DURATECH 3-Jaw Gear Puller 4-Inch — CR-V Steel, Fully Assembled, Reversible Grip

DURATECH's 4-inch 3-jaw gear puller is a fully assembled, heavy-duty CR-V steel tool designed to remove gears, bearings, pulleys and flywheels up to 4 tons of pull with a reversible inside/outside grip.

This compact, ready-to-use puller combines heat-treated chrome-vanadium (CR-V) steel construction with corrosion-resistant finishes for a reliable workshop tool. Its three jaws provide balanced force and non-slip contact, while the black-phosphated drive screw and chrome-plated jaws resist rust in everyday garage and industrial environments. Sized for smaller shafts and confined areas, the unit is built for mechanics, hobbyists and maintenance techs who need a durable, portable pulling solution.

How does this puller grip parts securely without slipping?

The DURATECH three-jaw layout distributes force evenly around the part, reducing the chance of tilting or slipping during removal. Each jaw is drop-forged and precision-machined for tight tolerances and a secure bite into gear teeth or bearing races.

• Three jaws balance the load to prevent cocking and part damage.
• Precisely machined claw edges give improved non-slip contact.
• Reversible jaws permit inside or outside engagement for different jobs.
• Short and standard reach options help access confined mounting positions.

What materials and finishes protect the tool from wear and corrosion?

The body and jaws are forged from chrome-vanadium steel and heat-treated for strength and toughness under repeated use. Chrome plating on the jaws and black phosphating on the drive screw increase resistance to rust and extend the tool's working life in workshop conditions.

• Drop-forged CR-V steel construction for high tensile strength.
• Heat treatment improves durability under heavy loads.
• Chrome-plated jaws shield gripping surfaces from corrosion.
• Black-phosphated drive screw adds longevity and smoother operation.

Can it fit tight spaces and different part sizes?

This model is compact by design: a 4-inch jaw spread with a reach up to 4-29/32 inches (maximum use range about 100 mm). The reversible 4-position jaws switch between inside and outside pulls and include short and standard reach orientations, making it practical for tight assemblies and smaller shafts.

• Jaw spread: 4 inches for narrow clearances.
• Jaw reach: up to 4-29/32 inches to accommodate different part depths.
• Maximum recommended working range: approximately 100 mm.
• Four-position jaw setup for inside or outside application flexibility.

How will this tool fit into my workflow and what tools are needed?

The DURATECH puller ships fully assembled, so you can use it immediately with common shop drive tools. It accepts a wrench, ratchet, or spanner on the drive screw, giving you flexible torque control for delicate or heavy removal tasks.

• Arrives fully assembled for immediate use—no setup required.
• Drive screw works with wrench, ratchet or spanner for variable torque.
• 3-jaw geometry is ideal for balanced, controlled extractions.
• Compact profile fits into engine bays, housings and confined gear locations.

Who is this for: The DURATECH 4-inch 3-jaw gear puller is made for professional mechanics, home-garage enthusiasts, small-facility maintenance crews and anyone who regularly removes gears, bearings, pulleys or flywheels in limited spaces. If you need a robust, corrosion-resistant puller with reversible jaws and immediate usability right out of the box, this tool offers a compact, dependable option for routine and occasional pulling jobs. Please confirm measurements against your application—sizes are hand-measured and may vary slightly.
