Load Compensator: Testing and Inspection

ON-VEHICLE INSPECTION

HINT: Pre runner is the described below.
RZN191L-TRPDKAB, RZN196L-CRPDKAB, VZN195L-RPDKAB





1. SET REAR AXLE LOAD





Rear axle load (includes vehicle weight):





2. INSTALL LSP & BV GAUGE (SST) AND BLEED AIR
SST 09709-29018





3. RAISE FRONT BRAKE PRESSURE TO 7,845 kPa (80 kgf/cm2, 1,138 psi) AND CHECK REAR BRAKE PRESSURE





Rear Brake Pressure:

HINT: The brake pedal should not be depressed twice and/or returned while setting to the specified pressure. Read the value of rear brake pressure 2 seconds after adjusting the specified fluid pressure. If the brake pressure is incorrect, adjust the fluid pressure.





4. IF NECESSARY, ADJUST FLUID PRESSURE
a. Adjust the length of the No. 2 shackle.
Low pressure - Lengthen A
High pressure - Shorten A





Initial Set:





Adjustment Range:

HINT: One turn of the nut changes the fluid pressure as shown in the following table.





Rear Brake Pressure:





b. If the pressure cannot be adjusted by the No. 2 shackle, raise or lower the valve body.
Low pressure - Lower body
High pressure - Raise body
c. Torque the nuts.
Torque: 13 Nm (130 kgf-cm, 9 ft. lbs.)
d. Adjust the length of the No. 1 shackle again. If it cannot be adjusted, inspect the valve housing.





5. IF NECESSARY, CHECK VALVE BODY
a. Assemble the valve body in the uppermost position.

HINT: When the brakes are applied, the position will move down about 0.8 mm (0.03 inch). Even at this time, the piston should not make contact with or move the load sensing spring.





b. In this position, check the rear brake pressure.





If the measured value is not within the standard, replace the valve body.
