The state of the gearbox is rated as good. No significant damage has been found. The wear images of the various parts are fine.

- The observed foamy substance is probably the result of saponification of the oil, this is a chemical reaction of water with oil. The presence of water in the oil is probably caused by poor ventilation in combination with a low operating temperature.

Recommendations:

- It is recommended to change the oil and remove the foamy substance, and to check the air filter.
- It is recommended to perform a visual inspection every year.
