	Measure
1	Remove rotor (7)	Only if there is severe contamination:	AR43.40-D-1600C
2	Clean rotor (7) and pole flanges (8) using wire brush	Only if there is severe contamination:
3	Install rotor (7)	Only if rotor (7) was removed because of severe soiling.	AR43.40-D-1600C
4	Use feeler gauge to measure gap widths at six points on the rotor (7) and the pole flange (8) opposite	When doing so, start at measuring point 1 (1) and determine the dimensions while working your way up to measuring point 6 (6). The corresponding feeler gauge must be able to be pulled through between the rotor (7) and pole flange (8) on the stator with a slight resistance.
		Gap between rotor and stator	*BE43.40-N-1001-01C
5	Calculate mean value from the six measurement values per rotor (7)	If the mean value is out of tolerance, the gap width must be adjusted on the corresponding rotor (7): ↓	*BE43.40-N-1001-01C
		Adjust gap	AR43.40-D-1400C
