Makita 141633-3 — Hammer Case Complete (original Makita replacement). This is the complete hammer/impact housing assembly used on Makita compact 18 V impact drivers and sold as part number 141633-3.
Fits examples: Makita BTD129 and DTD129 / DTD129Z / DTD129RFE), matching the factory screw bosses and mounting points for a direct fit.
What you get: the full hammer case assembly (ready to swap in) that restores the impact housing and internal mounting geometry so the hammer mechanism and gearbox align correctly — perfect when the existing housing is cracked, stripped at the screw posts, or otherwise damaged.
