The BILITOOLS 15PCS Pulley Holder Tool Set is a compact, adjustable 1/2" drive pin-wrench kit designed to hold and turn camshaft and crankshaft pulleys securely during repair and replacement jobs.

This all-in-one kit groups an adjustable pin wrench, multiple interchangeable pins, a long 12-inch leverage wrench, spare adjusting nuts, and installation tools into a molded case so you can lock pulleys, apply torque, and remove stubborn components without improvising. Built for garages and mobile mechanics, the set covers a wide range of pulley diameters and pin hole sizes commonly found on cars and motorcycles.

How does this tool help when removing a stuck pulley?

The adjustable pin wrench locks into the pulley’s pin holes, preventing rotation while you apply torque with a breaker bar or ratchet. The included 12-inch wrench increases leverage so you can deliver higher turning force safely and with better control.

• Adjustable range: 32–127 mm (1¼"–5") to match different pulley diameters.
• Interchangeable pins: seven pin sizes (3.5–10 mm) to fit common hole patterns.
• 1/2" drive compatibility for use with standard breaker bars and ratchets.

Which pulley and vehicle types does the BILITOOLS set fit?

Designed for broad compatibility, the pin sizes and adjustable jaw range work with many camshaft, crankshaft, and accessory pulleys found on cars, light trucks, and motorcycles. The variety of pins handles small to medium pin-hole patterns without needing additional adapters.

• Pin sizes include 3.5, 4, 4.5, 5, 6, 7 and 10 mm for common pulley designs.
• Adjustable wrench covers pulleys from 32 mm up to 127 mm diameter.
• Suitable for both professional workshops and DIY maintenance.

What accessories come with the kit and why do they matter?

The set contains spare adjusting nuts and two small wrenches to make installation and future adjustments quick and reliable. A durable storage case keeps every piece organized and protected so the kit stays ready for the next job.

• Two replacement adjusting nuts to replace worn components on the go.
• Two small installation wrenches to secure pins and adjustments accurately.
• Sturdy molded case for transport and long-term storage.

How do I get the most torque without damaging parts?

Attach the 12" long wrench to a 1/2" drive ratchet or breaker bar to increase leverage, then let the pin wrench hold the pulley firmly while turning. Work in controlled increments and verify pin alignment to avoid slippage or damage to the pulley face.

• Use a 1/2" drive breaker bar or ratchet for added force.
• Ensure pins fully seat in pulley holes before applying torque.
• Increase torque gradually and re-check alignment after each attempt.
