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

Power Beyond Sleeve DOES NOT work on other brands of loader control valves or products. 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.

KOYKER PART 673992 (#10 SAE External Threads –7/8”-14) includes:

• Power Beyond Sleeve-#10 SAE (K673097)
• O-ring Plug (K660669)
