Bosch 1617000711 Spare Part - Hammer Piston

1607000C3M supersedes older part numbers: 1617000711

Genuine Bosch 1607000C3M — hammer piston / piston-rod assembly designed to restore impact performance in Bosch demolition hammers. This precision-machined piston transfers the striker energy through the cylinder and is the replacement part shown in the Bosch power tool parts diagram (position 892), made to the original fit and tolerances you need when repairing a heavy-duty breaker. It’s most commonly used in the GSH 16-28 series and also fits GSH 16-30 variants (multiple regional model codes), so it’s a direct-fit option if your GSH 16‑28 or GSH 16‑30 has a worn or damaged piston. Many listings show the assembly supplied with the piston and sealing O‑ring, ready to drop into the front cylinder during a routine repair. If you’re buying individual power tool parts to get a hammer back to service, this genuine Bosch piston gives the correct geometry and factory-level fit for those demolition hammers.
