Installation - LHD
- Place the ICU in its bracket below the master cylinder. Start the upper mounting bolt to hold it in place.
- Inside the vehicle, install the remaining 2 mounting bolts attaching the ICU to the mounting bracket (Figure ). Tighten all 3 mounting bolts to a torque of 11 N.m (97 in. lbs.).
- Install the dash seal and three mounting screws (Figure ).
- Install the silencer on top of the dash seal (Figure ).
- Connect the steering shaft coupling and install the pinch bolt (Figure ). Tighten the pinch bolt to 28 N.m (250 in. lbs.).
- Install the silencer panel below the steering column under the instrument panel.
- Remove the steering wheel holder.
- Install the primary and secondary brake tubes into their correct port locations on the HCU valve block (Figure ). Tighten the tube nuts to a torque of 17 N.m (145 in. lbs.).
- Install the (4) chassis brake tubes into their correct port locations on the HCU valve block as shown (Figure ). Tighten the tube nuts to a torque of 17 N.m (145 in. lbs.).
- Install the 24-way connector on the CAB by, first, positioning the 24-way connector in the socket of the CAB and carefully pushing it down as far as possible. Once connector is fully seated by hand into the CAB socket, push down on connector lock. This will pull the connector into the socket of the CAB and lock it in the installed position.
- Install any routing clips on the brake tubes.
- Remove the brake pedal holder.
- Install the speed control servo with its mounting nuts.
- Connect the wiring harness to the speed control servo.
- Install the battery tray (Refer to TRAY - INSTALLATION ).
- Install the screw securing the coolant filler neck to the battery tray.
- Reconnect the vacuum hose connector at the tank built into the battery tray.
- Install the battery (Refer to BATTERY - INSTALLATION ).
- Install the battery shield.
- Remove the brake pedal holder.
- Connect negative cable back on negative post of the battery.
- Bleed the Base and ABS brake hydraulic systems (Refer to BRAKES - STANDARD PROCEDURE ).
- Road test vehicle to ensure proper operation of the base and antilock brake systems.
CAUTION:
Because of the flexible section in the primary and secondary brake tubes, the brake tubes must be held in proper orientation when tightened and torqued. These tubes must not contact each other or other vehicle components when installed. Also, after the brake tubes are installed on the HCU, ensure all spacer clips are reinstalled on the brake tubes.
CAUTION:
When installing the chassis brake tubes on the HCU valve block, they must be located correctly in the valve block to ensure proper ABS operation.
NOTE:
The chassis brake tube attachment locations to the HCU, are marked on the bottom of the CAB.
NOTE:
Before installing the 24-way connector in the CAB be sure the seal is properly installed in the connector.
