BILITOOLS Pulley Holder Tool Set 15PC — 1/2" Drive Adjustable Pin Wrench, 12" Lever & 7 Pins

The BILITOOLS 15PCS Pulley Holder Tool Set is a versatile adjustable pin-wrench kit that secures and turns camshaft and crankshaft pulleys using a 1/2" drive for higher leverage and controlled removal.

This complete kit bundles an adjustable spanner, seven pin sizes, replacement hardware, and a durable storage case so you can lock pulleys in place or apply torque without damaging timing components. It was designed to fit a wide range of automotive and motorcycle pulley diameters and gives technicians and home mechanics a compact, organized solution for pulley service and replacement.

How does this set fit different pulley sizes?

The main adjustable wrench pivots to cover a broad diameter range and the kit includes seven pin sizes to match common pulley hole patterns. Pins insert into the pulley holes while the peripheral jaw holds the rim, giving secure contact to prevent slipping.

• Adjustable swing range: 32–127 mm (1 1/4"–5") to cover small to medium pulleys.
• Pin assortment: 3.5, 4, 4.5, 5, 6, 6.5 and 10 mm for varied hole spacing.
• Replacement adjusting nuts included for continued use and longevity.

Can I use this with a breaker bar or ratchet for stubborn pulleys?

Yes — the tool accepts a 1/2" drive connection so you can attach a ratchet or breaker bar for added leverage. The 12-inch wrench length increases reach and torque, helping to free seized or tightly fitted pulleys without forcing the pulley or damaging fasteners.

• 1/2" drive compatibility for standard breaker bars and ratchets.
• 12-inch long wrench for improved leverage and clearance in tight engine bays.
• Robust connection point built to withstand higher torque inputs.

What comes in the kit and how is it stored?

The BILITOOLS kit delivers a complete set of pins, installation hardware, two small helper wrenches, and a rigid carrying case. Everything snaps into place so tools stay organized, protected, and ready to transport between jobs or stored in a garage drawer.

• 15-piece assortment: adjustable spanner, seven pins, two replacement nuts, two small wrenches, and accessories.
• Sturdy molded case keeps parts separated and prevents loss.
• Compact footprint designed for workshop shelves, trunks, or tool cabinets.

Will this set protect pulleys and components during service?

The design focuses on secure engagement and controlled force application to reduce the risk of slipping or marring pulley surfaces. Using correct pin size and the adjustable jaw alignment helps distribute load correctly, minimizing impact on timing or accessory components.

• Select the correct pin diameter for a tight, wobble-free fit in pulley holes.
• Adjust jaw span so the rim contacts evenly and avoids edge gouging.
• Use 1/2" drive tools for measured torque instead of ad-hoc levers that can slip.

Who this is for: The BILITOOLS 15PCS Pulley Holder Tool Set is aimed at professional mechanics, automotive hobbyists, and motorcycle technicians who need a reliable, compact pulley-holding solution. If you service camshaft or crankshaft pulleys, perform timing work, or frequently remove accessory pulleys, this set supplies the pin sizes, leverage option, and organized case to make those jobs faster and safer.
