Ingersoll Rand 236 Air Impact Wrench | 1/2" Drive | 7400 RPM | 450 ft-lbs Max Torque | Trigger Start

For automotive repair, tire service, and general mechanical maintenance, the Ingersoll Rand 236 Pistol Grip Air Impact Wrench delivers practical fastening power in a conventional full-size pneumatic tool. Equipped with a 1/2" square drive with hog-ring socket retention, this impact wrench provides 450 ft-lbs (610 Nm) of maximum reverse torque for loosening stubborn nuts and bolts. Its 25–200 ft-lbs (34–271 Nm) working torque range makes it suitable for a variety of vehicle service and mechanical fastening tasks, while the 7,400 RPM free speed (rotational speed without load) supports efficient fastener rundown. The jumbo hammer impact mechanism delivers rotational impacts to the drive, helping remove tight fasteners without requiring the operator to apply continuous manual turning force.

The Ingersoll Rand 236 combines a finely tuned vane motor (a compressed-air motor using sliding vanes to generate rotation) with a jumbo hammer impact mechanism for consistent power delivery. Its forward/reverse power regulator provides control over fastening direction and output during service operations. The wrench features a 7.1" (180 mm) overall length according to the Vehicle Services Catalog and weighs 5.3 lbs (2.4 kg), making it a practical option for regular workshop use. Operating at 90 PSI (6.2 bar), the tool requires a 1/4" air inlet and 3/8" minimum air hose. With 24 CFM air consumption at load and 4.3 CFM average air consumption, the 236 provides clearly defined requirements for matching the wrench to an appropriately sized compressed-air system.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator (FRLs)

Applications:

• Automotive repair and service – Removing suitable wheel fasteners, mounting bolts, and mechanical hardware during routine vehicle maintenance.
• Tire shops and service bays – Supporting wheel removal and installation operations using compatible 1/2" drive impact sockets.
• Fleet and light truck maintenance – Servicing accessible threaded fasteners on fleet vehicles and workshop equipment within the wrench's rated capability.
• Industrial maintenance and MRO – Loosening bolts on machinery brackets, equipment housings, and mechanical assemblies during servicing or component replacement.
• General repair workshops and home garages – Performing mechanical repairs, equipment refurbishment, and routine nut and bolt removal with an adequate compressed-air supply.

FAQs:

• Q: How much torque does the Ingersoll Rand 236 impact wrench produce?
  A: Ingersoll Rand specifies 450 ft-lbs (610 Nm) of maximum reverse torque. Its Vehicle Services Catalog also lists a 25–200 ft-lbs working torque range. Maximum reverse torque describes the tool's rated loosening capability, not a calibrated tightening setting.
• Q: What is the difference between the Ingersoll Rand 236 and 231C?
  A: The 236 produces 450 ft-lbs maximum reverse torque at 7,400 RPM and weighs 5.3 lbs. The 231C provides 600 ft-lbs maximum reverse torque at 8,000 RPM and weighs 5.8 lbs. The 236 uses a jumbo hammer impact mechanism, while the 231C offers a higher reverse torque rating for applications requiring additional loosening power.
• Q: What air compressor capacity does the Ingersoll Rand 236 require?
  A: The manufacturer specifies 24 CFM air consumption at load and 4.3 CFM average air consumption, with a recommended operating pressure of 90 PSI. The wrench requires a minimum 3/8" air hose and has a 1/4" air inlet. Select compressor capacity according to the expected duty cycle and ensure adequate airflow reaches the tool during operation.
• Q: Does the Ingersoll Rand 236 use hog-ring socket retention?
  A: Yes. The 236 has a 1/2" square drive with hog-ring retention. A hog ring is a retaining ring on the anvil that helps keep compatible impact sockets in place while allowing them to be changed when needed. Always use properly fitted impact-rated sockets.
• Q: Can the Ingersoll Rand 236 be used to change vehicle tires?
  A: Yes. The manufacturer identifies vehicle repair as a primary application for this impact wrench. It can remove and install compatible wheel fasteners, but final wheel-nut tightening should be completed with a calibrated torque wrench according to the vehicle manufacturer's specified torque.
