Range Rover (LH) V8-3.5L (1987)
Checking Peak Torque
90. With the input coupling shaft toward the operator, turn the shaft fully counter-clockwise.
91. Check the torque figures obtained from lock-to-lock using a spring balance cord and torque tool R01016.
Adjustments
92. Note where the greatest figures are recorded relative to the steering position. If the greatest figures are not recorded across the center of travel (i.e
steering straight-ahead position), adjust as follows:
If the torque peak occurs before the center position, add to the shim washer value; if the torque peak occurs after the center position, subtract from
the shim washer value.
Shim washers are available in these thicknesses: 0.03mm, 0.O7mm, 0.12mm and 0.24mm (0.0015 in, 0.003 in, 0.005 in and 0.010 in).
NOTE: Adjustment of 0.07mm (0.003 in) to the shim value will move the torque peak area by 1/4 turn approximately on the shaft.
93. Fit the pitman arm to the steering box using a new tab washer. Tighten the nut to 176 Nm (130 ft lbs).
94. Refit the steering box to the vehicle.
95. Replenish the system with the correct grade of fluid.
96. Test the system for leaks, with the engine running, by holding the steering hard on full lock in both directions.
NOTE: Do not maintain this pressure for more than 30 seconds in any one minute to avoid overheating the fluid and possibly damaging the seals.
97. Road test the vehicle.
