Original Bosch hammer tube / cylinder — part number 1617000492 — a direct replacement (listed as “Hammerrohr”, item 844 in Bosch power tool parts diagrams) for Bosch demolition hammers.

What it is: a precision replacement hammer tube (cylinder) that houses and guides the piston/striker assembly in the tool’s impact chamber — a wear item that keeps the piston running true and the striker transferring full impact energy.

Fits these Bosch models (examples): GSH 16‑28 (type numbers such as 3 611 C35 000 / 3611C35000 and related variants) and GSH 16‑30 series (type numbers in the 3611C351xx ). Check the 10‑digit/type number on your tool — this part is shown for those GSH 16‑28 / GSH 16‑30 assemblies in Bosch spare‑parts lists.

Notes for the repair: supplied as the original Bosch replacement cylinder (part 1617000492) — if your machine’s exploded view shows item 844 worn or cracked, replacing this tube restores correct piston alignment and impact function. Confirm the tool’s type number before ordering.
