AirCraft AT0016-37 Spring For Air Ratchet Wrench

At a Glance: Replacement coil spring for the AirCraft AT0016 air ratchet—provides the tension needed for crisp engagement and dependable control.

Tiny part, big responsibility. The AirCraft AT0016-37 Spring is a replacement coil spring used in the AirCraft Air Ratchet Wrench (AT0016 series) to apply consistent tension within the ratchet head or selector mechanism. Springs are what keep detents positive, pawls seated, and moving parts returning the way they should. When a spring fatigues, breaks, or loses its shape, the tool can feel loose, inconsistent, or start slipping because components aren’t being held firmly in place. Replacing the spring restores that “click-into-place” confidence and helps the ratchet operate smoothly and reliably.

AirCraft replacement spring for positive tension and consistent engagement

In ratchet assemblies, proper spring tension prevents partial engagement and reduces wear on teeth, pawls and selector parts. A fresh spring helps the mechanism seat correctly and stay there under load.

Extra Information

Intended as a spare part for AirCraft Air Ratchet Wrench mechanisms (AT0016 series).
Replace if the spring is cracked, stretched, corroded, or if the mechanism feels weak, loose or inconsistent.
Check related detent parts (balls, pins, pawls, plates) during service—wear often occurs together.
If a parts diagram is available under the Documents tab, use it to confirm exact position and orientation.

Pro Tip

Work over a clean tray and keep springs paired with their detents. A tiny dab of grease can hold small parts in place during assembly and improves the “positive click” feel.

Features

AT0016-series compatibility Designed as a replacement spring for the AirCraft Air Ratchet Wrench range.
Coil compression spring Provides consistent force through repeated cycles.
Workshop-ready durability Built to handle vibration, load changes and frequent actuation.
Ideal for repairs and rebuilds Recommended when servicing the ratchet head or selector components.

Benefits

Restores crisp engagement: Helps parts seat correctly for smoother, more dependable operation.
Improves reliability: Reduces drifting, weak return action, and inconsistent ratchet/selector behaviour.
Reduces wear risk: Proper tension helps prevent slipping and partial engagement that can damage mating parts.

Safety

Disconnect the air supply and bleed remaining pressure before servicing the tool.
Wear eye protection—springs and detent parts can release suddenly during disassembly.
Work over a clean surface to prevent small parts from getting lost.
Ensure all components seat correctly before closing the housing to avoid binding.
After reassembly, test at low pressure first to confirm smooth, safe operation.
