This part is a genuine manufacturer-sourced part, which is specially designed for Makita drills. The gear assembly is an important component to your cordless drill. It consists of the clutch, transmission, and a hammer drill mechanism. The most common symptom that your gear assembly is going bad is that the motor spins, but the chuck does not. When this happens, you will usually hear grinding noises from the transmission at the same time. However, before replacing the gear assembly make sure the gear selector isn't moved between the high and low gears, if so your drill will display the same symptoms. The following tools are required for the repair: torx driver, Phillip's screwdriver, long-nosed pliers, large screwdriver, hammer, large Allen wrench and small screwdriver. This part is sold individually and is made of metal and hard plastic.
