EXCERPT:
Disassembly Procedure
Start By:
A. Remove the implement control valve from the machine. Refer to Disassembly and Assembly, "Control Valve (Implement) - Remove" for the machine that is being serviced.
Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
1. Remove two screws and lock washers (1) from solenoid (2). Remove solenoid (2) from the control valve.
