Puller 3‑arm 150 mm Jonnesway AE310036

The Jonnesway Puller 3-arm 150 mm AE310036 is a three-arm mechanical puller designed for removing gears, bearings, pulleys and other press-fit parts with a maximum reach of 150 mm. It features three adjustable arms that distribute extraction force evenly and a central forcing screw that enables controlled disassembly. The tool is intended for automotive and light industrial maintenance tasks where stable, centered pulling action is required.

Advantages

The three-arm configuration provides balanced gripping around the component to reduce slippage and damage. Adjustable arms allow adaptation to different diameters and shapes, while the central forcing screw permits gradual, controlled application of force. Constructed for workshop use, the puller offers a compact design that is simple to position and operate in confined spaces. Compatibility with common workshop tools and straightforward setup contribute to efficient removal of press-fitted parts.

Suitable for

• Removing gears from shafts
• Extracting bearings from housings
• Pulling pulleys and sprockets
• Light industrial maintenance and repair work
• Automotive repair tasks requiring centered extraction

Key specifications

• Arm configuration: three arms for balanced grip
• Maximum reach: 150 mm
• Adjustment: movable arms for varying component diameters
• Operation: central forcing screw for controlled force application
• Typical applications: gears, bearings, pulleys, sprockets and similar press-fit parts

How to use

Position the puller so that the three arms securely engage the back or edge of the component to be removed. Adjust the arms inward or outward until they sit evenly around the part, ensuring a centered grip. Turn the central forcing screw clockwise using an appropriate wrench or socket to apply gradual pull on the component while keeping the tool aligned with the shaft. Monitor the component and tool alignment during extraction to prevent slipping or damage. Reverse the screw to release the puller after removal.

Usage recommendations

Before use, inspect the arms and forcing screw for wear or damage and ensure all moving parts move freely. Use appropriate personal protective equipment and apply steady, controlled torque; avoid sudden or excessive force. For seized or heavily corroded parts, consider applying penetrating lubricant and alternate gentle heating and gradual pulling rather than increasing torque abruptly. Store the puller in a dry place and lubricate the screw periodically to maintain smooth operation.
