Bosch 1607000943 — Genuine Bosch crown gear for angle grinders. This precision-machined crown gear is the gearbox driven gear used in the head of Bosch green-series angle grinders; it replaces a worn or damaged gear to restore smooth, quiet operation and correct wheel engagement. Fits many Bosch PWS-series models including PWS 550, PWS 600 and PWS 700 and related PWS6-115 / PWS8-125 variants, and other PWS angle grinders listed for this part.

Why this part: original Bosch quality and fitment ensure correct tooth profile and alignment with the factory pinion, so you won’t need extra machining or modification when swapping the part into the gearbox housing. Use it when you see metal shavings, excessive backlash, vibration or grinding noise from the gear head.

This is a direct-replacement genuine Bosch component intended for repairs — a small investment that gets your grinder back to full strength. Keep this on hand if you’re repairing grinders and sourcing power tool parts for a single repair job.
