and feels really heavy to turn and is all wrong. i looped both lines that went to the PS pump. i heard that is what u have to do and thats it? is there somehting i am forgettign or am i supposed to get a non powersterring rack?

When sport compact car took the PS out of their silvia conversion all they did was unhook the lines and move the wheel from side to side to get out all of the PS fluid. And then cap off the lines. two of my friends have done this and it works great for them. the steering got easier when the fluid was removed.

Looping the lines like that causes the steering to be limited to the rate you can flow fluid through the hose. Keep in mind PS pumps create a pretty decent amount of force. They're even used for powering winches on some trucks.

ok so remove all fluid by turning the wheel then cap teh lines? ill try that tommorw c what happens

do u guys knwo if there is a diffrent chamber for grease on teh power steerign rack? it doesnt use the power steerign fluid as a lubricant fo rteh rack itself does it?

Jimmy325i

yeah it does.... the real way to go is to find a manual rack.

You'll leave enough in there to not have problems with lubrication. What you're probably feeling is the higher steering rate of the PS geared rack. Fewer turns to lock but that also means less mechanical advantage at the wheel.

Hmmm the rx7 rack must be different from the p/s racks I've have apart. Usually p/s fluid isn't used to lubricate the rack and pinion gears, just a coating of grease. When on full lock in one direction the gear on the rack shaft actually pokes out one side of the rack housing (the boot covers this though), so it'd be quite hard to seal p/s fluid that's under the pressure of the p/s pump

It doesn't lubricate the gears, but the seals inside the rack will bind if there's nothing there to keep them sliding freely.

mdouble

Good point, but any residual p/s fluid should be enough to keep the seals wet.

so what do i do without gettigna power steering r still confused ack
take out all fluid and leave some?
do i need a breather on both of the lines comming out, because it seems that if i loop them its hard to turn

Uh. You took out the power steering, so you now have manual steering. It's going to be hard to turn. What did you expect?

edit:
****, just like dudeman said, it's going to be harder than even my car, since your ratio is shittier than a manual rack.

Taelem

i wouldnt call more responsive shittier, i'd call it more labor intensive.

LOL that's what I'm thinking... of course it's harder to turn. that's the point of power steering.

TurboII RudeBoy

U CAP OFF THE LINES THAT WENT TO THE PUMP AND THEN U LOOP THE LIL 2 LINES ON THE PASSENGER SIDE OF THE RACK !!!!ASK BOOSTEDROTORS ABOUT THIS

Kahren

its not just harder its odd. i am gonna do what TurboII RudeBoy did and ask BOOSTEDROTORS about this

marcus219

i removed everything...got all the fluid out i could..ofcourse theres still going to be some in there...and put a bolt into the feed, return, and cooler...ill post how it feels.

BoostedRotors

I think the problem he is experiencing isnt necessarily that its hareder to turn, but its very notchy. From what hes told me, I am going to agre with rudeboy in saying he looped the wrong lines.
