Koyker Part 673992 (No. 10 or 5/8” O-ring port)

If used on a tractor with a closed center hydraulic system, adding a power beyond sleeve and a plug converts the loader control valve to a close center valve.

If used as a power beyond, adding this and a hydraulic hose on an open center system will reduce back pressure and maintain hydraulic oil flow to the 3 point hitch and selective control valve.

    • Does power beyond sleeve 673992 replace 673097?

      Thank you for reaching out!

      The K673992 includes K373097, plus a plug that screws in the top of the K673097 power beyond sleeve to make the valve a closed center valve, like for a John Deere. For open center tractors, you don’t use the plug, just the K673097 sleeve.

      Our customer service team can be reached at 1-800-557-4689 or 1-605-336-1750 if you did want to verify parts needed prior to making any purchases. Thank you.
