ZKTOOL Universal Ribbed Pulley Puller Kit — 35–160mm Low-Profile Crankshaft & Harmonic Balancer Removal, Adjustable Claws

The ZKTOOL Universal Ribbed Drive Crankshaft Pulley Puller Removal Tool Kit is a heavy-duty, adjustable puller designed to remove V-ribbed belt pulleys and harmonic balancers from 35mm to 160mm without damaging the part or shaft.

This kit gives mechanics and DIYers a compact, reliable way to extract press-fit drive pulleys from crankshafts, alternators, AC compressors, and water pumps. Engineered for low-clearance work and repeated shop use, the set pairs adjustable claws with locking bolts and a center forcing screw that accepts common 17mm wrenches or 3/8" square drives.

How does this puller protect pulleys and shafts during removal?

Its dual adjustable claws distribute pulling force evenly around the pulley edge to prevent bending or scoring. Locking bolts secure the claws in place so the assembly won’t shift under load, reducing slip and accidental marring.

• Adjustable claws grip both inner and outer edges to avoid concentrated stress points
• Locking bolts hold the claws steady while the forcing screw applies pressure
• Durable steel construction stands up to high torque without deforming

Will this work in tight engine bays and limited-clearance situations?

The kit’s low-profile pulling arms and compact forcing screw were designed for confined spaces where larger pullers won’t fit. You can position the tool behind fan shrouds or between accessory brackets without needing to disassemble surrounding components.

• Low-profile arms clear nearby brackets and housings
• Short forcing screw reduces required swing room for wrenches or ratchets
• Works with both right- and left-side access configurations

What pulley sizes and vehicle components are compatible?

The puller covers a wide diameter range so it handles most V-ribbed belt pulleys and many harmonic balancers found on passenger cars, light trucks, and small industrial equipment. It’s intended for service tasks on crankshafts, alternators, air conditioning compressors, and water pumps.

• Fits pulleys from 35mm up to 160mm in diameter
• Compatible with V-ribbed belt pulleys and many press-fit harmonic balancers
• Suitable for crankshaft, alternator, AC unit, and water-pump pulleys

What tools and technique are needed to use the kit safely?

Install the claws around the pulley lip, tighten the locking bolts to hold position, and use a 17mm wrench or a 3/8" square-drive ratchet on the center forcing screw to extract the pulley gradually. Apply steady, even turns; stop and re-check alignment if the puller binds or the claws shift.

• Center forcing screw accepts 17mm wrench or 3/8" drive tools
• Tighten incrementally to keep pulling even and prevent sudden release
• Inspect claws and locking bolts before each use for secure engagement

Who is this for: The ZKTOOL Universal Ribbed Drive Crankshaft Pulley Puller Removal Tool Kit is aimed at professional mechanics, mobile technicians, and committed DIY enthusiasts who service drive accessories and need a compact, damage-minimizing puller. If you routinely remove press-fit pulleys from confined engine bays or want a versatile shop-ready puller for pulleys between 35mm and 160mm, this kit provides durable parts and practical compatibility for repeated automotive and light-industrial jobs.
