GEAROLL 15PCS Pulley Holder Tool Kit

GEAROLL's 15-piece pulley holder kit is an adjustable pin spanner wrench set with multiple pin sizes and a 1/2" drive connection that secures camshaft and crankshaft pulleys for removal and installation.

This comprehensive kit combines an adjustable pin wrench, a thin spanner, fourteen pins in seven sizes, and a plastic carrying case to tackle a wide range of pulley and harmonic balancer jobs. Constructed from heat-treated steel with corrosion resistance, the GEAROLL set expands from 32 mm to 127 mm (1-1/4" to 5") and links to a standard 1/2" drive ratchet or breaker bar for extra torque when loosening stubborn pulleys.

How does this kit fit different pulley sizes?

The wrench is adjustable across a broad span (32–127 mm) so it grips many common pulley diameters. Use the included variable pins to match hole spacing on camshaft, crankshaft, or fan clutch surfaces for a secure engagement.

• Adjustable jaw opening: 1-1/4" to 5" (32–127 mm)
• Seven pin sizes included: 3.5, 4, 4.5, 5, 6, 6.5, and 10 mm
• Thin spanner included for low-clearance or tight-access applications

Can I use this with my ratchet or breaker bar for extra torque?

Yes — the long pin wrench accepts a 1/2" drive connection so you can add a ratchet or breaker bar for increased leverage. That feature makes removing locked or corroded pulleys easier without resorting to improvised tools that can damage parts.

• 1/2" drive compatibility for standard hand tools
• Long handle design for extended reach and leverage
• Less chance of slipping compared with single-pin or improvised tools

Is the GEAROLL pulley holder durable and reliable for repeated shop use?

The kit is made from heat-treated steel and finished to resist corrosion, giving it the strength to withstand repeated torque and workshop conditions. Pins and the wrench body are designed to hold up under stress, reducing deformation and ensuring consistent engagement.

• Heat-treated steel construction for strength
• Corrosion-resistant finish for longevity
• Precision-fit pins minimize wear and slippage

What’s included, and how do I organize the kit for fast use?

The set arrives in a molded plastic case with dedicated slots so each pin and wrench fits securely and stays organized. That keeps the most-used sizes accessible and prevents loss of small pins during transport or storage.

• 14 pins (7 sizes) for accurate fit across many pulleys
• 1 x long 12" pin wrench and 1 x thin spanner for tight spots
• Plastic carrying case with molded compartments for each part

Who is this for: The GEAROLL 15PCS Pulley Holder Tool Kit is aimed at professional mechanics, DIY vehicle owners, and home garage enthusiasts who need a reliable, adjustable pin spanner for camshaft, crankshaft, harmonic balancer, and fan clutch work. It suits users who want a single kit that fits multiple engines and reduces the need for multiple dedicated wrenches, especially when higher leverage with a 1/2" drive is required.
