I have never seem a power rack and pinion apart, so there may be some obvious reason this can't be done.

The majority of racks I've seen have the pipes on the top of the unit when installed



Others, like the Mercur and the original Fiero EHPS units have the pipes on the front



The rack housings are actually two parts; an aluminum valve body/pinion carrier and a steel tube extension. What would it take to clock the steel extension 90*? I see two metal "nubs" 180* apart at the junction of the two parts. Do these align the two halves?

It would sure make it easier to mount the Corvette rack in the Fiero (with a front mounted battery tray) if the lines could be rotated 90* to the front or rear.

Thanks,

Neil

No you can not reclock the rack and pinion position, they will only go together one way.

Is that because of the rack shape or other internal restraints or simply because of the mechanical connection of the two parts?

The power rack in my 86 has the tubes on the top. 2000 TA rack. I also want a front battery box so I'm planning on re-bending the 2 tubes so they are in front of the rack. Or replace that tubing with braided tubing if it can handle the pressure.

Currently the tire tub is still out.

Just my 2 cents.

I bent the tubes to the rear, so that's not an issue. The traversing part of the lines is really not the issue, tho. At least on my install, anyway. Even if the connections were moved to the front or rear, the lowest the battery could go would be sitting on the rack and pinion housing. I can't move the battery any further forward due to the sway bar.

Yes they can be clocked. Those two "pins" are the only things that hold the two halves together. The pins have some spiral splines on them that dig in when they are installed but you can pry them out without damaging them. Then just throw a pipe wrench on the steel body and clock it as desired. You'll have to drill two new holes for the pins in the aluminum body inside the steel sleeve after you have it in position, and then hammer in the pins.

I had to do this on a Corvette steering rack for my Miata so I know it can be done.

Ok, plan "B".
There's a spot under the passenger headlight that can accommdate a battery. Check the archives. A member on here made a tray to fit. I plan on doing mine that way.

Oh yeah, the lights still open and close.

THANK YOU! Next time I have the front apart I'm going to do this. A "+" for you.
