Inspection and repair on FLENDER SDN 450 gearbox
During the inspection, a few bolt holes of the aluminum oil cooler have been rotated. This was solved on the spot by providing all four bolt holes with Helicoils. The oil cooler was then tested by raising the water pressure again, no leakages were observed.

We advise:

- Continue the vibration measurements and visual inspections at the same interval
- If a change in vibration levels, or error frequencies is detected, perform a visual inspection again
- At a subsequent revision, install a filter element in the lubrication system of the Flender KLN 250
- Adjust the axial clearance of the flexible coupling correctly.

All white metal bearings and shafts are badly damaged.

The cause for this is; the lubrication between the shaft and the bearing was inadequate.

This could be due to;

- Too much water in the oil (a lot of corrosion has been observed)
- Incorrect start-up procedure during start-up, as a result of which there is an insufficient oil film between shaft and bearing during start-up
- A combination of the above
