Inspection and repair on ZPMC gearbox

GBS has been instructed to find the cause of abnormal vibrations and strange noises from gearboxes. The complaints are described as follows:

"Gearbox gives great vibration which is easily felt in the floor" "2nd cat hoist has a separate sound, possibly with input shaft or first stage"

We recommended:

- Ensure that the gear units are filled with the correct amount of oil, for example by fitting new oil level glasses
- To be able to detect the development of a damage on time every three months to perform a vibration measurement
- Carry out a yearly visual inspection (and increase the vibration levels or detection of error frequencies).

- 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
