Makita 221731-0 Helical Gear 45

Product Description

The MAKITA 221731-0 is a helical gear with 45 teeth, designed as an OEM replacement drive component for compatible Makita power tools and outdoor power equipment. Helical gears transfer rotational force between shafts at a smoother, quieter engagement than straight-cut spur gears, making them a common choice in higher-load gearboxes. This part is sourced directly from Makita and maintains the same geometry and tooth profile as the original factory component. Licensed technicians and trained service professionals install this type of gear during gearbox rebuilds or drivetrain repairs.

This gear is associated with Makita lawn and garden equipment based on supplier classification. It is intended for use in applications where the OEM helical gear has worn, chipped, or otherwise failed, restoring proper power transmission within the gearbox assembly. Installation requires disassembly of the gear housing and is typically performed by a qualified Makita service technician or an experienced power equipment repair professional.

Installation Notes
