950H Wheel Loader, 962H Wheel Loader and IT62H Integrated Toolcarrier Electrohydraulic System Caterpillar

Use the following procedure in order to change the pressure equalization time of the ride control system.

The pressure equalization time for the ride control is the transition between OFF and ON. This transition is the time that is required to equalize the pressure between the ride control accumulator and the lift cylinders.

Note: When the ride control system is activated and the pressure between the accumulator and the lift cylinders is not equal, the lift arms will raise depending on the load or the lift arms will drop.

The factory setting of pressure equalization time for the 950H and 962H Wheel Loader is 3 seconds.

The ride control system changes from OFF to ON more quickly when a lower value is entered. Likewise, the transition of the ride control system from OFF to ON is slower when a higher value is entered. For example, setting the time to a greater value will result in more time in order to balance the accumulator with the lift cylinders. Now, more time is required for the ride control system to go from OFF to ON after the switch is placed in the ON position. The ride control system requires more time to equalize when the hydraulic oil is cold.
