Scope of work:

We performed an inspection and repair on a gearbox SEISA DBP 196-V.

This report presents the findings of the visual inspection and work that has been carried out during the repair of the raw mill gearbox. Immediate repair of this gearbox was required after two heavily damaged planet wheel bearings had been observed.

Despite the ordered but still not delivered replacement parts from Japan (Seisa, OEM), it was decided on the 26th of July to overhaul the gearbox and replace all rolling element bearings.

The initial inspection was carried out with the help of an Olympus videoscope. This videoscope enabled us to inspect the inaccessible planet wheel bearings.

The conversion operations consists of:

  • Inspection of the Raw Mill Gearbox
  • Repair (rolling element bearing replacement) of the Raw Mill Gearbox
  • Short and Long term recommendations
