DURATECH 4-Inch 3-Jaw Gear Puller, CR-V Steel, 4-Ton Capacity, Fully Assembled

DURATECH's 4-inch 3-jaw gear puller is a fully assembled CR-V steel removal tool that safely extracts gears, pulleys, bearings and flywheels with a balanced three-jaw grip and a 4-ton capacity.

This compact, ready-to-use puller is built from drop-forged chrome-vanadium (CR-V) steel with heat-treated jaws and corrosion-resistant finishes so you can tackle stubborn press-fit parts without fuss. The reversible three-jaw layout offers both internal and external gripping options, while the black-phosphated drive screw and chrome-plated claws resist wear and rust. Designed to work with common hand tools — wrench, ratchet, or spanner — it suits garage mechanics, home DIYers and professional technicians needing a reliable small-capacity puller.

How does the DURATECH 3-jaw design make removal easier?

The three jaws distribute force evenly around the part for a stable, non-slip extraction that reduces slippage and part damage. Jaws are machined precisely to bite securely, and their reversible configuration lets you switch between inside and outside pulls quickly without extra parts.

• Balanced force from three jaws for controlled straight pulls
• Reversible jaws support internal or external gripping
• Precisely machined claws reduce risk of rounding or slippage

What materials and finishes protect the tool under workshop conditions?

The main components are forged from chrome-vanadium steel and heat-treated to improve strength and durability under load. Chrome plating on the jaws guards against rust and corrosion, while the drive screw’s black-phosphating increases surface hardness and wear resistance for longer service life.

• Drop-forged CR-V steel for high tensile strength
• Heat-treated jaws for improved durability under heavy strain
• Chrome-plated claws and black-phosphated screw for corrosion resistance

What size range and capacity does this puller support?

This model is specified as a 4-inch puller with a 4-ton rated capacity and a maximum usable range around 100 mm. It offers a jaw spread of 4 inches and a reach that extends up to roughly 4-29/32 inches, making it suitable for many small- to medium-sized shafts and components. Note: measurements are hand-measured; verify fit for critical applications before purchase.

• Rated capacity: 4 tons for controlled extraction
• Jaw spread: 4 in; jaw reach: up to 4-29/32 in
• Maximum usable range: approximately 100 mm (confirm before use)

How will this tool fit into my workflow and maintenance tasks?

Because it ships fully assembled, you can use it immediately with standard hand tools to remove bearings, gears, pulleys, sprockets and flywheels. The compact footprint and short/standard reach settings make it particularly useful in confined spaces where larger pullers won’t fit.

• Ready-to-use out of the package—no assembly required
• Works with wrench, ratchet or spanner for flexible setup
• Compact size ideal for tight engine bays and machine housings

Who is this for: The DURATECH 4-inch 3-jaw puller is aimed at light-to-medium-duty users who need a dependable, compact extractor. It’s a practical choice for automotive hobbyists, small engine mechanics, maintenance technicians and anyone needing a corrosion-resistant, fully assembled 3-jaw solution for routine removal of gears, bearings, pulleys and similar parts. If you require higher capacities or longer reach, consider larger models; for typical garage and workshop tasks, this DURATECH unit delivers a durable, easy-to-use option.
