Scope of work:

We performed an inspection and repair on a gearbox ASUG GVE 800x3,75-800x0,4.

This client from The Netherlands came to us with this ASUG GVE 800x3,75-800x0,4. We inspected the gearbox and performed a repair. After a succesful testrun we shipped the gearbox back to the client.

This page presents the overhaul of the propulsion gearbox’ PTO shaft, on board a ship. GBS was invited to perform the overhaul, following the initial inspection by GBS. The overhaul of the PTO shaft as described in this report, was carried out successfully. Bearings were replace and axial clearance re-adjusted. A test-run was finally carried out, showing no abnormalities in vibration, sound and temperatures.

The repair of the gearbox should however be considered as a temporary solution. As of a consequence of the diagnosed bearing damage, both bearing pockets showed severe (old) rotation marks.

In order to guarantee proper operation of the gearbox, it is recommended to:

- Carry out a complete inspection & overhaul of the gearbox
- Recondition both bearing pockets (by lasercladding or rebushing
- Check alignment of the generator & gearbox
- Continue annual visual inspections, vibration measurements and oil analyses
