Inspection and repair on PHB V-1260 gearbox

The condition of both the bearings and the toothing is acceptable, however, in order to be able to switch to long and trouble-free operation, the gearbox must be cleaned internally. The running tracks in the bearings may have been caused by rotational dirt. The observed paint chips will be transported through the oil and will cause indentations in the bearings. Impressions in the bearings will lead to locally premature surface depletion and in the long term to pitting and bearing failure.

We recommend:
- Disassemble the housing in such a way that the gear unit can be thoroughly cleaned
- Pay special attention to the lubrication system so that no paint flakes remain
-

The condition of the sand pump gearbox can be considered as good. The gears are in good condition and no major bearing damage has been observed.

Recommendations are:
- To install a breather cap with filter to prevent foreign particles from entering the gearbox
- To adjust the oil level in the gearbox according to the marks on the dipstick
- To establish a schedule of yearly visual inspections.

Inspection and repair on SEW R97-A-II2GD gearbox

Inspection and repair on HURTH HKS A 18-292 gearbox

Upon arrival, the oil had been drained from the gearbox and the cardan shaft disassembled.

After the disassembly of the coupling, the oil return channel was visible. No details were found in this, but it was blown through with compressed air and brake cleaner.

Since the gearbox was already deprived of its lubricating oil on arrival, it is not possible to retrieve it or the oil level was exceeded.

Since this gearbox is equipped with a labyrinth instead of lip seals, a too high oil level can lead to leakages.

Inspection and repair on TACKE gearbox

The condition of the three gearboxes can be considered as good, no indications of bearing damage have been observed and the toothing is in good condition.

Grooves or undulations were observed on both sides of the gears. This structure comes from the production process and not a sign of damage.
