Ingersoll Rand 3/8 Inch Air Ratchet Wrench, 54 Ft-Lbs Max Torque, 160 RPM

Description

Mechanics battle cramped engine clearance with the Ingersoll Rand 3/8-Inch Air Ratchet to run down water pump bolts, alternator brackets, and under-dash fasteners without knuckle scrapes. The heat-treated alloy steel ratchet head produces up to 54 ft-lbs of maximum torque at 160 RPM free speed on 90 PSI shop air. Automotive technicians spin threaded fasteners rapidly in restricted spaces. The reaction-torque mechanism transfers rotational kickback into the operator’s hand when fasteners seat flush.

Solid cast aluminum forms the handle body, wrapped in an ergonomic textured grip that insulates the technician’s palm from chilled motor exhaust air. The heat-treated ratchet head encases twin pawl drive teeth and hardened alloy steel planetary gears that resist gear tooth stripping under heavy hand break-away pulls. Sized for automotive engine bays, the bare air ratchet weighs 2.8 lbs, measuring 10.5 inches long with a 3/8-inch square drive ball-socket retainer.

Torque Output Dynamic Bench Limits

Dynamometer bench testing confirms the pneumatic ratchet delivers 54 ft-lbs of maximum torque under full stall conditions, maintaining 160 RPM free speed at 90 PSI dynamic line pressure. Threading a 5/16-inch Grade-8 bolt into tapped cast iron completes in 2.5 seconds without gear slippage. The needle-bearing supported drive head withstands 125 ft-lbs of manual break-away torque when used as a hand ratchet. Air consumption measures 3.5 CFM at idle and 16 CFM under continuous rundown load.

Key Features of Ingersoll Rand 107XPA

Automotive repair technicians and small engine mechanics buy Ingersoll Rand 3/8-Inch Air Ratchets to run engine bay fasteners and transmission fluid pan bolts. Compare commercial pneumatic ratchet wrench pricing to upgrade your automotive service bay tooling.

• Delivers 54 ft-lbs of maximum reaction torque at 160 RPM, spinning long automotive bolts out of deep cavities cleanly.
• Heat-treated ratchet head houses twin-pawl drive teeth to spread mechanical load and prevent tooth stripping cleanly.
• Variable-speed paddle throttle allows feathering speed from zero to full 160 RPM for precise fastener starting cleanly.
• Adjustable 360-degree rear exhaust deflector routes compressed air discharge away from technician work faces cleanly.
• Compact 10.5-inch overall length reaches into narrow engine compartments where standard impact wrenches cannot fit cleanly.
• Ball-detent socket retainer holds commercial chrome sockets firmly in place during high-vibration fastener rundowns squarely.

Automotive Bay Negative Selection Filter

The variable throttle paddle permits feathering rotational speed, starting bolts into aluminum cylinder head threads without cross-threading. Do not purchase this pneumatic air ratchet for heavy vehicle wheel lug nuts requiring over 100 ft-lbs, continuous structural steel framing, or operating on small 1-gallon finish compressors lacking 4 CFM delivery. Routine care requires adding three drops of air tool oil into the air fitting daily before connection, and greasing the ratchet head through the flush fitting monthly.
