Pulley puller AWTools AW18991, compact hand tool, weight 560 g

AWTools AW18991 is a compact hand-operated pulley puller designed for controlled extraction of pulleys, gears, bearings and other press-fit rotating parts. Made of drop-forged tool steel with hardening and tempering, this compact puller combines durability with a lightweight design (560 g) suitable for workshop use and automotive maintenance. The sliding, reversible arms and central hex-head screw enable inside and outside grips and precise force application when paired with a ratchet wrench.

Advantages

The construction from hardened and tempered tool steel ensures strength and resistance to deformation during repeated use. A black oxide finish on the central screw improves corrosion resistance and allows smooth operation with a standard ratchet wrench. Satin-plated arms reduce slippage on contact surfaces while the sliding-arm design lets you quickly adjust arm spacing for different diameters. Reversible arms provide both internal and external pull options, making the puller versatile for a range of components.

Suitable for

• Removing pulleys from shafts in automotive repairs
• Extracting bearings from housings or shafts
• Pulling gears, discs and rings during disassembly
• General workshop maintenance and light-duty mechanical service

Key specifications

• Construction: drop-forged tool steel, hardened and tempered
• Total weight: 560 g
• Central screw: hex head compatible with ratchet wrench, black oxide finish
• Arms: satin-plated, sliding adjustment, reversible for inside and outside grip
• Grip types: internal and external pull

How to use

Select the appropriate arm orientation for internal or external gripping and slide the arms to fit the component diameter. Position the arms securely behind the pulley, gear or bearing so the contact surface is stable. Fit a ratchet wrench to the central hex-head screw and turn gradually to apply even pulling force. Maintain alignment between the tool and shaft to avoid side loads; stop if the component binds and reassess arm seating. After removal, clean and inspect the tool before storage.

Usage recommendations

Use the puller with hand tools rated for the applied torque and avoid excessive impact or heat. Wear appropriate eye and hand protection. For seized or heavily corroded parts consider additional penetrating lubricant and apply force incrementally. Do not use the tool beyond light- to medium-duty automotive and workshop applications for which it is designed.
