AirCraft Air Impact Wrench Service Kit – Hammer Gasket & Washers (4 / 6 / 8 / 9 / 14 / 23) for AT0004 (AT0004-SK01)
At a Glance: Sealing and spacing service kit for the AirCraft AT0004 impact mechanism, including gaskets, Washers and small retaining components for a tight, correct rebuild.
Inside every impact wrench, the hammer mechanism needs correct spacing and reliable sealing to deliver consistent power. If gaskets flatten, Washers wear, or small retaining parts are missing, the tool can start leaking, running rough, or losing impact efficiency. The AirCraft AT0004-SK01 service kit supplies the hammer gaskets and Washers (reference 4, 6, 8, 9, 14 and 23) needed to refresh the sealing surfaces and restore correct fitment in the AT0004 impact wrench. It’s an ideal kit for preventative maintenance or for rebuilding after a hammer service.
Gaskets and Washers might look “minorâ€, but they control sealing, alignment and end-play in the impact section. Replacing tired seals and worn Washers helps keep the mechanism tight, reduces unwanted movement, and supports smooth, reliable striking action.
