A general overhaul of the motor must be carried out every 5 years.

For this the motor must be dismantled. The following work must be carried out:

• All components of the motor must be cleaned

• All components of the motor must be examined for damage

• All damaged components must be replaced

• All roller bearings must be replaced

• All seals and shaft sealing rings must be replaced

• Measure the insulation resistance

The general overhaul must be carried out by qualified personnel in a specialist workshop with

appropriate equipment. We strongly recommend that the general overhaul is carried out by

NORD-Service.
