How does expertise ensure reliability?
THEexpertise allows to establish a diagnostic of the device's operation.
It allows us to highlight the dysfunctions and the problems that might not be visible when the sump is closed.
How's it going ?
During the inspection, a workshop technician disassembles the device, cleans the parts, takes step-by-step photos in order to document his observations. He also carries out dimensional measurements on the different parts (sump, gears…). In certain cases, he may be required to carry out NDT inspections (magnetic particle scanning).
