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.

Inspection and repair on FLENDER SDN-250 gearbox

External:
- Visually check the gearbox for cracks, where possible.
- Visually checking the preservation internally and externally.
- Checking the holes for damage and dimensions.
- Checking the drillings for alignment deviations on the boring bench.
- Checking the flatness (fit) of the division planes.

Internal:
- Checking condition of the toothing of all gear transmissions.
- Checking the bearings for damage phenomena.
- Checking bearing images and flank clearance of all gear transmissions.
- Checking the shaft sizes for the bearings, oil seals, gears and couplings on dimensions and damage.
- Checking the axles for sway. - Chec

Inspection and repair on DESCH Planetaire gearbox

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
