Trade-Shop 183441588 - piston with striker and O-ring for Bosch GBH

Trade-Shop 183441588 - rotary hammer piston

The repair kit with a hammer piston is intended for replacing a worn impact mechanism in rotary hammers and demolition hammers. When the tool loses impact force or runs with an uneven knocking sound, a worn piston or seal is often the culprit, and replacing these parts restores performance without buying a new machine. The kit is suitable for self-repair in a workshop or on a building site, and its small size makes it easy to store spare parts.

What the kit contains

• 1 x hammer piston about 77 mm long and about 25 mm in diameter,
• 1 x striker (impact pin) about 32 mm long and about 23 mm in diameter,
• 1 x O-ring with an inner diameter of about 18 mm and a thickness of about 3 mm.

Compatibility

The replacement corresponds to the original Bosch part 1 618 700 063. The manufacturer indicates a fit for the Bosch GBH 4 DSC, GBH 4 DFE, GBH 4-32, GBH 4-32 DFR and PBH 300 E models, as well as the Würth BMH 30-E, Berner BBH 4-30, BTI BH 4-30 ME and Spit 335.
