AirCraft Internal Sleeve For AT0012 Reversible Air Drill (AT0012-31)

At a Glance: Replacement internal splined sleeve that supports drive alignment and stable engagement within the AT0012 drill assembly.

When an air drill starts feeling loose, “notchy”, or inconsistent under load, it’s often a sign that an internal drive component is wearing out. The AirCraft AT0012-31 Internal Sleeve is a replacement sleeve/bushing used inside the AirCraft AT0012 reversible air drill. With its internal spline profile, this sleeve helps locate and guide drive components so power transfers smoothly through the mechanism. Replacing a worn sleeve can reduce play, improve engagement, and help the drill run smoother and more predictably.

Alignment and engagement matter—this internal sleeve helps your AT0012 stay tight, smooth and reliable.

Internal sleeves and splines keep rotating parts centred and correctly meshed. If the sleeve wears, components can shift under load, increasing noise and accelerating wear across the drive train.

Features

AT0012-specific replacement Designed for the AirCraft AT0012 reversible air drill.
Internal splined profile Supports positive engagement and controlled movement of the drive components.
Precision-machined fit Helps maintain alignment and smooth operation within the drill assembly.
Durable metal construction Built for repeated load cycles and workshop use.

Benefits

Restores smoother power transfer: Helps reduce slipping, uneven engagement and rough running.
Reduces play and vibration: A fresh sleeve can tighten internal alignment and improve tool feel.
Protects related parts: Correct alignment reduces abnormal wear on shafts, gears and mating splines.
Smart refurbishment item: A practical spare part for keeping an AT0012 drill performing like it should.

Extra Information

Compatibility: For the AirCraft AT0012 reversible air drill. Confirm part number before ordering.
Service note: When replacing a splined sleeve, inspect the matching shaft/spline for wear or rounding for best results.
Lubrication: Use correct lubrication/grease (as applicable to the assembly) during reassembly to reduce wear and improve longevity.

Pro Tip

If you’re repairing internal drive wear, replace worn parts as a set where possible—new sleeves paired with heavily worn splines can still feel loose and wear faster.

Safety

Wear eye protection when servicing pneumatic tools and handling small metal components.
Disconnect the air supply and release pressure before opening the drill or removing internal parts.
Keep components clean and organised during disassembly—metal debris or incorrect assembly can cause tool failure.
After reassembly, test-run the drill briefly in a clear area to confirm smooth operation before returning to full use.
