Original Makita Lower Head Cover — part number 454635-3. This genuine Makita replacement fits the lower head of select Makita oscillating multi-tools (notably TM3010 / TM3010C and DTM51 series) and restores the sealed cover that protects the bearing box and head assembly.
What you get: a factory-style lower head cover molded to the tool’s original shape with the correct mounting bosses and screw locations so the bearing retainer, O‑ring and balancer sit true. It prevents dust and debris from entering the head assembly and replaces cracked or worn covers that cause misalignment or vibration. If you’re buying Makita spare parts for a repair, this original Makita part is the direct, form‑fit replacement you want.
Quick fit note: intended for the TM3010 (including TM3010C) and DTM51 variants. The cover installs with the tool’s original screws and restores correct clearance around the bearing box and O‑ring.
