Three-arm puller NEO tools 4" (TOP-11-861) — 3-jaw mechanical remover for bearings and gears

Three-arm puller NEO tools 4" (TOP-11-861) is a three-jaw mechanical remover sized for a 4-inch reach, designed to extract bearings, gears, pulleys and similar press-fit parts. The tool uses a central forcing screw and three evenly spaced arms to provide concentric, balanced pulling force, reducing the risk of part damage during removal. It is intended for use in automotive repair, industrial maintenance and general workshop applications where controlled extraction is required.

Advantages

The three-arm configuration ensures even distribution of force for concentric removal and improved stability compared with single- or two-arm pullers. The central forcing screw provides controlled, incremental force for safe extraction of press-fit components. The 4" reach makes the tool suitable for medium-depth applications while remaining compact enough for bench and mobile use. Construction materials and threaded components are designed for repeated mechanical use under workshop conditions.

Suitable for

• Removing bearings from shafts and housings
• Extracting gears and sprockets from axles
• Pulling pulleys, collars and press-fit components
• Automotive suspension and drivetrain maintenance
• Industrial equipment servicing and machine maintenance

Key specifications

• Tool type: three-jaw mechanical puller
• Reach: 4 inches (approx. 100 mm)
• Operation: central forcing screw for axial extraction
• Grip: three adjustable arms for internal or external engagement depending on configuration
• Typical applications: bearings, gears, pulleys, collars and similar press-fit parts

How to use

Select the appropriate arm orientation (internal or external) and fit the jaws securely around or behind the component to be removed. Position the puller so the central forcing screw bears on the drive surface or shaft end. Turn the forcing screw clockwise with a suitable wrench or socket to apply steady, controlled axial force until the component slides free. Reverse the screw to release the puller after removal. Inspect the component and mating surfaces for damage and clean contact areas before reassembly.

Usage recommendations

Use steady, incremental force rather than sudden impacts; apply penetrating lubricant to stuck parts if needed and protect mating surfaces with suitable pads or adapters to prevent scoring. For tightly fitted or corroded components consider applying heat to the housing or using a hydraulic or larger-capacity puller. Always wear appropriate personal protective equipment and follow safe workshop practices.
