Load Compensator: Testing and Inspection

1. Drive vehicle onto a hoist or alignment machine, so that vehicle is at curb load level and wheels are on a flat surface. Make sure fuel level is at least 3/4 full.
2. Loosen valve adjuster setscrew.

NOTE: Do not change position of the upper nut on valve operating rod.





3. Obtain a piece of rubber or vacuum hose or plastic tubing 3/8-inch OD x 1/4-inch ID. Cut a piece 16.3 mm ± 0.3 mm (0.64 ± 0.012 inch) and slice it lengthwise.
4. Place hose or tubing on valve operating rod.
5. Make sure the adjuster sleeve is resting on the lower mounting bracket and not corroded to the rod. It must move freely when the set screw is loosened. Install setscrew. The dimension will position the valve for normal operation. Remove hose or tube.
6. Alternate adjustment / check method: Set an inside vernier caliper to 16.3 mm (0.64 inch) and insert between the nut and grommet. Perform adjustment as above.
If further adjustment is necessary, proceed to step 7.





7. To decrease pressure at rear brakes install setscrew in adjuster sleeve in desired position.
To increase pressure at rear brakes tighten setscrew in desired position.
