Yanmar Final Drive Seal Kit 172168-73640
The Yanmar final drive seal kit 172168-73640 is a complete sealing solution for the travel motor and final drive of Yanmar mini excavators. This replacement seal kit keeps the reduction gearbox oil-tight and stops dust, mud and water from entering the travel motor housing. Engineered to OE-comparable tolerances, it installs like the original part and is a cost-effective way to restore a leaking final drive without replacing the whole assembly.
Why the final drive seal fails
- Continuous travel on rough ground wears the lip seals and O-rings.
- Dust and water ingress accelerates seal damage and oil leaks.
- A leaking seal leads to oil loss, overheating and gear wear.
