At a Glance: Replacement spacer/shim for the AirCraft AT0016 air ratchet—sets correct clearances to keep the mechanism aligned and running smoothly.
In tight mechanical assemblies, a “little spacer” is basically a precision decision about how the whole tool behaves. The AirCraft AT0016-32 Spacer is a replacement spacer shim used in the AirCraft Air Ratchet Wrench (AT0016 series) to control clearance and component positioning. By keeping parts correctly spaced, it helps reduce end-float (unwanted movement), supports smooth engagement, and prevents metal-to-metal rubbing where it shouldn’t happen. If a spacer is worn, distorted, or missing, the ratchet can feel rough, develop play, or start wearing higher-value components faster. Replacing the spacer brings the assembly back into alignment for dependable, consistent operation.
AirCraft spacer shim for correct clearance and smoother engagement
Spacers and shims are used to fine-tune internal positioning—especially around bearings, plates and gear carriers. Correct spacing helps reduce backlash and protects parts from uneven stress and premature wear.
Extra Information
Intended as a spare part for AirCraft Air Ratchet Wrench assemblies (AT0016 series).
Replace if the spacer is bent, cracked, worn thin, or if the mechanism shows excessive play or uneven wear patterns.
When servicing, inspect related parts (bearings, plates, sleeves and gear carrier) as wear can occur together.
If a parts diagram is available under the Documents tab, use it to confirm correct position, orientation and stack order.
Pro Tip
Keep spacers organised in order during teardown. A simple “left-to-right” parts layout (or a quick photo) prevents stack-up mistakes that can cause binding or excessive play.
Features
AT0016-series compatibility Designed as a replacement spacer for the AirCraft Air Ratchet Wrench range.
Shim-style spacer profile Controls clearance and supports accurate component positioning.
Precision-cut form Helps components seat correctly for smooth operation.
Durable construction Built to handle vibration and repeated cycling in workshop use.
Benefits
Reduces play and rattle: Correct spacing helps minimise end-float and unwanted movement.
Improves smoothness: Better alignment reduces binding and rough engagement.
Protects key components: Prevents metal-to-metal contact and uneven loading on bearings, plates and gears.
Safety
Disconnect the air supply and bleed remaining pressure before servicing the tool.
Wear eye protection—small parts can release during disassembly and reassembly.
Keep work area clean and organise parts to prevent incorrect spacer stack-up.
Do not force assemblies closed; if it binds, re-check spacer order and component seating.
After reassembly, test at low pressure first to confirm smooth engagement and safe operation.
