Original Makita 157640-6 — Gear housing for the JS3200 metal shear. This molded gear housing locates the crankshaft, needle bearing and gear train, and mates to the gear-housing cover (part 156833-2) so the internal gears run true again. It’s the direct replacement housing listed for the JS3200 (also referenced in parts diagrams for the JN/JS3200–JS3201). Perfect when you need a single replacement part to get a Makita shear back to service — ideal for anyone sourcing power tool parts to repair a damaged gearcase. Order this original Makita housing when your JS3200’s casing is cracked, stripped at the screw bosses, or no longer holds the bearings and shafts securely.
