Inspection and repair on MAAG Gs-36 gearbox

This client from Belgium came to us with this MAAG Gs-36. We inspected the gearbox and performed a repair. After a succesful testrun we shipped the gearbox back to the client.

Due to the pitting on the gears and the very rough tracks on the axial surfaces, it is advisable to renew the entire interior.

The bearings are also damaged to such an extent that they need to be renewed.

The damage seems to be caused by continuous axial forces in the gearbox. GBS suspects that this is caused by incorrect axial alignment.

Very large amount of rust has been observed in the gearbox, gears and inside gearbox.

Our advice is to;

- Clean the oil system on location, and renew the oil
- Check the alignment with respect to the axial installation dimensions.
- Check and adjust the oil system. This is to prevent the very large amount of rust in the gearbox.
