Description
When transmission oil starts showing up in spots under your tractor or you notice the drop box making more noise than usual, it’s probably time for a new shaft seal. This seal sits in the drop box housing where the transmission shaft passes through, keeping gear oil where it belongs while dirt and moisture stay out. It’s one of those parts that works quietly until it doesn’t—and then you’ve got a mess on your hands.
What You’re Getting
- Precision 44.4 x 63.5 x 12mm dimensions for exact fit in your drop box housing
- Durable seal materials that handle the heat and pressure of transmission fluid
- Single-lip design that creates a tight seal around the rotating shaft
- Direct replacement that installs just like the original equipment seal
Built for Real Farm Work
This seal works across a wide range of John Deere models from the smaller 5020 series utility tractors through the 6000, 6010, 6020, and 6030 series that are the backbone of many farming operations. These tractors handle everything from row-crop farming to livestock operations, and they need reliable seals to keep their transmissions running smoothly season after season.
Made to Last
Modern seal materials resist the heat and chemicals that destroyed older designs. This seal is built to handle the temperature swings and fluid pressures that come with hard farm work, from cold morning startups to long days in the field.
Installation Notes
Before installation, thoroughly clean the seal bore and inspect shaft surfaces—even minor grooves cause rapid seal failure. Use proper seal drivers to avoid lip damage and apply light coating of gear oil to seal lips before installation. While you’ve got things apart, check your transmission fluid level and condition—contaminated oil can tell you if the seal’s been leaking for a while.
