How to repair and maintain the wheel loader gearbox - 3

Part 3: Minimizing Air Bubbles and Cavitation

During normal operation, gear oil agitation can create air bubbles within the gearbox. If these bubbles accumulate, they can reduce the effectiveness of the oil film, potentially leading to cavitation. Cavitation occurs when the oil film is disrupted, causing localized high pressures and temperatures that can damage gearbox components.

To mitigate this issue, it's crucial to use a gearbox oil with strong anti-foaming properties. This helps to minimize bubble formation and maintain a consistent, protective oil film. By preventing cavitation and reducing wear, the lifespan of the gearbox is extended, leading to fewer repairs and lower maintenance costs.
