Installation

Installation is the reverse of remove ... <not>

  1. Replace Radiator with Manual one
    • Process is as described in Bentley
      • Remove Aux Fan Rail
      • Unbolt A/C Condenser
      • Pull securing plugs on top of radiator
      • Wiggle out from the top, swap with the new one
    • Refill Coolant, loosen bleeder screw to hasten the process
  2. Seal Secondary Air Injection
  3. Shifter Assembly
    • Install Shift Box
    • Bolt on from the top
    • Attach Sound Absorber but don't torque nuts until Selector Rod is adjusted
    • Shift Knob & Boot but don't install until Selector Rod is adjusted
  4. Clutch Line
  5. Foot pedals
    • There are a couple of different accelerator sensors depending on year, each with different connector/wiring. So if you purchase a 2nd-hand assembly remove the Accelerator pedal from it, and replace with your old Pedal & electronics
    • Clutch Position Sensor must be aligned so that sensor just engages when clutch is fully depressed
    • If not adjusted correctly the sensor will break when the clutch is pressed
    • File:ClutchSensors.JPG
    • Refill with Brake Fluid and bleed the Clutch
  6. Rear Diff
    • Process is as described in Bentley
      • Support the Diff on a Jack, and raise
      • Torque the supporting Bolts on rear frame, and the carrier on the front
    • Apply fresh CV Grease as needed to Axle CV's, keep the securing flange holes clean
    • Reattach Rear Axles, torque the Axle CV to Flange bolts
  7. Flywheel
    • Ensure the Adapter Hub on the end of the Crank shaft is removed before proceeding.
    • When removed the face of the Crank Shaft Flange should be almost flush with the rear main seal
    • Install a new needle bearing in FW
    • Always use NEW Flywheel Bolts, torque to 44Ft.lbs, that's the easy part
      • Always torque the bolts in a Star pattern, never do them sequential
      • Get a Friend ready to help do the hard part : breaker bar + 180deg
    • Rest of process is as described in Bentley
  8. Clutch
    • Be careful not to get any grease on face of Flywheel or Clutch Friction plate
    • Use the clutch alignment tool to center Friction Plate before Pressure Plate assembly is fastened
    • Don't think you need to use new Fastening bolts, just re-tighten in star pattern
  9. Transmission
    • Replace the Guide Sleeve, and lightly grease the outside with Red Moly
    • Install new Push-Out Bearing
    • Lightly (not much at all) grease the grooves at the end of the needle shaft, remove any excess grease, you don't want it to fling off onto the Flywheel & Clutch friction plate
    • Install Mounting Brackets & Shields
    • Install support RS4 Rubber Mounts
    • Install Shift selector and torque rods onto
      • Torque the selector lever onto selector shaft
      • Select an even gear (2nd, 4th) by pulling the selector rod towards rear, listen for gear engaging
        • When selecting even gear the selector lever should be almost horizontal, if not loosen selector shaft nut and adjust
      • Now push the selector rod forward to select an odd gear (e.g. 1st, 3rd)
        • When selecting even gear the selector lever should be almost vertical, it not loosen selector shaft nut and adjust
  10. Installing Slave Cylinder
    • Lithium Grease on the body of the cylinder
    • Grease on the end of the push shaft
    • Install cylinder with mounting bracket, clip the clutch line into bracket
    • Clip the clutch line into the slave cylinder, it should click, insert the retaining clip
  11. Installing Propshaft
    • Same as Bentley
    • Use the tool 3213 to hold the shaft straight before installing
    • Support in the middle with jack and raise
    • Bolt onto Rear Diff, 40 ft.lbs
    • Align shaft center bearing with mounting holes
    • Check the shaft is straight where it reaches the transmission
      • If not, the engine is mounted crooked
      • Loosen Engine Mount Bolts and Transmission Mount
      • Use Crowbar to adjust Engine position until Flange on the end of Trans lines up with Propshaft
  12. Drain and Refill the Transmission and Diff's with new Fluid
    • If EDU trans has two drain plugs, undo both, and refill to the filler plug line (not 7mm below)
  13. Adjust Shift Rods
    • In case selector shaft comes loose while adjust its better to do this before Axles are installed
    • Leave Torque Rod screw loose
    • Tighten Selector Shaft screw, find Neutral, loosen screw and adjust until Neutral is centered, retighten
      • Shift should be centered when in neutral, spring resistance should be felt moving left into 1st and right into 5th
    • Make sure can select 1st thru 5th. Then adjust Torque Rod to center position after ensuring can also select Reverse
  14. Downpipes
    • Use new Turbine-Exhaust Gaskets
  15. Exhaust
    • Re-install Heat Shields first
    • Attachment is the reverse of installation
  16. Front Axles
    • Ensure CV joints are well greased with fresh CV grease
      • If the axles are old and CV joints are stiff you can try cleaning and repacking with new grease
        • Use Axle Bolt to loosen CV, remove boot, remove balls
        • Be sure to clean off dirt/contamination with mineral spirits
        • Repack with new grease
        • Same process as replacing CV Boot
    • Loosely install Axle bolts hand tight, they will be torqued when the car is on the ground
    • Axle Heat Shields
  17. Bleed brakes
    • Follow Bentley process
    • Use Racing Blue so its easier to tell when fresh fluid is running thru whole lines
  18. Wheels
    • Install wheel bolts hand tight

