Generators - BOSCH: Overhaul: Disassembly

NOTE: Due to various generator designs, the procedure for overhaul is a general outline rather than specific instructions for each type.

Remove commutator cover band and remove brushes from their holders. Remove positive brush holder screw (if equipped).
Remove both through bolts and carefully tap drive end frame, releasing it together with attached armature and pulley. Remove pulley retaining nut and pulley. Pull drive end frame with ball bearing off armature shaft.
Remove rear drive end bearing retaining screws and remove rear bearing with spacer rings and cover plate.
Clean all parts thoroughly with solvent and blow dry with compressed air. The armature windings and field cores should be blown clean and not washed with solvent.
