Non Hicas Power Steering Pump!

[Waldo]

is there such thing as a non hicas power steering pump for the rb20?? or is it possible to just swap in a R31 power steering pump from a rb20 or rb20det that had no power steering??

[Angry]

u'll be hard pressed to find one non hicas from a hr31 rb20 ..... possibly if u can find one off a rb20et or 20e eqviliant.. i think they were single ram .....much like the local r31s are.

Why? I use the rear stage (no HICAS) to run power steering fluid through the cooler.

Hey thats a brillant idea sk!

If you want to remove the hicas part though, you can just remove the rear housing and machine the shaft down, then bolt it back up. Easy

[PHATR32]

acutally, a easier way of doing it to remove the back cover on the pump, and remove the little vane/pump/thingy inside. it slide right out so you dont need to machine anything.

then reassemble the pump and block off the outlet.

It doesn't look as tidy thought does it?

[PHATR32]

tidy? it just a bolt in one of the outlets.

then you remove all the hicas pipiing.

well i found an old rb30 pump in the shed..and the only differance is the pulley, the hicas has 3 groove pulley where as the rb30 one has 2 groove...and the brackets are the same...so i guess its just a matter of pullling the pulleys off and swapping them

Hey SK, how have you got this all plumbed up? Have you removed the HICAS pump, and are the lines running from the Pwr str pump -> cooler -> reserviour(bypassing the hicas pump completely)?

I'm having a look at mine at the moment, and can't decide what the easiest way to connect the line from the pump to the cooler is :confused: have you used the standard line that runs past the sump to run fluid to the cooler? or put a new line in?

Any help appreciated

i think what SK was talking out was, instead of blocking the hicus outlet, you connect it to a cooler.

basicly its hicas pump-->cooler-->reserviour

therefore the ps pump does the steering, and the hicas pump does the cooling.

That's the concept, but it is actually even easier to do.

1. The pipework that comes from the rear (HICAS) power steering pump goes under the engine and up the inner guard to the HICAS solenoids under the brake master cylinder. When you remove the solenoids, leave the pipework under the engine.

2. When the hydraulic fluid comes back from the rear steering rack, it goes through the power steering cooler and back into the reservoir. So when you remove the rear steering rack and the pipe work from front to rear, leave the pipework that goes around the radiator to the power steering cooler.

3. Connect the pipe in #1 to the pipe in #2 using a peice of 1/2" rubber hose, so that the power steering fluid comes out of the rear (HICAS) pump, under the engine, through the power steering cooler and back into the reservoir.

Simple:cheers:

PS; one day I will take a picture of the R32 GTST set up and post it up, save thousands of words being written.

hey SK is it the same for 32GTR?

Yep:cheers:

[PHATR32]

ahhhh, i get it now!

SK, are you talking about using the stock hicas cooler? if thats the case, then it is very easy to do!

I though you were talking about adding a after market one.

I removed the housing on the rear of the power steering pump pulled the vanes out, reassembled it and put a blocking bolt in the rear line outlet. Looks neat and works a treat. I think phat32 already mentioned this. Takes about 5mins to do.

[46n2]

so i've spent some time with an advanced image ceation tool (mspaint ), and drawn up some pics.

Firstly, is this how the setup is before it is modified (i'm going from memory here)?...

And secondly, is this where you've joined the hose (ie - hicas pump removed completely)?

you got too much time on your hands

heh too true and even funnier, i'm at work :lol:

Hi,

I went ahead and removed the rear vane from my R32 GTSt steering pump. When you open it up at the back the van looks like a small steel wheel with a number of slots cut out of it where a number of little steel squares slot in. I removed this whole component but have later been told (by SSS at Girraween) that I should have removed the little sqaures and re-installed the wheel.

My pump is f'd at the moment. I assume because I did not re-install the wheel (maybe the tension on the belt was too high?) - don't know.

I want to take this opportunity to install a single chamber pump - has anyone installed an RB30 pump? Is it a straight fit besides swapping the pulley over? I think I heard that I need to put some washers between the bracket of the pump and the block of the engine to space it out because of the twin-cam head. Is this the case (it doesn't sound right to me).

Thanks.

Hi, I'll be removing the HICAS probably this weekend if everything goes to plan.

Just wondering, would it be possible to hook the rear outlet of the power steering pump directly to the second inlet/outlet on the power steering reservoir instead of blocking it?

I can’t use the SK’s idea of using it to run power steering fluid through the cooler as it is leaking somewhere.
