Idler Gear For Air Ratchet Wrench 3/8'

Overview

AirCraft Idler Gear for Air Ratchet Wrench 3/8" (AT0015-20) for Model AT0015 At a Glance: Genuine idler gear for the AirCraft AT0015 3/8" air ratchet wrench—transfer gear that helps transmit motor rotation through the ratchet drive mechanism. The AirCraft AT0015-20 idler gear is a key part of the drive train inside the AT0015 3/8" air ratchet wrench. It sits between gear stages to transfer rotation efficiently, helping the tool deliver consistent torque and smooth ratcheting action. Over time, gears can wear from heavy use, lack of lubrication, or contamination—leading to noisy operation, rough engagement, slipping, or reduced power transfer. Replacing a worn idler gear restores proper tooth engagement and helps your air ratchet run quieter, smoother and more reliably under load. Small gear, big job: clean power transfer through the head The idler gear keeps the drive train meshing correctly—good tooth contact means less noise, less heat and better torque delivery.
