Procedure for Adjustment of Parking Brake

1. Place parking brake lever (16) in the down position (brake ON). Adjust rod (15) until the rod fits freely in lever (16) .

2. Tighten locknut (14) on rod (15) to a torque of 5.0 ± 0.5 N·m (45 ± 5 lb in) .

3. Pull up on lever (20) until resistance is felt. Adjust rod end (18) until pin (17) fits freely in the rod end. Shorten rod assembly (19) by turning rod end (18) down two full turns.

4. To check the parking brake adjustment, install a 0 to 4000 kPa (0 to 600 psi) pressure gauge on the right or the left brake pressure tap.

5. Start the engine and run the engine at LOW IDLE .

6. Place parking brake lever (16) in the ON position. While the parking brake is ON the pressure gauge must read less than 300 kPa (44 psi). If the pressure is not less than 300 kPa (44 psi), make rod assembly (19) shorter and check the pressure again.

Procedure for Adjustment of Transmission Control Linkage

1. Place shift lever (13) in position, as shown. The control lever must be centered in the slot. See view (A-A) of illustration 1 .

2. Position lever (23) in NEUTRAL. Lever (23) is on the transmission valve for speed control. See detail B of illustration 1. Adjust rod end (9) on rod (5) until the stud fits freely into rod end (9) . Adjust rod end (9) on rod (5) until bolt (1) fits freely into lever (2) .

3. Position lever (24) in FORWARD (F). Lever (24) is on the transmission valve for direction control. See detail B of illustration 1. Adjust rod (6) for a free fit of bolt (3) in lever (4) . Adjust the rod until bolt (8) fits freely in rod end (7) .
