1617000A4W supersedes older part numbers: 1617000V75, 1617000A4W

Genuine Bosch motor housing, part 1617000A4W (also listed as 1 617 000 A4W) — a direct-fit motor/case assembly designed to replace the damaged casing on compatible 36 V rotary hammers.

This molded motor housing protects the armature and electronics, provides the factory mounting bosses for the switch and handle, and matches the original Bosch fit and alignment so the tool reassembles to factory tolerances.

Example fitment: Bosch GBH 36 V‑LI / GBH 36 VF‑LI and related 11536VSR 36 V rotary‑hammer type models (check the tool’s 10‑character type number against your parts diagram).

Sold as the single motor housing (position 801 on the GBH‑36 exploded diagrams), this original Bosch replacement is one of the essential power tool parts to restore structural integrity and proper cooling of the motor.
