Bosch Cylindrical Gear - 1616312004

Original Bosch cylindrical gear — part number 1616312004 — a direct-fit replacement for the gearbox of Bosch SDS‑plus rotary hammers.

This precision-machined spur (cylindrical) gear is listed in Bosch power tool parts diagrams for GBH 2‑26 variants (RE / DRE / DFR / F / E), and is also used in related GBH 2‑24 and GBH 2‑28 models, so it’s a suitable example fit when those model numbers appear on your tool.

Typical part details: straight-cut teeth (cylindrical spur gear), roughly 40 teeth with an internal bore of about 30 mm and an outer/face diameter near 50 mm — the exact gearbox position is behind the chuck/gear housing and it meshes directly in the hammer/rotation drive train.

Use this genuine Bosch component whenever worn or chipped gear teeth are causing slipping, grinding or poor hammer/rotation engagement; it’s made to drop into the original gear train and restore correct gear mesh and smooth operation.

If you need an authentic replacement listed in official diagrams, this part (1616312004) is the genuine Bosch choice from the Bosch power tool spare parts listings and fits the GBH series noted above.
