16170006EP supersedes older part numbers: 16170006D3

Genuine Bosch protection sleeve — part no. 16170006EP. This molded sleeve fits over the rotary‑hammer’s internal gear/striker area to protect the gearbox and striker shaft from dust, debris and impact wear while keeping the assembly aligned for smooth SDS‑plus operation.

Made to the original Bosch specification for a direct, drop‑in replacement, it’s a simple slide/press fit during reassembly and restores the correct clearance inside the hammer housing.

Example Bosch models this part is used with (representative, common fits): GBH 2‑20 D / GBH 2‑20 DRE, GBH 2000 (GBH 200), and GBH 18V‑20 cordless rotary hammers.

If your tool shows wear or cracking in the sleeve around the striker/gear area, replacing it with this original Bosch part will help stop accelerated wear to the gearbox and keep the hammer running to spec.