Lower Car to the ground

  1. Axle Bolts
    • Use M16 Allen Key/Socket and torque to 140 ft.lbs + 180deg with breaker bar + extension
  2. Refill Coolant

Q: What you get for all this effort ? A: An extra pedal to depress

Electrical Harness

  1. Clutch Vent Valve to ECU, 2 wire connector (disables Cruise Control when clutch is depressed)
    • Connect one wire to pin 3 of the 4pin Brake Light Switch over the Brake Pedal
    • Run the other lead up through footwell and into engine bay plenum
    • Connect to Pin 39 on the ECU connector, as shown here, connected to the yellow wire
    • File:ECUHarness.JPG
  2. Clutch Position Sensor to Central Locking, 2 wire connector (disables starter until clutch is depressed)
    • Connect one wire to ground
    • Pull out pin 2 from the Blue Connector in Engine Bay Plenum
    • Connect clutch sensor lead to Pin 2
    • File:ECUConnectorPlenum.JPG
  3. Reverse Light, 2 wire connector on Transmission Right Side
    • Buy/make a harness using 2-pin connector
    • Run the harness up to grommet in the firewall next to O2 sensor brackets, and through the firewall to the ECU Box grommet
    • Left A-Pillar Brown connector Pin 8 Blue/Red wire, cut-off old lead and splice-in new wire to Reverse Sensor
    • File:ReverseLight.JPG
  4. Disconnect TCU Harness
    • Pull passenger footwell
      • Remove TCU from housing and disconnect
    • Disconnect Brown 15 pin plug in right lower a-pillar, this connects the CAN bus and K-line to TCU
  5. Remove the TCU to Transmission Valve Body and Range Selector harnesses
    • Remove brackets holding cable along side of left wheel well
    • Roll-up the cables and store safely where no electrical short-circuit
    • Seal off the ends/connectors

Reprogramming

  1. Ignition on but no start
  2. Cluster
    • Adaption, channel 60, set to 1025 (removes Transmission from CAN Bus)
    • Ignition Off
  3. ABS
    • Use Manual login code: 09495(based on state you will be recoding to)
    • Recode to 6spd : 04395
    • Ignition Off
  4. ECU
    • If recoding a Tip ECU
    • Login with 11463
    • Recode to 6spd : 06711
    • Ignition off
  5. Ignition back on
    • Clear codes in Cluster, ABS, ECU
  6. ECU Throttle Body Adaption
    • Set Block channel 60

Before Test Drive

  1. If oil was drained, pull Fuel Pump fuse, give the engine several 7s cranks, with 3s pause in between
    • Reinstall FP fuse and fire it up
  2. Let the car idle to operating temp checking & refilling coolant
  3. Make sure you can select Reverse and the Reverse Light comes on
    • If not dont force it, repeat the shift/torque rod adjustment process
  4. Instrument cluster will complain you need to depress Clutch before starting
    • Starter inhibitor switch should prevent starting until clutch is fully depressed
    • If Clutch Position Sensor is not correctly aligned, or not correctly connected to V94 then car will not start

When Test Drive is done

  1. After several miles return car to lift, recheck Trans fluid levels, adjust until fluid is 7mm below lip of the filler hole
