When you’re noticing gear oil spots under your tractor or hearing unusual noises from the final drives, there’s a good chance the sealing washers in your planetary housing need attention. This small but critical sealing washer keeps expensive gear oil where it belongs and prevents contamination from destroying your costly planetary gear assembly. It’s one of those little parts that saves you from big repairs down the road.
What You’re Getting
- Precision-manufactured washer designed specifically for your John Deere’s operating pressures and temperatures
- Keeps contamination out while maintaining proper lubrication for planetary gear components
- Updated materials that resist breakdown from modern gear oils while maintaining flexibility
- Direct replacement that fits properly without modifications or special tools
Built for Real Farm Work
Your John Deere tractors rely on their final drives for legendary durability, powering through demanding tasks from heavy tillage to high-speed road transport. The 4WD systems on modern tractors represent significant investments with complex differentials and planetary reductions at the wheels – this simple washer protects all these components.
Made to Last
This sealing washer prevents two types of catastrophic failure – keeping expensive gear oil from leaking out and blocking water and contamination from entering. Built to handle the constant flexing and heat cycles that these seals endure, catching problems early saves major repair bills.
Installation Notes
Clean the housing thoroughly and inspect for wear before installation. Use proper tools to ensure even seating and pre-lubricate with clean gear oil. While you have it apart, check bearing preload and planetary gear condition – a leaking seal often indicates other wear issues that need attention.
