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

DURATECH 4-Inch 3-Jaw Gear Puller is a fully assembled, heat-treated CR-V steel removal tool designed to extract gears, bearings, pulleys and flywheels with a balanced 3-jaw grip and a 4-ton capacity.

Built for home mechanics and professional technicians, this 4-inch DURATECH 3-jaw gear puller arrives ready to use and is engineered for durability and corrosion resistance. The jaws are drop-forged from chrome-vanadium (CR-V) steel and heat-treated for added strength, while fine chrome plating and black phosphating protect the gripping surfaces and drive screw. It reverses for inside or outside pulling, fits tight spaces, and provides a secure, non-slip hold for smooth part removal.

How does the DURATECH gear puller grip parts securely?

The three jaws distribute force evenly around a part to prevent slipping or damage during extraction. Each claw is precisely machined for a non-slip bite, and the reversible jaw design enables inside or outside grips depending on the job.

• 3 jaws for balanced pulling force and stable extraction
• Precisely machined claw edges to minimize slippage
• Reversible 4-position jaws for inside or outside pulling
• Short and standard reach options for confined areas

What materials and finishes increase the tool’s durability?

Key wearing parts are made of drop-forged CR‑V steel and heat-treated to resist deformation under load. Corrosion-resistant finishes—fine chrome plating on the jaws and black phosphating on the drive screw—extend service life and maintain reliable operation.

• Drop-forged CR‑V steel jaws: strength and toughness
• Heat treatment: improved hardness and wear resistance
• Fine chrome plating on jaws for rust protection
• Black-phosphate drive screw for maximum longevity

What sizes and capacities does this model support?

This DURATECH puller is a 4-inch model with a jaw reach of approximately 4–29/32 inches and a usable maximum range near 100 mm. It’s rated for a 4-ton puller capacity and is suitable for removing gears, sprockets, bearings, pulleys and flywheels from shafts of compatible size.

• Jaw spread: 4 inches
• Jaw reach: 4–29/32 inches (approx.)
• Maximum usable range: ~100 mm
• Puller capacity: 4 tons

Do I need to assemble the puller before use?

No assembly is required—the DURATECH 3-jaw puller comes fully assembled so you can set it up quickly with a wrench, ratchet, or spanner. This saves time in the workshop and reduces the chance of incorrect assembly that could compromise safety.

• Delivered fully assembled for immediate use
• Works with common tools: wrench, ratchet, spanner
• Saves setup time and minimizes assembly errors
• Compact design for tight or hard-to-reach jobs

Who this is for: The DURATECH 4-Inch 3-Jaw Gear Puller suits automotive technicians, small-engine mechanics, motorcyclists, and DIY hobbyists who need a reliable, compact extractor. It’s especially useful when working in confined spaces or on jobs where even force distribution is important—such as removing pulleys, bearings, and flywheels—while offering corrosion-resistant finishes for regular shop use. Confirm your shaft and part dimensions before purchase to ensure compatibility with the stated jaw reach and spread.
