Description
Overview:
The Spiral Bevel Gear 37 is a genuine Makita part designed for the drive train of Makita rotary hammer drills, including the HR3210C and HR3540C. Built from hardened steel, it transfers power smoothly between the motor and hammer mechanism, helping to maintain efficient rotation, torque, and tool longevity. As a direct-fit service component, it replaces a worn or damaged gear to restore performance and prevent further wear to mating parts. Manufactured to factory tolerances and identified by Makita part number 227531-6, it meshes accurately with the matching pinion to reduce stress on bearings and extend service life. This gear is suitable for workshop overhauls and on-site repairs where reliability and durability are essential. Genuine Makita Part for assured compatibility.
