Product Description
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 wears, you can get sloppy impacts, extra noise, uneven wear, and reduced torque delivery. The AirCraft AT0004-SK04 service kit replaces the hammer frame and bushing-related components (reference 10–13), helping your AT0004 impact wrench hit smoothly, consistently and with the authority it was built for.
Impact assemblies operate under heavy shock loads. Bushings and support frames wear over time, allowing play that robs power and accelerates damage. Renewing these parts helps maintain correct spacing and support for cleaner hammer action and longer service life.
