Asnfanl 3-Piece Reversible 3-Jaw Puller Set 3"/4"/6" — Heat-Treated Steel, Anti-Rust Finish

The Asnfanl 3-piece reversible 3-jaw puller set is a heavy-duty gear and bearing extractor kit with 3", 4" and 6" reach, designed to remove gears, pulleys and bearings safely and evenly.

This puller set groups three different-sized reversible three-jaw tools in one kit so you can tackle a wide range of disassembly tasks without improvising. Each puller features drop-forged, heat-treated steel construction with an anti-rust finish and a central forcing screw that accepts sockets or spanners. The jaws flip to operate as internal or external pullers, and the three-jaw layout distributes force for steadier, more balanced removal of stuck components.

How do the three jaw sizes help with different repair jobs?

The kit includes 3", 4" and 6" pullers, giving you compact, medium and extended reach options. That range covers common automotive, industrial and home maintenance work where parts vary in diameter and depth.

• 3" puller: best for small pulleys, bearings and tight spaces.
• 4" puller: mid-size components like alternator pulleys or medium bearings.
• 6" puller: larger gears, flywheels or assemblies with deeper seating.

What makes the jaws reversible and why is that useful?

Each jaw flips to convert between internal and external pulling modes, so the same tool can grip either the inside lip or the outside edge of a part. That flexibility reduces the need for multiple specialized tools and speeds up setups.

• External pull: jaws hook around the component edge for outward removal.
• Internal pull: jaws expand behind a bore to push the component outwards.
• Reversible design: single jaw set serves both functions, saving space and cost.

How durable and safe is the Asnfanl puller set under heavy use?

Manufactured from drop-forged, heat-treated steel with an anti-corrosion coating, these pullers are built to withstand repeated torque and resist environmental wear. The three-jaw geometry keeps force centered, reducing slippage and the risk of damaging parts when used correctly.

• Heat-treated steel: improved strength and fatigue resistance.
• Anti-rust coating: better longevity in workshop conditions.
• Even force distribution: lowers chances of part deformation during extraction.

How do I use the central forcing screw with my sockets or spanners?

The central screw is threaded to draw the jaws inward as it is turned; its head accepts standard sockets or wrench heads so you can apply torque with familiar tools. Use steady, even turns and, if needed, a penetrating lubricant to ease stubborn parts.

• Fits sockets and spanners: works with common drive tools for convenience.
• Turn evenly: maintain alignment to prevent skewing the jaws.
• Use lubricant if seized: reduces stress on the puller and part.

Who is this for: The Asnfanl 3-piece reversible 3-jaw puller set is aimed at mechanics, maintenance technicians, industrial service crews and serious DIYers who need a compact selection of versatile extractors. If you frequently remove gears, pulleys, bearings or similar press-fit parts — and want a durable, space-saving kit that works with common hand tools — this set provides multiple sizes and reversible jaws for flexible, steady extraction in garage, shop or field settings.
