Recommended Maintenance Program - ABB AMG 0180 User Manual

Tools for this maintenance include the same tools as for L3, and in addition, the
rotor removal equipment. The preparations consist of opening the inspection
covers, and the removal of rotor and exciter, if applicable.
The amount of spare parts required for this level of maintenance is difficult to
determine. At least the recommended spare parts package is recommended, but
spare parts included in the capital spare part package would ensure a fast and
successful execution of this maintenance.
The Level 4 maintenance should be performed after every 80 000 equivalent
operating hour. When a L4 maintenance is conducted it replaces the L1, L2 or L3
maintenance otherwise scheduled, and it leaves their rotation unaffected, see
Table 7-1. Recommended maintenance program.
