Service Magazine SEPD1162, 06 August 2010, "Improved Control Valve Group Available for Certain Compact Track Loader, Multi Terrain Loader, and Skid Steer Loader Machines". Disregard the existing article. Refer to the following information.

Description of Change: A new control valve group is available for certain Compact Track Loader, Multi Terrain Loader, and Skid Steer Loader machines. The new control valve group utilizes new screened solenoids that reduce the amount of contamination that may flow into the solenoid.

Adaptable To:

Table 1

New Control Valve Part Number	Description	Former Control Valve Part Number
336-1325	Control Valve Gp	258-2509
336-1324	Control Valve Gp	258-2508
336-1323	Control Valve Gp	258-2507
336-1322	Control Valve Gp	258-2506
336-1317	Control Valve Gp	216-6167
336-1321	Control Valve Gp	191-9686
336-1320	Control Valve Gp	216-6170
336-1319	Control Valve Gp	216-6169

Table 1 provides the part number for the new control valve groups that contain the screened solenoids and the former control valve part number. The new valve groups will need to be serviced with the new screened solenoids. The old valve groups will need to be serviced with the old solenoids.

Note: When replacing the complete control valve group, the machine ECM will need to be flashed with the latest machine software version available for that model.The new control valves are adaptable to the following serial numbers:
