ZKTOOL Ribbed Drive Crankshaft Pulley Puller Kit 35–160mm — Low‑Profile Adjustable Claws

ZKTOOL's Universal Ribbed Drive Crankshaft Pulley Puller Removal Tool Kit is a heavy-duty, adjustable puller engineered to remove V-ribbed belt pulleys, harmonic balancers, and drive pulleys from 35mm to 160mm without damage.

This compact kit gives mechanics and DIYers a controlled, low-profile method to extract press-fit pulleys from crankshafts, alternators, AC compressors and water pumps. Built with adjustable claws and locking hardware, the tool centers on the shaft and applies steady force so parts come off cleanly in tight engine bays. The set works with hand tools (17mm wrench or 3/8" square drive) and is optimized for confined spaces where larger pullers won't fit.

How does this puller prevent damage to pulleys and shafts?

The kit uses opposing adjustable claws that grasp the pulley lip securely and draw it off evenly, reducing side loading on the shaft and taper. Locking bolts stabilize the claws under tension so they don't slip while extracting a seized part.

• Adjustable claws clamp both sides of V-ribbed pulleys for even pull.
• Locking bolts keep claws fixed under load to avoid slippage.
• Centered forcing screw applies straight axial pressure to protect tapers.
• Durable steel construction resists bending during high force pulls.

Will the kit fit my pulley — what are the size and vehicle compatibility limits?

This universal puller accommodates pulleys from roughly 35mm up to 160mm in diameter, covering most ribbed drive pulleys found on modern passenger cars, light trucks and many small commercial engines. It is intended for V-ribbed belt pulleys and commonly used on crankshafts, alternators, AC units, and water pumps.

• Pulley diameter range: 35mm–160mm.
• Works on V-ribbed belt pulleys and common harmonic balancers.
• Suitable for most passenger cars, light trucks, and small commercial engines.
• Use with a 17mm wrench or 3/8" square drive ratchet/socket.

How does the low-profile design help in tight engine bays?

The arms and central forcing screw are fashioned to keep overall height and width minimized, enabling access between engine components where bulkier pullers cannot be positioned. That low profile reduces the need to remove surrounding parts before removal.

• Thin, low-clearance arms slide into narrow gaps easily.
• Compact forcing screw reaches the shaft in cramped locations.
• Fast, targeted removal minimizes disassembly of adjacent components.
• Locking features maintain grip even when space limits leverage.

What tools are required to operate the puller and how durable is it?

Operation requires a 17mm wrench or a 3/8" square drive ratchet/handle to turn the forcing screw. The kit is manufactured from heavy-duty steel and treated for corrosion resistance, designed to withstand repeated high-torque extractions in a repair shop environment.

• Use a 17mm wrench or 3/8" drive ratchet on the forcing screw.
• Locking bolts secure claws under tension for safe operation.
• Robust steel build resists deformation under heavy loads.
• Compact, reusable design for repeated service tasks.

Who is this for: The ZKTOOL Universal Ribbed Drive Crankshaft Pulley Puller Removal Tool Kit is geared toward professional technicians, independent mechanics, and informed DIYers who work on belt-driven engine accessories. If you regularly replace alternators, water pumps, AC compressors, or need to remove press-fit harmonic balancers in tight engine compartments, this kit provides a reliable, damage-conscious solution that saves time and avoids unnecessary part replacement.
