Description of Change: A new connector is added to the P port of various valve groups. The new connectors have a filter that prevents debris from entering the P port. Preventing debris from entering the port will help eliminate spool sticking and increase the service life of the valve.

Adaptable To: Machines in production will have the new connector with filter installed. Table 1 lists the new parts and former parts for those existing machines in the field. Refer to Special Instruction, REHS5634, "Rework Procedure for Connector With Filter Addition for All Excavators"
