Scope of work:

We performed an inspection and repair on a gearbox BIERENS overhaul K8 A4-70


A client from Netherlands came to us with this BIERENS K8 A4-70 gearbox. We investigated the unit and did a total overhaul. After the revision was succesfully done, we did a test run and prepared the gearbox to be shipped back to this client.

Conclusion recommendations:

The current condition of the inspected bearing does not impede the correct and reliable operation of the gearbox. The gearbox is scheduled for a transfer in October 2016.

We have the following comments for this transfer:

- The lifting beam above the gearbox must be inspected for a minimum weight of the gearbox

- The gearbox must be completely dismantled and transported to GBS

- All bearings and seals will be replaced there and the gearbox will be inspected for further damage
