Cylinder For Air Ratchet Wrench

Features

• AT0016-series compatibility Designed as a replacement cylinder for the AirCraft Air Ratchet Wrench range.
• Precision internal bore Provides the correct running surface for rotor blades/vanes.
• Porting and locating features Designed to align correctly within the motor assembly.
• Durable metal construction Built to handle high-speed vane contact and workshop conditions.

Benefits

• Restores torque and efficiency: Better internal sealing helps deliver stronger, more consistent power.
• Smoother running: A clean bore reduces friction and improves motor response.
• Protects new vanes: Replacing a scored cylinder prevents rapid wear on fresh rotor blades.
• Extends tool life: A healthy cylinder reduces heat build-up and strain on motor components.

Extra Information

• Intended as a spare part for AirCraft Air Ratchet Wrench motor assemblies (AT0016 series).
• Replace the cylinder if the internal bore is scored, pitted, or if performance remains weak after replacing vanes and lubricating properly.
• During rebuilds, inspect the rotor, end plates and bearings—worn parts often work together to create rough running.
• If service documentation is available under the Documents tab, use it to confirm orientation and assembly order.

Specifications

Safety

• Disconnect the air supply and bleed remaining pressure before opening the motor assembly.
• Wear eye protection—springs, pins and small parts can release during disassembly.
• Handle precision parts carefully—dropping or nicking the cylinder can affect sealing and performance.
• Keep the work area clean; grit can score the cylinder and ruin new vanes quickly.
• After reassembly, test the tool at low pressure first to confirm smooth running before returning to normal operating pressure.
