AirCraft AT0016-19 Gear Sleeve For Air Ratchet Wrench
At a Glance: Replacement internally splined gear sleeve that supports positive drive engagement and smooth torque transfer in the AirCraft AT0016 air ratchet.
This is the part that quietly makes “power transfer” happen. The AirCraft AT0016-19 Gear Sleeve is a replacement internally splined sleeve used in the AirCraft Air Ratchet Wrench (AT0016 series) gear/drive assembly. Its internal splines provide a positive mechanical interface that helps transmit rotation and torque through the drivetrain. If a sleeve becomes worn, rounded, cracked or distorted, the ratchet can start slipping, engaging poorly, or feeling rough under load. Replacing the gear sleeve restores a crisp, secure connection so the mechanism runs smoother and delivers torque more reliably.
Internally splined sleeves are designed for repeatable engagement under vibration and load. A good sleeve keeps the drive interface tight, reduces play, and helps protect mating gear components from uneven wear.
