BILITOOLS 4" 2-Jaw Gear Puller – Compact Reversible Bearing & Pulley Extractor, CR-V Steel

The BILITOOLS 4" 2 Jaw Gear Puller is a compact, reversible bearing and pulley removal tool built from heat-treated CR-V steel for reliable, low-damage extraction in tight spaces.

This 4" 2-jaw gear puller from BILITOOLS is designed for precision removal of small bearings, pulleys, gears, and flywheels across automotive, motorcycle, bicycle, and light machinery work. Its reversible jaws allow internal or external pulling, and the heat-treated chromium-vanadium construction offers resistance to bending and wear. The size balances reach and torque, making it a go-to option when larger pullers are overkill and smaller extractors lack the grip or strength needed.

How does this puller handle tight or confined spaces?

The compact 4" frame and slim-profile jaws let you position the tool where larger pullers cannot fit, while the reversibility gives access to both internal and external pulls. The central forcing screw provides controlled force to avoid sudden slips or damage.

• Reversible jaw configuration for internal or external pulling
• 4" span suited to small shafts and housings
• Slim arm design for narrow clearance work
• Fine-thread forcing screw for smooth, controlled extraction

What materials and build quality can I expect?

BILITOOLS constructs this puller from heat-treated CR-V (chromium-vanadium) steel to improve tensile strength and reduce the chance of bending under load. The components are machined for accurate fit and consistent operation, making the tool dependable for repeated shop use.

• Heat-treated CR-V steel body and jaws for durability
• Precision-machined threads on the forcing screw
• Surface finish to resist corrosion and wear
• Sturdy crossbar and jaw pivots for consistent alignment

How easy is it to set up and use for DIYers and pros?

Setup is straightforward: position the jaws, reverse them if needed for internal pulls, center the forcing screw, and turn the screw to extract the part. The design emphasizes quick adjustment and a smooth pulling action that reduces manual effort and the need for makeshift fixtures.

• Quick jaw adjustment without special tools
• Clear centerline marking for accurate screw placement
• Ergonomic screw head for steady torque application
• Works equally well for single-job fixes or regular shop use

What parts and tasks is the 4" size best suited for?

The 4" model is optimized for small- to medium-sized components where precision matters more than brute force. It removes bearings, pulleys, small gears, and similar press-fit parts without requiring large, heavy pullers.

• Small bearings and bushings on shafts
• Pulleys on alternators, small motors, and scooters
• Flywheels and sprockets on light machinery
• Situations needing internal or external extraction with limited access

Who is this for: The BILITOOLS 4" 2 Jaw Gear Puller is aimed at home mechanics, motorcycle and bicycle technicians, and light-duty professional shops that need a reliable, compact extractor. Choose this size when you want a balance of accessibility and pulling power for small-to-mid components; BILITOOLS also offers a range of sizes if you need bigger reach or higher torque for heavier parts.
