(3) Final torque for the nut ... 47 ± 9 N·m (35 ± 7 lb ft)

(4) Torque for the bolt ... 47 ± 9 N·m (35 ± 7 lb ft)

(5) Apply 1P-0808 Grease to the shaft prior to assembly.

(6) Torque for the nut ... 12 ± 3 N·m (106 ± 27 lb in)

(7) Torque for the two bolts ... 47 ± 9 N·m (35 ± 7 lb ft)

(8) Final torque for the two screws ... 47 ± 9 N·m (35 ± 7 lb ft)

(9) Final torque for the two nuts ... 47 ± 9 N·m (35 ± 7 lb ft)

(16) Torque for the bolt ... 47 ± 9 N·m (35 ± 7 lb ft)

(18) Apply 1P-0808 Grease to the shaft prior to assembly.

Adjustment Procedure

  1. Set the distance from pin (17) to pin (1) by adjusting the rod (2). The distance should be equal to 108 mm (4.3 inch).

  1. Dimension (A) should be 137.2 mm (5.40 inch). Adjust screw (8) in lever (15). A 0.5 ± 0.3 mm (.02 ± .01 inch) gap should be between the screw (8) and lever (21) .

  1. After the cable is attached, adjust screw (8) in lever (19). A 0.5 ± 0.3 mm (.02 ± .01 inch) gap should be between the screw and lever (20) .

Adjustment for the Stop Lamp Limit Switch

  1. With the brake valve in the OFF position, bring switch (11) into light contact with the surface of the ramp. The brake valve is in the OFF position when stem (10) is fully out.

  1. Move bracket (12) by 2.75 mm (.108 inch) toward the panel. Moving the bracket will depress the switch to the OFF position.

(13) Torque for the bolt ... 47 ± 9 N·m (35 ± 7 lb ft)

(14) Torque for two bolts ... 80 ± 4 N·m (60 ± 3 lb ft)
