Your final drive is leaking oil. You can see it pooling inside the sprocket and dripping down the track frame. Every hour the machine runs, the gears inside are starving for lubrication. If you don't fix this now, you're looking at a $10,000–$15,000 final drive rebuild.
The fix is this seal. It takes 2 hours to install and costs a fraction of what a dealer charges.
A Duo-Cone (or "floating face seal") is a precision mechanical seal used in tracked equipment final drives. It consists of:
The seal sits between the rotating hub and the stationary housing, keeping gear oil inside the final drive while keeping dirt and water out.
This is one of the most universal Cat final drive seals. Verify your parts manual lists 9W-6668 or 7M-0481 before ordering.
Critical: The mating faces of the seal rings must be absolutely clean and coated with clean gear oil before assembly. Any dirt or scratches on the seal faces will cause an immediate leak. Handle the polished faces with clean gloves only.
