M.A.N. 08-208 gearbox Inspection and repair service

Scope of work:

We performed an inspection and repair on a gearbox MAAG Gs-22.

We got this MAAG Gs-22 in our plant in October 2016 from Belgium clients. After doing a test run, we shipped the gearbox back to our client.

Scope of work:

Releasing the internal preservation and finding white metal chips is a cause for concern. If the machine should be restarted in this condition, serious damage can occur to the bearings and the gears. Reliable operation of the gearbox cannot be guaranteed.

It is advisable to send the gearbox complete to GBS: The following must then be viewed / done in the workplace:

- The reason for releasing the interior preservation of the cabinet and repairing it
- The condition of all white metal bearings; - The condition of the pinion on the input shaft (towards the pump) and an explanation for the light gray spots on this gear
- Provide an explanation for the co-turning track on the inner axially lower cheek of the input shaft
- The state of the teeth in the displacement pump
- Record the axial, flank and radial spellings of all parts in the cabinet
- Determine the dimensions of all bearings, shaft dimensions at the bearings
- Check this value with the measured values ??from before dismantling
- Also check the value again after mounting
- Make a detailed report of the revision carried out.
