Ingersoll Rand 261-3 Air Impact Wrench | 3/4" Drive Size | 5500 RPM | 1,100 (ft-lbs) Max Torque

For commercial vehicle maintenance and heavy machinery repairs involving recessed fasteners, the Ingersoll Rand 261-3 Pistol Grip Pneumatic Impact Wrench combines substantial fastening power with an extended-reach configuration. Equipped with a 3/4-inch square drive and 3-inch extended anvil, this impact wrench helps technicians reach wheel nuts, suspension fasteners, and mechanical connections positioned beyond the reach of standard-anvil tools. The current manufacturer specifications list 1,100 ft-lbs (1,491 Nm) of forward torque and 1,200 ft-lbs (1,627 Nm) of maximum reverse torque for loosening resistant bolts. Its 5,500 RPM free speed supports rapid fastener rundown, while the 1,000 blows per minute (BPM) impact rate provides repeated rotational impacts for substantial fastening and removal operations.

The Ingersoll Rand 261-3 features a jumbo hammer impact mechanism, which uses a large impact hammer to transfer rotational force to the output drive while providing a serviceable mechanical design. Its vane motor produces the pneumatic power needed for heavy vehicle and machinery maintenance, while the adjustable power regulator allows operators to control output according to the fastening task. A square-drive hog-ring retainer (a friction ring that helps hold an impact socket on the anvil) supports secure socket engagement during operation. Measuring 11.8 inches (300 mm) in overall length and weighing 13 lbs (5.9 kg), the 261-3 provides additional reach compared with the standard-anvil 261 model. With a 3/8-inch air inlet, 1/2-inch minimum hose size, and 38 CFM air consumption at load, this pneumatic impact wrench is suited to properly equipped fleet maintenance shops, heavy vehicle service facilities, and industrial repair operations.

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

Applications:

• Commercial truck and fleet maintenance: Removing recessed wheel fasteners and servicing suitable suspension, chassis, and mechanical assemblies.
• Heavy equipment repair: Loosening large bolts on construction equipment, agricultural machinery, and other mechanical assemblies requiring additional anvil reach.
• Automotive and vehicle service: Accessing suitable suspension and drivetrain fasteners where surrounding components limit the use of standard-anvil impact wrenches.
• Industrial maintenance and MRO: Performing machinery disassembly, equipment repairs, and high-resistance fastener removal in compressed-air-equipped workshops.
• Commercial repair facilities: Servicing large mechanical fasteners during routine fleet maintenance and equipment refurbishment.

FAQs:

• Q: What is the difference between the Ingersoll Rand 261 and 261-3 impact wrenches?
  A: The primary difference is the anvil length. The standard 261 measures 8.8 inches overall, while the 261-3 incorporates a 3-inch extended anvil and measures 11.8 inches overall. Both use a 3/4-inch square drive and share the same published forward and reverse torque specifications. The 261-3 provides additional reach for recessed fasteners.
• Q: Does the Ingersoll Rand 261-3 produce 1,100 or 1,200 ft-lbs of torque?
  A: The current Ingersoll Rand manufacturer specification table lists 1,100 ft-lbs (1,491 Nm) of forward torque and 1,200 ft-lbs (1,627 Nm) of maximum reverse torque. An older vehicle-service catalog lists 1,100 ft-lbs as maximum torque. These figures come from different manufacturer publications, so buyers should distinguish the torque direction and specification revision when comparing ratings.
• Q: What compressed-air supply does the 261-3 require?
  A: Ingersoll Rand specifies 38 CFM air consumption at load, 9.5 CFM average air consumption, and 90 PSI operating pressure. The tool requires a minimum 1/2-inch air hose and uses a 3/8-inch air inlet. Compressor sizing should account for airflow under load, the intended duty cycle, and other equipment connected to the compressed-air system.
• Q: What type of sockets can be used with the 261-3?
  A: The 261-3 accepts appropriately rated 3/4-inch square-drive impact sockets. Its hog-ring retention system helps hold the socket on the anvil during operation. Always verify socket fit, retention compatibility, and accessibility before use.
• Q: Is the 3-inch extended anvil useful for truck wheel service?
  A: Yes. The additional anvil length helps operators reach wheel fasteners that are recessed within certain wheel assemblies. However, wheel configurations vary, so verify the required reach and socket dimensions. Always use a calibrated torque wrench to confirm final wheel-fastener tightening.
