327142-8 supersedes older part numbers: 326376-0
Original Makita crank shaft (part no. 327142-8) — a precision-machined, hardened-steel crankshaft engineered for SDS‑MAX rotary hammers. This genuine Makita replacement features accurately finished journals and bearing surfaces for smooth piston-to-rotary motion, and is supplied as the single crankshaft component ready to install in the gear/barrel assembly.
Fits Makita HR5212C and compatible HR5202C 52 mm class rotary hammers (the 327142-8 crankshaft is the repair part listed for these models). It corresponds to Makita’s parts listings for those HR52-series models and replaces the earlier crank-shaft designation used in the service parts diagrams.
