Final drive leaking gear oil: what replacement fits my machine?

Expert Answer

A final drive leaking gear oil usually points to a failed seal, worn bearings, or damage around the gearbox or motor housing. If the leak is heavy or the oil looks contaminated, the safest move is to stop running the machine until it is inspected, because low oil can quickly damage the final drive.
