Load Compensator: Adjustments

Height Sensing Proportioning Valve:

NOTE: After installing a new height sensing dual proportioning valve, bleed both hydraulic circuits at rear brakes.

CAUTION: The rubber stone/snow shield must be installed when ever the valve is serviced. The shield protects the valve and hydraulic lines from stone impact and the packing of snow and slush.
