Description
Overview:
This Genuine Makita crank shaft (part no. 324839-0) is a precision internal component for rotary hammer drills in the HR32 and HR35 series, including HR3210 and HR3540. Made from precision-machined steel, it converts motor rotation into the hammering action required for fast, consistent drilling and chiselling in concrete, masonry, and similar hard materials. Replacing a worn or broken crank shaft restores the tool's impact performance, reduces vibration from imbalance, and helps prevent further wear to mating parts in the hammer mechanism. Designed to match factory specifications, it is a reliable, direct replacement that maintains the original performance and service life of your Makita hammer drill. Ideal for both professional site work and serious DIY maintenance where dependable impact energy and smooth operation are essential.
