ZKTOOL Ribbed Drive Pulley Puller Kit, 35-160mm Range — Low-Profile Arms & 3 Reversible Claws

The ZKTOOL Universal Ribbed Drive Crankshaft Pulley Puller Kit is a heavy-duty, adjustable tool set built to remove V-ribbed belt pulleys from 35mm to 160mm diameter without damaging components.

This professional-grade puller kit gives mechanics and DIYers a safe, controlled way to extract crankshaft harmonic balancers, alternator pulleys, air conditioning unit pulleys, and water pump pulleys that are press-fit or otherwise stubborn. With low-profile arms, reversible claws, and a robust forcing screw that works with a 17mm wrench or 3/8" square drive tool, the set is engineered to fit tight engine bays and resist slipping while under tension. The puller’s adjustable range and durable construction make it a versatile addition to any automotive tool chest.

How does this puller remove pulleys without causing damage?

The kit uses adjustable claws that grip the pulley evenly and a central forcing screw that applies steady, aligned pressure to extract the pulley straight off the shaft. Locking bolts help secure the arms so they won't shift while you turn the forcing screw, reducing the risk of marring the pulley or shaft.

• Three reversible, adjustable claws for even grip across different pulley profiles
• Locking bolts hold arms in place to prevent slippage
• Central forcing screw aligns pull force to avoid bending or twisting parts
• Works with standard 17mm wrench or 3/8" drive ratchet for controlled torque

Which pulley sizes and vehicle parts are compatible with this kit?

The ZKTOOL puller covers V-ribbed belt pulleys with diameters from 35mm up to 160mm, making it suitable for many automotive and small-engine applications. It’s specifically designed for crankshafts, alternators, AC compressor pulleys, and water pump pulleys that are pressed or tightly fitted.

• Compatible pulley diameter: 35mm–160mm
• Common uses: crankshaft harmonic balancer, alternator, AC, water pump
• Fits thin-profile pulleys and deeper-set pulleys via adjustable arm positions
• Works on both repair-shop and home-project vehicles when access is limited

What makes this puller usable in tight engine bays and awkward positions?

Low-profile arms and a compact forcing screw mean the puller can be positioned where bulkier tools won’t fit. The arms are designed to clear surrounding components and still deliver the leverage needed to remove stubborn pulleys without removing additional engine parts first.

• Low-profile arm design for narrow clearance use
• Adjustable claw reach to fit recessed pulleys
• Detachable parts allow reconfiguration to suit confined spaces
• Durable surfaces resist deformation when used at unusual angles

What tools and technique do I need to use this kit safely?

Use a 17mm wrench or a 3/8" square drive ratchet to turn the forcing screw steadily; avoid sudden, high-impact force. Position the claws evenly, tighten locking bolts, and turn the screw gradually while checking alignment to ensure a straight pull.

• Required drive tools: 17mm wrench or 3/8" square drive ratchet
• Tighten locking bolts after claw placement to prevent slipping
• Apply steady torque; avoid hammering the forcing screw
• Inspect threads and contact points periodically during use

Who is this for? The ZKTOOL Universal Ribbed Drive Pulley Puller Kit is aimed at professional mechanics, automotive technicians, and experienced DIY enthusiasts who work on engines with V-ribbed belt systems. If you regularly service alternators, crankshafts, AC compressors, or water pumps and need a dependable, compact puller that minimizes collateral damage and saves disassembly time, this kit fits the bill. Its adjustable range and rugged build make it a practical tool for busy shops and well-equipped home garages alike.
