Metabo 316063640 Spare Part - Gear housing compl.

Original Metabo 316063640 — Gear housing complete (gearbox shell). This genuine Metabo spare part is the complete gearbox housing used on several small angle grinders and compact grinders; it replaces a cracked, stripped or misaligned housing to restore correct bearing seating and gear alignment.

Fits example models such as W 850-125, W 850-115, W 750-115, W 85100 and other W-series small angle grinders where Metabo lists part 316063640 as the gear housing assembly. Confirm fit for your exact model, but these are the most common machines that use this housing.

Key details: this is the complete gear-housing assembly (not just a cover) with built-in bearing seats and mounting bosses designed to accept ball bearings sized 8 × 22 × 7 mm and 6 × 19 × 6 mm and to work with an M14 spindle. It is designed to mate with the matching flange assembly (e.g., part 316063780) and the bevel gear/pinion set used in the W-series grinders.

Why choose this part: using the original Metabo 316063640 gear housing keeps factory tolerances for bearing alignment and spindle runout, helping prevent premature wear of gears and bearings and restoring safe operation of your grinder. The housing is the same type used by Metabo on their compact grinders and shares the robust construction their product pages describe.

If your grinder’s gearbox is cracked, stripped or the bearing seats are damaged, this original Metabo gear housing is the direct replacement designed to bring your tool back to proper mechanical alignment.
