Procedure for Adjustment of Transmission Control Linkage
1. Position shift lever (14) as shown in View A-A (centered in slot)
2. Position lever (9) at transmission valve for speed control in neutral (shown in detail C) and adjust rod (16) for free fit of bolt in lever (18).
3. Position lever (10) at transmission valve for direction control in forward (shown in detail C) and adjust rod (15) to obtain a free fit of bolt in lever (17).
Procedure for Adjustment of Parking Brake
NOTE: While the Type 1 and Type 2 linkages look somewhat different, the adjustment procedures are the same.
1. With parking brake lever (4) located as shown in the brake ON position (lever down), adjust rod (2) until end fits freely in lever (4).
2. Tighten locknut on rod (2) to a torque of ... 5 ± 0.5 N·m (4 ± .5 lb ft).
3. Adjust rod assembly (5) to the specified length. Install the adjusted rod assembly.
NOTE: Do not change the length of rod assembly (5) in further adjustments.
4. Disconnect rod assembly (8) at its upper end.
5. Pull up on lever (13) until resistance is felt. Do not stretch spring can on rod (8) if so equipped. Adjust the length of rod assembly (8) until pin fits freely through upper rod end (7). Then turn upper rod end (7) down two full turns (shorten) and install rod assembly (8).
6. To check parking brake adjustment, install a 0 to 4000 kPa (0 to 600 psi) pressure gauge on either the right or left brake pressure tap.
7. Start the engine and run it at low idle.
8. With parking brake lever (4) in the brake ON position (lever down), 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 (8) shorter and check the pressure again.
9. Rotate parking brake lever (4) to the brake OFF position (lever up). The pressure gauge must read 2750 ± 150 kPa (400 ± 22 psi). If the pressure reading is low, make rod assembly (8) longer and check the pressure again.
10. After adjusting the linkage in Steps 8 and 9, attach a 0 to 4000 kPa (0 to 600 psi) gauge to the P1 pressure tap on the transmission. With the engine running at low idle, move parking brake lever from brake ON to brake OFF (full lever travel each way). The P1 pressure should read exactly the same with the parking brake ON or OFF.
11. If the P1 pressure is not the same with the parking brake ON as it is with the parking brake OFF, the parking brake valve is leaking oil and the linkage must be adjusted further using the following instructions:
A. If P1 with the parking brake OFF is less than P1 with the parking brake ON, lengthen rod assembly (8).
B. If P1 with the parking brake ON is less than P1 with the parking brake OFF, shorten rod assembly (8).
12. If linkage adjustments are made in Step 11, repeat the pressure checks in Steps 7, 8, and 9. Readjust as necessary until all pressures are met.
