Original Makita 312956-8 — Rod
Restore the piston-to-crank connection with this genuine Makita 312956-8 rod, the factory part used in Makita demolition and rotary hammers. It’s the internal connecting rod listed in Makita parts breakdowns (positioned directly with the piston, needle bearing 212108-0 and crank shaft), so it installs where the piston’s motion is transferred to the crank assembly.
Fits (examples): Makita HM0810 (and HM0810 variants) and Makita HR3850 / HR3850B / HR3850K, and HR3851.The HR3850/HR3851 series is the 38 mm (1-1/2") rotary-hammer class, so this rod is the correct internal crank/piston link for those tools.
Notes for installation: the part is shown in the official Makita parts breakdowns as “ROD” and is paired with needle bearing 212108-0 and the crank components in the same assemblies — check your tool’s parts diagram for the matching item number and orientation before installing. This is the original Makita part number used in Makita service literature.
(If your model is one of the HR3850/HR3851 or HM0810 variations, this is the rod called out in the Makita parts diagrams for those models.)
