Special Instruction, SEHS0084, "Replacement Procedure of the Solenoid Coil Assembly in the Solenoid and Relief Valve Group on Certain Excavators and Mobile Hydraulic Power Units"

The solenoid coil assembly of the 335-0084 Solenoid and Relief Valve Gp has been improved and is more durable. The improved 458-5907 Coil is now serviced instead of replacing the whole valve group. If the solenoid coil needs to be replaced, refer to Special Instruction, SEHS0084. The part number for the 335-0084 Solenoid and Relief Valve Gp has not been changed. The valve group with the improved solenoid coil assembly can be identified by the stamp on it. If there is no stamp, the valve group is not the improved part.
