BILITOOLS Pulley Holder Tool Set — 15PCS Adjustable Pin Wrench, 1/2" Drive, 32–127mm Span, 7 Pin Sizes

The BILITOOLS 15PCS Pulley Holder Tool Set is an adjustable pin-wrench kit with a 1/2" drive that holds camshaft and crankshaft pulleys firmly so you can remove or install them with added reach and torque.

This purpose-built pulley holder combines an adjustable spanner arm, seven pinned inserts, a long wrench compatible with a 1/2" drive ratchet or breaker bar, and a compact storage case. Designed to work across many cars and motorcycles, the set gives you the pin configurations and leverage needed to lock pulley faces while you loosen or tighten fasteners, reducing slippage and protecting timing components during maintenance.

Which pulley sizes and pin diameters does this set fit?

The kit includes variable pins sized 3.5mm, 4mm, 4.5mm, 5mm, 6mm, 7mm and 10mm to cover a broad range of camshaft and crankshaft pulley holes. The adjustable wrench arm expands from 32mm (1 1/4") to 127mm (5"), letting you adapt to compact and larger pulleys without needing extra tools.

• Pin sizes: 3.5, 4, 4.5, 5, 6, 7, 10 mm for common pulley hole patterns.
• Adjustable span: 32–127 mm for small to medium pulleys.
• Compatibility: works on many cars and motorcycles with standard pin-hole pulleys.

How does the wrench give extra torque and reach?

The included 12" long adjustable wrench body accepts a 1/2" drive ratchet or breaker bar, which increases leverage so you can apply higher torque to stuck fasteners with less effort. The wrench swivels to set the correct angle, and replacement adjusting nuts maintain secure pin engagement during heavy-duty jobs.

• 12-inch wrench accepts 1/2" drive for added leverage.
• Swiveling jaw adjusts angles for tight engine bays.
• Two replacement adjusting nuts included for durable use.

What accessories and replacements come in the kit?

The set ships with seven pinned inserts, two small installation wrenches for the pins, two spare adjusting nuts, and a molded storage case. These extras let you swap pins quickly, keep everything organized, and replace wear parts without delay.

• Two small wrenches to install or remove pins easily.
• Two spare adjusting nuts for later maintenance or heavy use.
• Molded storage case keeps components protected and organized.

How do I use this tool safely on an engine pulley?

Position the correct pin pair to match the pulley hole pattern, tighten the adjustable arm so pins seat fully, then attach the 1/2" drive ratchet or breaker bar to the wrench. Apply steady force; avoid sudden jerks and always confirm timing marks and belt position before loosening engine pulleys.

• Select pin diameter and match pulley hole spacing precisely.
• Tighten adjusting nut securely before applying torque.
• Use steady, controlled force and re-check timing components after work.
