The hammer case is the tough outer shell that holds and protects the impact mechanism—taking the knocks, containing the grease, and keeping everything aligned so the hammer can strike properly.

AirCraft Air Impact Wrench Service Kit – Bearings (15 & 22) for AT0004 (AT0004-SK03) At a Glance: Bearing replacement kit for the AirCraft AT0004, supplying the two key bearings (reference 15 and 22) that support smooth, stable rotation.

The AirCraft AT0004-SK03 bearing service kit replaces the tw..

AirCraft Air Impact Wrench Service Kit – Hammer Frame & Bushing (10–13) for AT0004 (AT0004-SK04) At a Glance: Impact mechanism support kit for the AirCraft AT0004, including hammer frame components, bushing and pins to keep the hammer assembly running true. The hammer frame is the “skeleton” that supports the impact mechanism inside your wrench. It keeps the hammer components aligned, guides movement, and ensures the impact energy transfers cleanly to the drive. When the frame or bushing wea..

AirCraft Air Impact Wrench Service Kit – Rotor & Cylinder (16 / 17 / 19–21 / 24) for AT0004 (AT0004-SK05) At a Glance: Air motor core rebuild kit for the AirCraft AT0004 including rotor and cylinder components to bring back smooth, efficient power delivery. When an impact wrench feels weak, slow to spool up, or rough under load, the air motor is often the culprit. The rotor and cylinder form the core of that motor—where air pressure is converted into rotation. If these surfaces are worn or s..

AirCraft Air Impact Wrench Service Kit – Housing & Valve (25–28 / 37 / 40) for AT0004 (AT0004-SK06) At a Glance: Main housing and air-control valve service kit for the AirCraft AT0004, designed to restore sealing, fitment and smooth trigger/airflow control. The housing is the backbone of the tool—holding the motor, impact section and handle together—while the valve system controls airflow, direction and trigger response. If the housing is damaged, threads are stripped, or the valve parts are..

AirCraft Air Impact Wrench Service Kit – Reverse Valve (35–36 / 38–39) for AT0004 (AT0004-SK07) At a Glance: Reverse valve service kit for the AirCraft AT0004 with springs and detent components to keep the forward/reverse selector crisp and leak-free. The reverse valve is what lets your impact wrench swap direction—forward to tighten, reverse to loosen—by rerouting airflow inside the motor. When the reverse valve components wear, the tool can feel vague when switching direction, slip out of ..

AirCraft Air Impact Wrench Service Kit – Throttle & Valve Stem (29–34) for AT0004 (AT0004-SK08) At a Glance: Throttle/trigger valve service kit for the AirCraft AT0004 including spring, valve seat/cap and sealing O-ring to restore smooth air control. The throttle valve is the “tap” that controls how much air enters your impact wrench when you pull the trigger. If the valve stem or seat is worn, or the spring and seals are tired, you can get air leaks, a sticky trigger feel, weak power delive..

AirCraft Air Impact Wrench Service Kit – Rotor Blades Only 6pc Set (18) for AT0004 (AT0004-SK09) At a Glance: 6-piece rotor blade (vane) set for the AirCraft AT0004 air motor—an essential refresh for power, efficiency and smooth rotation. Rotor blades (also called vanes) are the wear items inside the air motor that create sealing and drive rotation as compressed air flows through the motor. Over time they can chip, wear short, or become sticky—leading to slow spin-up, reduced torque and roug..

AirCraft Air Impact Wrench Service Kit – Bearings & Washer (4/5/7/10/27/35/42/43) For AT0006 (AT0006-SK01) At a Glance: Bearing and washer service kit for AirCraft AT0006 – replaces multiple support/spacer parts to restore smooth rotation and correct internal alignment. Inside an impact wrench, bearings and washers quietly do the hard work—supporting rotating assemblies, controlling end-float, and keeping everything aligned while the hammer mechanism does its violent little dance. When these p..

AirCraft Air Impact Wrench Service Kit – Air Flow Reg. (8/10-12) For AT0006 (AT0006-SK02) At a Glance: Air flow regulator service kit for AirCraft AT0006 – replaces parts 8 and 10-12 to bring back controlled power and stable airflow.
