Bosch 1600A004L1 Spare Part - Armature

Replacement armature (Bosch 1600A004L1) — direct-fit, genuine Bosch rotor assembly designed to restore smooth motor operation in affected drills. The assembly includes the precision-machined shaft, copper commutator, factory-wound rotor windings and commutator segments (the rotating core that the brushes contact), rebuilt and balanced to Bosch factory tolerances so you regain torque and reduce vibration.

This original Bosch armature is listed on Bosch power tool spare parts diagrams (position 803) and is specified for the GSB 162-2 RE percussion drill family — examples include model codes such as 3601A8B000, 3601A8B060 and other GSB 162-2 RE / GSB162-2RE variants across regional suffixes.

Quick facts: part number 1600A004L1; replaces the worn or damaged rotor/commutator assembly; restores electrical contact and rotational balance; typically installed when brushes and armature show burn, scoring or open windings. Fitment and diagram references are shown by Bosch power tool parts suppliers and spares catalogs.

If your GSB 162-2 RE shows poor power, heavy sparking at the commutator, or loss of torque, this original Bosch armature 1600A004L1 is the factory replacement component specified for those models.
