• Release the brake disc’s companion flange by first removing the locking ring together with the washer in the end of the rotor shaft. The companion flange can now be lifted off. It may be necessary to unclamp it with an appropriate tool. • Remove the four plugs that cover the carbon brushes, move the springs on the carbon brushes to one side and pull out the carbon brushes. • Dismantle the commutator end’s bearing shield (2) together with the carbon brush bridge (5) and carbon brushes (8) by unscrewing the eight screws (1). Now put down the motor with a firm resting point against the edge of the bearing shield, and carefully tap on the rotor shaft’s end with a rubber mallet. • Dismantle the drive end’s bearing shield (15) together with the rotor (9). Make sure not to damage the motor windings when the rotor is removed from the motor housing. • After dismantling the motor’s bearing shields and removing the rotor from the motor housing, the gear wheel in the rotor’s drive end is removed. This is done by unscrewing the nuts on the gear wheel and then pulling the gear wheel off with a puller. Note that the gear wheel is locked with Loctite to the rotor shaft. • Now release the inner locking ring together with the underlying washer. Pull out the rotor shaft from the bearing (18). 7- 4
