Makita Chuck Cover — part 417027-7 — original Makita replacement designed to restore the front housing around the chuck / tool‑holder on compatible rotary hammers. This molded cover protects the chuck assembly and nearby seals from dust and debris and installs quickly using the tool’s existing mounting points (mounted with tapping screws per the parts diagram).
Designed for the HR3000C , the part matches the factory mating surfaces and fastener locations so it snaps / bolts into place without modification. If your tool has a damaged or missing cover that leaves the chuck, O‑rings or spring guides exposed, this genuine Makita replacement returns the unit to correct form and fit.
It uses the same four tapping screws (5 × 30 mm) shown on the exploded parts diagram and aligns with the chuck ring, spring guides and seal case for proper reassembly. Useful when repairing with original Makita parts rather than adapting other components, it’s a simple swap that gets your rotary hammer back to reliable service.
