    As a result an inspection of the complete gearbox was required, including the production of a new output shaft. The whole inspection, overhauling, engineering and producing of the gearbox and output shaft had to be done in less then two weeks.

    Since no drawings where available, first thing done was the dismounting of the output shaft to get the shaft properties and to create a new drawing using reverse engineering. With this information the new hollow output shaft with a spline connection at the end was created in less then five days.

  • The Lohmann and Stolterfoht GPV 235 consist of a triple planetary reduction, with an output of 196 990 Nm.

    All bearings were replaced and all planetary stages where checked on cracks. It was found that none of the gears had cracks or had to be renewed.
