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 scored, the motor loses efficiency, power drops and heat increases. The AirCraft AT0004-SK05 rotor and cylinder service kit replaces the key air motor components (reference 16, 17, 19–21 and 24), helping your AT0004 return to strong, smooth performance with better sealing and stable alignment.

Rebuild the motor core for real performance recovery

The cylinder provides the sealing surface for vanes, while the rotor carries the vanes and transmits torque through the drive. Replacing worn rotor/cylinder components can dramatically improve efficiency—especially when the tool has seen heavy daily use or has run with poor lubrication.

Features

Direct-fit for AirCraft AT0004 Matched to the AT0004 parts breakdown (reference 16 / 17 / 19–21 / 24).
Rotor and cylinder components Replaces the main rotating and sealing elements of the air motor core.
Precision-fit motor parts Designed to restore correct clearances and alignment for efficient operation.
Ideal for full rebuilds Perfect when servicing a tired motor, internal scoring, or low-output performance.

Benefits

Restores motor efficiency: Improved sealing and fitment helps recover power and responsiveness.
Smoother rotation: Fresh, true-running components can reduce vibration and rough running.
Helps prevent further wear: Correct clearances reduce heat build-up and protect adjacent parts.

Extra Information

Fits: AirCraft AT0004 Air Impact Wrench.
Parts reference: 16 / 17 / 19–21 / 24 (rotor and cylinder-related components as per AT0004 breakdown).
For best results, pair a motor-core rebuild with fresh rotor blades (vanes) and correct pneumatic tool oiling practices.

Pro Tip

Before final assembly, wipe all motor parts clean and apply a light coat of pneumatic tool oil. First start-up should be at low pressure to distribute oil and confirm smooth operation.

Safety

Wear eye, ear and dust protection when servicing pneumatic tools.
Disconnect the air supply and bleed all pressure before opening the motor section.
Keep parts clean—dirt or grit inside the motor can score the cylinder and reduce service life.
After reassembly, test at low pressure first, then gradually return to working pressure while checking for abnormal noise or vibration.
