Product Description

The MAKITA 454317-7 is an OEM replacement connecting rod designed for use in the Makita HR4013C rotary hammer. The connecting rod is a critical internal drivetrain component that transfers motion from the crankshaft to the piston assembly, driving the hammering action of the tool.
