CRANK SHAFT FOR AIR RATCHET WRENCH 3/8′

AirCraft Crank Shaft for Air Ratchet Wrench 3/8" (AT0015-26) for Model AT0015
At a Glance: Genuine crank shaft for the AirCraft AT0015 3/8" air ratchet wrench—critical power-transfer part for smooth engagement and consistent ratcheting.
The AirCraft AT0015-26 crank shaft is a core drive component inside the AT0015 3/8" air ratchet wrench, responsible for transferring motor power through the mechanism so you get smooth, consistent ratchet action. As the tool runs, the crank shaft works under continuous rotational load and repeated torque cycles, so wear can show up as play, rough running, slipping, or inconsistent engagement. Replacing a worn crank shaft helps bring the drive train back into proper alignment, improves power delivery, and reduces the knock-on wear that can damage bearings, gears and housings over time. If your ratchet feels loose, noisy, or uneven under load, this is one of the key parts to inspect during servicing.
The backbone of the drive train
A healthy crank shaft keeps the AT0015’s internal geometry correct—meaning smoother running, better engagement and longer life for the surrounding components.
