Main Control

The hydraulic system has a main control assembly. The pump assembly, hydraulic control valves and electro-hydraulic actuators are located in the main control.

Gaskets are used for the separator plate between the pump body and valve body. The separator plate between the valve body and chain cover has integral gaskets.
