Load Compensator: Testing and Inspection

LOAD SENSING SPRING LENGTH CHECK AND ADJUSTMENT
1. Park the vehicle on a level ground. The vehicle should be unloaded and supported only by wheels.

CAUTION: Never support the vehicle with jacks or other similar means.





2. With the lever pressed all the way to the load-sensing proportioning valve side, check whether the length of the spring (the length between its ends) shown in the illustration is at the standard value.
Standard value: 224 - 228 mm (8.8 - 9.0 inch)





3. If the spring length is not within the standard value, loosen the bolt attaching the support and adjust the distance by moving the support.
