Key Notes:

  • Part Number: T173640
  • Weight: 1 lb (0.45 kg)
  • Type: ZF transmission clutch friction disc
  • Application: ZF powershift transmission clutch pack friction disc — used within the ZF transmission clutch pack on applicable John Deere wheel loaders and log skidders to transmit torque during gear range selection
  • Note: T173640 is a cross-platform disc used in both the 444/524/544 wheel loader platform and the 640–948L skidder platform — confirm your model before ordering

Common Use Case or Symptoms: Use when the ZF transmission is slipping in one or more gear ranges, clutch engagement is soft or delayed, or the transmission produces a burning oil smell — worn friction discs lose their friction surface, reducing clutch pack clamping force and causing transmission slip on applicable John Deere wheel loaders and log skidders.

Why Choose Broken Tractor:

  • ✅ Cross-Platform Coverage: T173640 fits both the 444/524/544 series wheel loader ZF transmission and the 640–948L series log skidder ZF transmission — one disc number serves both equipment families for simplified parts inventory
  • ✅ Broad Model Coverage: One disc fits seven John Deere wheel loader families and six John Deere log skidder families across multiple production generations — ideal for dealers and transmission rebuilders servicing mixed John Deere fleets
  • ✅ Fast Shipping from a U.S.-Based Team: In-stock and ready to ship from our U.S. warehouses
