• Companion Part: The winch clutch piston this spring disc returns is R81735
• Related Parts: Clutch sealing piston ring R33248, 1st and 2nd speed piston seal R33246, piston and rod packing seal R46218, clutch input shaft bearing AT139681, side cover O-ring T51625, free spool internal oil seal AT173348
• Application: Pushes the winch clutch piston back when oil pressure is released, so the clutch disengages cleanly in the John Deere 4000 Series winch.
• Condition: Replacement Part for John Deere Equipment

Common Use Case or Symptoms: Use when the winch clutch drags or won't fully release, or when the spring discs are cracked, flattened or have lost tension — weak return springs keep the clutch partly engaged and wear the clutch pack.
