At a Glance: Replacement spacer ring for the AirCraft AT0016 air ratchet—keeps components correctly spaced for smoother engagement and less wear.
In a compact mechanism like an air ratchet, clearances are everything. A spacer might look simple, but it controls where parts sit, how they align, and how smoothly they move under load. The AirCraft AT0016-18 Spacer is a replacement spacer ring for the AirCraft Air Ratchet Wrench (AT0016 series). It helps set correct spacing and positioning between internal components—reducing end-float, improving engagement consistency and helping prevent premature wear. Perfect for rebuilds, repairs, and restoring that “tight and smooth” feel when a tool starts developing play or roughness.
AirCraft spacer ring for correct alignment and controlled movement
Spacer rings are used to maintain proper gaps and component location in gear trains and rotating assemblies. Replacing a worn or distorted spacer helps the mechanism run more predictably and protects higher-value parts from uneven stress.
Extra Information
Intended as a spare part for AirCraft Air Ratchet Wrench assemblies (AT0016 series).
Replace if the spacer is worn, distorted, cracked, or if you notice excessive play in the mechanism.
During rebuilds, inspect mating components (gears, sleeves, bearings and pins) for wear—spacers often show issues when other parts are also tired.
If a parts diagram is available under the Documents tab, use it to confirm placement and the correct stack order.
Pro Tip
Before reassembly, lay parts out in order and take a quick photo. Spacer stack order matters—and that one photo can save a lot of “why does this feel wrong?” later.
