AirCraft Air Impact Wrench Service Kit – Hammer Case Complete (1–3 / 5 / 7) for AT0004 (AT0004-SK02)

At a Glance: Complete hammer case service kit for the AirCraft AT0004 including hammer case/housing, large sealing ring, screws and retaining clips for a solid rebuild.

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. If the case is cracked, worn, or leaking, you’ll often notice grease loss, contamination, noisy operation or reduced impact performance. The AirCraft AT0004-SK02 hammer case complete kit replaces the hammer case components (reference 1–3, 5 and 7) including the sealing ring and hardware, giving your AT0004 impact wrench a fresh, properly sealed impact housing ready for hard work.

Rebuild the impact housing for a tight, protected hammer mechanism

A sound hammer case keeps the impact unit clean, lubricated and correctly supported. Replacing the housing and seal helps prevent dirt ingress and grease leakage, while restoring the structural integrity needed for consistent, efficient striking action.

Features

Direct-fit for AirCraft AT0004 Matched to the AT0004 parts breakdown (reference 1–3 / 5 / 7).
Hammer case/housing component Replaces the impact mechanism outer case for proper containment and protection.
Large sealing ring included Helps maintain a tight seal to keep grease in and contaminants out.
Fasteners and clips supplied Includes screws and retaining clips for a complete installation (as shown).

Benefits

Helps stop leaks: New sealing components can reduce grease loss and improve tool cleanliness.
Protects the impact mechanism: A fresh case reduces the chance of dirt ingress and internal wear.
Restores reliable operation: Correct fitment and alignment support smoother, more consistent impacts.

Extra Information

Fits: AirCraft AT0004 Air Impact Wrench.
Parts reference: 1–3 / 5 / 7 (hammer case complete components as per AT0004 breakdown).
When rebuilding the hammer case, clean out old grease and inspect the hammer/anvil surfaces—fresh housing works best with a properly serviced impact unit.

Pro Tip

Apply the correct impact wrench grease inside the hammer case and lightly oil the seal before assembly—this helps the seal seat smoothly and prevents pinching during installation.
