Bosch Set Of Gearwheels - 1607000V44

1607000D4Y supersedes older part numbers: 1607000V44

Original Bosch crown gear (part number 1607000D4Y) — a direct-fit gear unit for the angle-grinder gearbox. This precision gear replaces the worn crown/gear-wheel inside the gearbox assembly (shown as position 838 on Bosch exploded diagrams) to restore correct tooth mesh and smooth power transfer to the output spindle.

Designed as a like‑for‑like replacement to Bosch specification, the unit drops into the gear housing and meshes with the bevel pinion—replace it when you see chipped or flattened teeth, grinding noise, or play in the output spindle. Example Bosch Angle Grinder models include: GWS 10‑125 C / GWS 10‑125 CE, GWS 11‑125 CIE, GWS 14‑125 (and C/CE variants), GWS 9‑125, GWS 1400, AG40‑85 (AG40‑85P / AG40‑85PD), AG50‑125PD, PWS 10‑125 CE and PWS 13‑125 CE, (Cross reference with the 10 digit product code from the side of the grinder to confirm fit before purchasing)

Sold as the single replacement gear unit (1607000D4Y). If your tool carries Bosch type numbers (for example 3601G93070) those match the same gearbox assembly that uses this part—removing the gear cover and verifying the gearbox callout on the exploded view is a quick way to confirm fit before installing. For best results, inspect the mating bevel pinion, bearings and seals while the housing is open.
