DESCRIPTION
Makita 227532-4 Spiral Bevel Gear 9 For HR2811FT Hammer Drill and Rotary Hammer
Description
Makita Spiral Bevel Gear 227532‑4 is a precision‑engineered drive component used in the gearbox of certain Makita rotary hammer drills (specifically the HR2811F / HR2811FT). As a spiral bevel gear, its tooth design is curved and angled, allowing the transmission of torque between intersecting shafts (at approximately a right angle) smoothly, quietly, and with high efficiency.
Function & Importance:
It transfers rotational force from the motor/drive shaft to the output (hammer + rotation) mechanism of the tool. Because of its spiral bevel design, engagement between gears is gradual, which helps reduce vibration, noise, and wear compared to straight bevel gears.
It must withstand high torque loads, impacts (hammering action), and misalignment stresses. Its hardened steel construction ensures durability under heavy use, such as drilling into concrete, masonry, or other tough materials.
If the gear becomes worn, chipped, or damaged, you may notice issues like grinding noises, reduced power, slipping or misalignment of bit rotation, increased vibration, or premature wear of other gearbox components. Replacing this gear restores proper mechanical fit, smooth operation, and maintains the service life of the tool.
