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.
