Yuesstloo Harmonic Balancer Puller Kit 59-Pc — Universal crankshaft pulley removal set, hardened forcing screw

The Yuesstloo 59-piece Harmonic Balancer Puller Kit is a full removal and installation solution designed to extract and fit crankshaft pulleys and harmonic balancers safely and with minimal engine interference.

If you work on passenger cars, light trucks, or perform routine engine maintenance, this kit collects the common thread sizes, studs, and a bearing-style forcing screw required to tackle most balancer jobs. The set combines metric and standard fasteners, a multi-slot bearing plate and washers, plus a hardened forcing screw so you can remove or reinstall pulleys without bending flanges or harming adjacent components. It ships with a hard case and gloves to keep parts organized and protect your hands while you work.

Which vehicles and pulleys does this kit fit?

The kit covers a wide range of crankshaft pulley and steering wheel applications thanks to multiple thread pitches and UNC/UNF screws. It is intended for many common Asian, European, and domestic engines, but not every model — double-check thread size compatibility before buying.

• Includes M16x2.0, M14x1.5, M12x1.5 plus 3/4-16, 5/8-18 and smaller UNC/UNF screws.
• Works for flywheel, crankshaft pulley, and steering wheel removal tasks on most vehicles.
• Not compatible with LT1 Gen 2 or certain 4.0L Chrysler engines; lacks M12x1.75 bolt.

How does the tool protect engine components during removal?

The set uses a thrust-bearing forcing screw and a six-way slotted bearing plate to distribute extraction force evenly and reduce side loading on the pulley. That design minimizes the risk of bent bolts or damaged pulley flanges, which helps preserve the crankshaft seal and surrounding hardware.

• Thrust bearing forcing screw provides smooth, centered pulling force.
• Slotted bearing plate lets you align multiple screw positions to spread the load.
• Assorted washers and hardened bolts prevent crushing or slipping during extraction.

What components are included and what should I verify before use?

The kit contains 59 pieces: a range of metric and inch threaded bolts, a forcing screw, bearing plate, washers, and a pair of gloves for safety. Before attempting removal, compare your vehicle’s pulley thread pitch and bolt length with the kit parts to confirm a proper match.

• Complete list includes M16, M14, M12 plus UNC/UNF screws and several M8/M10 studs.
• Comes with one forcing screw, one six-slot bearing plate, and five washers.
• Packaged in a molded case for organized storage and transport.

How durable and portable is this set for shop or mobile work?

All steel components are heat-treated and finished to resist rust and wear so the kit stands up to repeated professional or home-garage use. The molded carrying case keeps pieces secure and makes it easy to take the kit to roadside or fleet jobs.

• High-strength steel construction resists bending and corrosion.
• Compact case and labeled compartments for fast part selection.
• Includes gloves for safer handling during pulling and installation.

Who is this for: The Yuesstloo 59-piece Harmonic Balancer Puller Kit is aimed at DIY mechanics, independent shops, and fleet technicians who need a versatile removal and installation solution for a broad range of pulley types. If you routinely service crankshaft pulleys, steering wheels, or flywheels and need a portable, hardened set of adapters and a bearing-style forcing screw, this kit supplies most sizes you’ll encounter — just confirm compatibility with your specific engine model before ordering.
