. For those of us that want to use braided stainless hose I think that Russell power steering hose will work. The inside diameter is big enough and the pressure rating exceeds KRC's recommendations.

Plus you can use the silver Endura hose ends to keep everything the same color.

My factory pump of 30 years old or so died within 3 years on the hyraboost/jeep box setup. So i bought a pump for a hydraboost equiped station wagon, swaped the pumps in the housings and returned the old one for the core. So far so good.

Earls, Russel, and Aeroquip all sell an adapters for the pump, steering box and hydraboost....excpet for the return from the hydraboost which I made my own fitting (I think norval did as well). The internals of the gm pump are all pretty similar. I thin the biggest change is the pressure regulator valve that screws into the outlet on the pump.

I think the biggest reason peoples pumps are wearing out quickly from the chaneover to hydra/jeep setups is the fact that the pumps are old and have a lot of miles on them.

And for the record mine didn't die completely, it was suppling plenty of power while moving but at idle there was nothing.
