Reywoo 2-Jaw Gear Puller 4" Compact CR-V Steel, Reversible Jaws & Hex-Head Spindle for Tight Spaces

The Reywoo 4" 2-Jaw Gear Puller is a heat-treated chrome vanadium tool engineered to remove bearings, pulleys, flywheels and gears both externally and internally with adjustable depth and reversible jaws.

Whether you’re working on a car, motorcycle, small engine or industrial machinery, this compact but sturdy gear puller delivers controlled extraction in tight spaces. Its two-jaw reversible arms, hex-head spindle and locking beam button let you switch quickly between inward and outward pulls while maintaining alignment and grip. Built from hardened CR-V steel, it handles frequent use and heavy-duty removal tasks without bending or stripping.

How does the puller switch between internal and external removal?

Switching modes is fast: reverse the jaws and engage the beam’s locking button to set the arm position. The reversible-arm design lets you use the same tool for both internal and external applications, reducing the need for multiple pullers in your toolbox.

• Reversible jaws flip between inward-facing and outward-facing positions.
• Locking button secures the beam when selecting mode, preventing slippage.
• Hex-head spindle provides consistent axial force for controlled pulling.
• Adjustable beam depth adapts to different part thicknesses.

What size parts can this 2-jaw puller handle?

The Reywoo 4" puller covers a wide practical range: it supports external spreads up to 4.4 inches and internal spreads up to 4.79 inches, with a zero to 4.4" external range and 1.77" to 4.79" internal reach. That makes it suitable for many small-to-mid sized bearings, gears and pulleys encountered in automotive and equipment repair.

• External spread: 0–4.4 inches for hub and pulley removal.
• Internal spread: 1.77–4.79 inches for bearing and race extraction.
• Adjustable depth works in recessed or shallow bores.
• Compact 4" frame reaches into tighter assemblies than larger pullers.

How does construction and design improve safety and performance?

Heat-treated chrome vanadium construction resists deformation and gives the puller long service life under heavy loads. The hex-head spindle reduces slippage when applying torque and the beam locking feature keeps jaws aligned, which lowers the risk of sudden releases or damage to parts.

• Heat-treated CR-V steel for strength and wear resistance.
• Hex-head spindle prevents driver slippage during tightening.
• Beam locking button maintains jaw orientation and stability.
• Precision-machined jaw tips grip securely to avoid marring surfaces.

What practical accessories or scenarios is it suited for?

This tool is ideal for routine shop jobs and field repairs where portability and versatility matter. It works well on brake drums, steering components, alternator pulleys, small flywheels and many bearing assemblies where controlled extraction prevents part damage and reduces rework.

• Automotive alternator, pulley and bearing removal.
• Motorcycle and ATV wheel hub and small flywheel extraction.
• Industrial machine maintenance where space is limited.
• Home garage projects requiring safe, damage-free pulls.

Who is this for? The Reywoo 4" 2-jaw gear puller suits DIY mechanics, professional technicians and maintenance crews who need a compact, reliable extractor that swaps quickly between internal and external pulls. If you value a durable, easy-to-handle tool for frequent bearing, pulley or gear removal in constrained spaces, this puller offers a cost-effective, long-lasting solution.
