reduction gearbox oil leak

A **reduction gearbox oil leak** is the **unintended escape of lubricating oil from a reduction gearbox**.

A **reduction gearbox** is a gear assembly that **reduces input speed and increases output torque**. An **oil leak** means the gearbox lubricant is escaping from places such as:

- seals
- gaskets
- housing joints
- drain or fill plugs
- shafts or bearing areas
- cracked or damaged casing

This can lead to:

- low lubricant level
- increased wear
- overheating
- poor gearbox performance
- possible gearbox failure if not corrected
