QWORK Ribbed Drive Pulley Crankshaft Remover Puller — Low-Profile Arms, 6.3" Max Jaw Opening

QWORK's Universal Ribbed Drive Pulley Crankshaft Remover is a compact, adjustable puller built to remove seized ribbed crankshaft and accessory pulleys in tight engine bays without harming the component.

This puller is engineered to tackle stubborn ribbed pulleys and accessory units such as alternators and A/C pump pulleys where space is limited. With low-profile arms and an adjustable jaw range, it gives technicians and DIYers the control and clearance needed to extract pulleys safely. The tool’s hole pattern and robust construction let you adapt to a variety of mounting configurations while minimizing the risk of marring or bending surrounding parts.

How does the QWORK puller remove pulleys in cramped engine compartments?

The low-profile arm design reduces bulk around the pulley, allowing the tool to fit between tight clearances and adjacent components. Once the arms are positioned and bolted, the central forcing screw applies steady, centered pressure to withdraw the pulley without slippage.

• Low-profile arms designed for limited clearance situations
• Central forcing screw provides controlled, even extraction
• Multiple attachment holes for versatile mounting options

What pulley sizes and openings will this remover accommodate?

The QWORK puller adjusts from a minimum close of 1-1/4 inches (35 mm) up to a maximum jaw opening of 6.3 inches (165 mm), covering a broad range of pulley diameters used on modern engines. The available span makes it practical for many crankshaft and accessory pulley removal tasks without needing additional adapters for most vehicles.

• Maximum jaw opening: 6.3 inches (165 mm)
• Minimum close: 1-1/4 inches (35 mm)
• Works with common crankshaft, alternator, and A/C pump pulleys

Is the tool compatible with different pulley attachment points and bolt patterns?

Yes — the arms include multiple 3/8" diameter holes and a middle section with matching fastener holes so you can align the puller to various bolt patterns. This hole layout allows secure fastening to ribbed pulleys, reducing movement during extraction and improving safety.

• Two side arms each feature six 3/8" holes for flexible mounting
• Middle assembly contains four 3/8" holes to match center positions
• Adapts to different pulley profiles and service needs

What safety and durability features should I expect while using it?

The puller’s stout construction and controlled forcing screw keep force centered on the pulley, lowering the chance of slipping or damage to bearings and adjacent components. Because the arms sit low and lean, there’s less contact with nearby brackets, hoses, and sensors during operation.

• Centered pressure application reduces side-load risk
• Low-profile arms to avoid contact with surrounding parts
• Heavy-duty components built for repeated workshop use

Who is this for? Mechanics and home technicians who frequently service modern engines with confined accessory layouts will find this tool especially useful. It suits professional shops performing routine belt and pulley work, independent mechanics, and DIYers who need a safe, adjustable solution for removing ribbed crankshaft and accessory pulleys without resorting to improvised pulls or risking component damage.
