    Hey mate.

    I was looking around at some ford stuff (strut tops) and came across this site!
    I got a little excited as it deals with not only ford escort/ cortina stuff but 4age's and toyota stuff too !
    Bonus.

    Anyhow as i got to the bottom it listed a quaife rack for the ae86 and AW 11. Its not a Cusco but hey its on the subject......... Well sort of

    Wasnt sure if you are after something to suit your corolla or just being you ...and going Hmmmmm i didnt know Cusco made racks and further investigating

    Their prices seem a little $$$ but it is NZ dollars.

    Some good stuff to be found :

    The quaife racks are good, just make sure you dont get the first revision which were escort teeth on an AE86 rod.

    is that what happened Takai? bugger

    30psi, the Quaife is the fall back ($400 is reasonable i think), but someone found some Cusco branded racks, and there was chance of cheapness....
    however since i can't find any references to them bit of a pain...

    do the quaife racks have any distinguishing marks?

    edit:, damn they are gettign even cheaper! $320 for a quickrack!!

    yup, so it's like 2.5 turns lock to lock instead of 4 or 4.5 or whatever
    i'm sure there are other names for them..

    I take it this is for drift work only. why not use the ratio multipliers that are used in speedway. double the movement going to the rack from the wheel.

    this would also be for track racing so you don't need to grab wheel twice to yank it around
    i don't know if speedway loads up the front wheels as much as a circuit car with slicks?
    not sure they would be able to be engineered for the road either???
    halving the rate might make it a bit too much perhaps?

    Those Chowini Cusco racks are in Finland now. All are RHD racks and for sale cheap. Another place is asking 200€ and one private seller is asking 100€ per rack. Not sure but these might be just the inserts. Gearing is 13:1 FYI.
    One Finnish speed shop bought all the Chowini stuff.

    Mate uses speedway quick steer converter on his off roader. running big 16x10 4wd tyres on the front, his buggy does have power steer though. perhaps these things come in a few different ratios.
    I do think you would have troubles with registration.

    Quaife QSR = 27 rack gear teeth & 10 pinion gear teeth.

    Stock Manual rack = 26 rack gear teeth & 6 pinion gear teeth.

    I installed a Quaife QSR a while ago in my ae86. I did a lil bit of a write up on it found here:

    http://www.hachiroku.net/forums/showthread.php?t=696

    NOTE: if you count the rack teeth on my personal Quaife QSR you will find it has 29 rack teeth, 2 extra teeth were cut so I could take advantage of additional angle gains by installing a BV #2 rack extension/spacer kit.

    Quaife QSR - Installation & manual steering info:

    ----------------------------------------------------------------------


    AE86 Corolla manual steering rack assembly.


    Dissassembling a manual rack.
    Note: LARGE 24" crescent wrench necessary (lock/retaining nut is 48mm/2" in)




    When dissassembling just take it apart and keep everything in order, you don't need to remove the bottom bearing for the pinion gear unless you're replacing it.

    Dissassembly:
    1. Remove 2 locking nuts (#1 & 2)
    2. Remove rack guide cap nut, tension spring, rack guide. (#2)
    3. Remove pinion cap nut, pinion gear & top bearing. (#1 & 4)
    4. Slide rack gear out of housing - ONLY take it out the drivers side, as pulling it out the passenger will 'score' the pass side end bushing/guide. (#3)

    Be sure to clean out as much of the old grease as you can (I used several 3/8" extensions and a couple paper towels to clean out the inside of the rack) Also, make sure the 4 holes just before the end of of the rack housing on the passenger side are clear otherwise you may blow the steering rack boots up or suck them into the gears as it equalizes pressure from one side to the other when moving back and forth.


    Dissassembled manual rack: top rack & pinion gear set is toyota factory, bottom rack and pinion is a Quaife Quick-Steering Rack gear kit. The one pictured is a modified Quaife QSR kit with 2 extra teeth cut for additional angle with a Battle Version #2 steering angle kit (if needed).


    Manual rack pinion bearing removal
    Note: installation is flipping gear opposite way to pull bearing down pinion gear shaft.


    NOTE: Use molybdenium lithium based grease for reassembly - it came in a black 'peanut' size can from reibes/napa - kragen/shucks/checkers didn't carry it locally.

    Apply grease before assembling to:
    Rack gear teeth and lightly coat the back side of the gear tooth area.
    Pinion bearings & gear (can be packed into pinion gear area, just dont want to fill the whole rack with grease)
    Rack guide & spring as rack gear glides along/against it.

    Reassembly.
    1. Install rack gear, slide in from drivers side.
    2. Install Pinion gear, top bearing and cap/tension nut.
    When installing spin down pinion nut cap finger tight, then take a small screwdriver and by hand give a small tug to lightly 'snug' down the pinion gear and bearings - no more pressure than that is necessary, or wanted! It is supposed to be set with a inch lb torque wrench for preload but I've found that finger tight with a tiny snug sets it just as well as it was set from the factory (ie: enough to hold steady with no wobble but light enough it spins freely).
    3. Install rack guide, spring and cap/tension nut.
    I puchased a 3/4" (?) size bolt and 2 nuts from home cheapo that fit into the cap correctly so I could tighten down the cap/tension nut with ease. Snug down by hand & wrench until the rack gear/shaft has no lateral (forward/back & up/down) play, but moves left and right with no catching and/or binding.
    4. Install locking nuts.

    ----------------------------------------------------------------------

    For reference:

    AE86 Corolla Manual steering intermediate shaft vs p/s intermediate shaft


    AE86 Corolla Manual rack intermediate steering shaft installed
    Note: due to low height of manual rack, the steering shaft was 'pulled' out farther than shown in picture.

    If you do not have the manual rack intermediate steering shaft, you can take two p/s column's, cut the end off of one column at about 3.75" (3 3/4)" and weld it to the second for the extended reach.


    AE86 Corolla Manual vs PS rack pinion shaft size
    As can be seen in the picture, the p/s and manual rack pinion shafts are different sizes. Which means you cannot use the u-joint for the p/s on the manual rack or vice versa.


    AE86 Corolla Manual (top) vs P/S (bottom) driver side brackets
    I decided to go with the P/S bracket (bottom) as it is much stronger.


    AE86 Corolla Manual Rack (center & right) vs P/S (left) pass side brackets
    Note: the markings are around the areas that needed to be ground/widened to fit correctly on my originally P/S equipped vehicle. (may vary from vehicle to vehicle - not sure if it'll be necessary on anyone elses)
