Scope of work:

We performed an inspection and repair on a gearbox M.A.N. FLV 5.280x24,61.

This client from THE NETHERLANDS came to us with this M.A.N. FLV 5.280x24,61. We inspected the gearbox and performed a repair. After a succesful testrun we shipped the gearbox back to the client.

The state of both gearboxes can be considered acceptable. The bearings are in good condition with the exception of the HSS NDE bearing of SB108194, here slight degradation of the rolling elements may have been observed. However, it was not possible to inspect this sufficiently due to poor accessibility.

On the HSS NDE bearing, possible damage to the running surface of the rolling elements has been observed, possibly due to foreign particles in the oil. Although this is not a reason for action at this stage, the state of the lower should be monitored. This damage can extend to pitting, outbreak of tread and lower failure in a more advanced stage.

The observed damage images on the teeth are common in "soft" teeth, but it is advisable to carry out regular inspections because after this individual inspection (after revision) it can not be determined whether the damage pattern has stabilized.

We advise:
-Make sure that the oil pump gears receive a sufficient volume flow of oil
- Change the oil after damage to the oil pump gears
- Visual inspection of the oil pump gears in three months
- Perform a visual inspection annually.
