AirCraft AT0016-40 Block Ring For Air Ratchet Wrench
At a Glance: Replacement block ring (retaining circlip) for the AirCraft AT0016 air ratchet—keeps key components securely located under vibration and load.
If you’ve ever opened a tool and found a “mystery ring” missing… that ring usually wasn’t optional. The AirCraft AT0016-40 Block Ring is a replacement retaining ring (circlip/snap ring style) used in the AirCraft Air Ratchet Wrench (AT0016 series) to hold components in their correct position within the assembly. It prevents axial movement, keeps stacks seated, and helps the mechanism maintain correct clearances while the tool is working under vibration and torque loads. A worn, bent, or fatigued retaining ring can lead to excess play, rough operation, or internal parts shifting out of place. Replacing the block ring restores secure retention and helps keep the ratchet running smoothly and reliably.
Retaining rings are used to “lock” bearings, sleeves, plates or gear stacks into position. Correct retention prevents shifting, reduces noise, and protects neighbouring components from abnormal wear.

Extra Info
Extra Information
- Intended as a spare part for AirCraft Air Ratchet Wrench assemblies (AT0016 series).
- Replace retaining rings if they are stretched, bent, cracked, or no longer snap firmly into the groove.
- Always inspect the retaining groove for damage—burrs can prevent correct seating.
- If a parts diagram is available under the Documents tab, use it to confirm the correct ring position in the assembly.
Pro Tip
- Use proper circlip pliers for installation/removal and ensure the ring seats fully into the groove all the way around. A half-seated ring is a future “why is this rattling?” moment.
Safety
Safety
- Disconnect the air supply and bleed remaining pressure before servicing the tool.
- Wear eye protection—circlips can spring loose during removal or installation.
- Use the correct circlip pliers to avoid slipping and damaging the ring or surrounding parts.
- Confirm the ring is fully seated in its groove before reassembly.
- After reassembly, test at low pressure first to confirm smooth, safe operation.
