Jiimee Pulley Holder Tool Kit 15pc — 12-inch Pin Wrench with 7 Pin Sizes, Chrome Vanadium

Jiimee 15pcs Pulley Holder Tool Kit is a heavy-duty adjustable pin wrench set designed to safely hold and remove camshaft and crankshaft pulleys with interchangeable steel pins and a long reach wrench.

This kit combines a robust 12-inch pin wrench, seven sizes of hardened steel pins, and a compact carrying case to give mechanics and DIYers a reliable way to secure and turn pulleys during engine work. Built from chrome vanadium alloy and heat-treated for hardness, the components are intended to withstand high torque when paired with a standard 1/2-inch drive ratchet or breaker bar. The pins span a broad diameter range, and the wrench’s swivel adjustment accommodates multiple pulley sizes, making it a versatile addition to any automotive tool set.

How will this kit help when removing locked or seized pulleys?

The long 12-inch pin wrench provides extra leverage, letting you apply steady torque while the hardened steel pins engage pulley holes or slots securely. Using a breaker bar or ratchet on the wrench reduces the risk of slipping and damaging the pulley face.

• 12-inch (30.5 cm) wrench for increased leverage and control
• Pins fit pulley holes from 3.5 mm to 10 mm to match common sizes
• Use with a 1/2-inch drive ratchet or breaker bar for higher torque

What makes the Jiimee pins and wrench durable enough for workshop use?

All steel parts are forged from chrome vanadium alloy and then heat-treated to a specified hardness range, providing resistance against bending and wear under torque. The adjustable swivel mechanism on the wrench maintains a tight grip on the pulley, helping distribute force evenly and lowering the chance of tool deformation.

• Chrome vanadium construction for strength and longevity
• Heat-treated to HRC50–55 hardness for wear resistance
• Swivel-adjustable wrench ensures firm, centered engagement

Which pulley and crankshaft types are compatible with this set?

The kit covers a wide variety of camshaft and crankshaft pulley designs by offering fourteen steel pins across seven diameters and an adjustable jaw range. It’s intended for most pulleys that accept pin engagement, but compatibility depends on the pulley’s hole spacing and layout.

• Pins sized from 3.5 mm up to 10 mm to match common hole sizes
• Wrench adjusts from 1-1/4" to 5" (32–127 mm) to fit multiple pulley diameters
• Ideal for pulleys with drill or slot-style engagement points

How portable and organized is the kit for on-the-road repairs?

The set arrives in a molded plastic case that keeps pins and wrench secure and easy to find. The compact footprint fits into most toolboxes and trunk compartments, making it practical for mobile mechanics and home garages alike.

• Plastic carrying case for neat storage and transport
• All 14 pins and the wrench stow in dedicated slots to prevent loss
• Lightweight enough for road-side or shop use
