317814-3 supersedes older part numbers: 317814-3
Original Makita gear housing — part no. 317814-3. This is the genuine Makita gearbox/gear housing (the metal gearbox head that houses the spindle, gears and bearing seats) used on Makita’s compact angle-grinder; it replaces a damaged or cracked gearbox shell and restores correct alignment for the spindle and bearings so the grinder runs true.
Compatibility examples: fits a range of Makita angle grinders — commonly listed for models such as 9553NB, 9554NB, 9555NB and the 9557NB / 9558NB . Use this part where the original gear housing is broken, stripped at the handle/guard threads, or leaking lubricant from the gearbox.
Notes for fit and use: this is the replacement gear housing item from Makita and is designed to accept the grinder’s original spindle assembly, bearings, guard and auxiliary-handle mounting points — simply swap the worn housing for the 317814-3 and reassemble per the tool’s parts diagram. If you need the housing alone (not a full gearbox assembly), this part is the housing specified by Makita’s parts lists.
