Key Notes:

• Part Numbers: R52389
• Type: Circular thrust washer, planetary axle shaft
• Axle Compatibility: Also used in John Deere TeamMate I and TeamMate II inboard planetary axles (1200, 1400, 1600 and 1800 Series)
• Weight: 0.03 lbs (0.01 kg)
• Serial Number Notes: On the 540G, 548G, 640G and 648G, fits machines built before the serial numbers shown above. All other models listed fit every serial number.
• Application: Sits in the axle planetary and takes end thrust on the axle shaft, preventing metal-to-metal wear between the shaft and planetary components.
• Condition: Replacement Part for John Deere Equipment

Common Use Case or Symptoms: Use during any planetary or axle shaft rebuild, or when the old washer is scored, cracked or worn thin — a worn thrust washer lets the axle shaft float and wears the planetary gears and housing.

• ✅ Cheap Insurance During a Planetary Rebuild – replace it every time the planetary comes apart
