MANNIFEN 2-Jaw Gear Puller — 12 Inch 2-Claw Extraction Tool, Forged Chrome-Vanadium

The MANNIFEN 2-jaw gear puller is a forged chrome-vanadium removal tool designed to extract pulleys, gears, bearings and flywheels cleanly, either internally or externally.

This two-claw, adjustable puller gives you a compact, durable option for separating press-fit parts without causing nicks or damage. Built from heat-treated chrome vanadium steel and finished with features that improve safety and grip, it adapts to a wide range of automotive and mechanical tasks. Read on for how it works, what it fits, and why it’s useful in a home garage or professional shop.

How does the MANNIFEN puller remove parts without damaging them?

The design directs steady, centered force through a threaded spindle so parts come off evenly instead of getting pried or bent. Reversible jaws let you set the claws for internal or external pulls, which keeps contact points secure and prevents slippage.

• Threaded spindle with hexagonal head for controlled, axial force
• Reversible two-jaw configuration for internal or external extraction
• Anti-slip flange and button on beam to stabilize the assembly during use
• Forged, heat-treated chrome vanadium construction resists spreading or deformation

What sizes and parts will this 12-inch puller work on?

The tool is nominally a 12-inch model but practical jaw opening is limited by safety pins to about 9.84 inches, which suits most common bearings, pulleys and gears. Adjustable clamping depth and jaw width let you fit a variety of diameters for cars, motorcycles, bicycles and small machinery.

• Practical maximum jaw opening approximately 9.84 inches
• Adjustable clamping depth for shallow or deep fits
• Reversible claws for both inside and outside gripping tasks
• Ideal for automotive flywheels, pulleys, bearings, and machine wheels

What safety and ergonomic features are included?

The spindle has a hex head with a surrounding flange to keep sockets and wrenches from slipping during heavy turns. A locking button on the beam increases stability and makes it quicker to switch between internal and external jaw setups, reducing fumbling and accidental slips.

• Hexagonal spindle head with flange prevents tool slip
• Beam button secures jaw position for safer operation
• Solid forged body withstands high torque without fracturing
• Compact footprint helps maintain control in tight engine bays

How do I set up and use the puller for a typical job?

Choose inside or outside jaw orientation, secure the claws around the component, center the spindle on the shaft, and then turn the hex head steadily to draw the part off. Use even, moderate torque and reposition the jaws if progress stalls to avoid uneven loading.

• Select jaw orientation (internal or external) and lock in with the beam button
• Center the spindle tip on the shaft or pilot hole before applying force
• Turn the spindle with a wrench/socket, applying steady pressure
• Re-adjust clamping depth if the component binds or tilts

Who is this for? The MANNIFEN 2-jaw gear puller fits DIY mechanics, mobile technicians, and small repair shops that need a dependable, compact puller for routine removal tasks. It’s particularly useful where controlled, damage-free extraction is required, and for users who prefer a reversible-jaw tool that covers both inside and outside pulls without buying multiple specialized pullers.
