syizyen Harmonic Balancer Puller Set 46‑Piece — 4‑Slot Yoke, Hardened Forcing Screw, 30 Bolts

The syizyen 46PCS Harmonic Balancer Puller Set is a complete 4‑slot puller kit with 30 bolts and hardened components for removing harmonic balancers, crank pulleys, steering wheels and gears on most cars and light trucks.

This all‑in‑one pulley puller kit combines a heavy‑duty four‑slot yoke, a heat‑treated center forcing screw, three adapters and a wide selection of bolts in common SAE and metric threads. Designed for mechanics and DIYers who service engines, this set gives you the thread sizes and hardware to match most factory pulley and flywheel attachments so you can extract parts cleanly without damaging the hub or surrounding components.

How does this puller kit fit different vehicles?

The syizyen kit is built for broad compatibility by including 30 bolt sizes and a flexible 4‑slot yoke that accepts multiple bolt patterns. The assortment covers common threads used on passenger cars, light trucks and small engines so you rarely need extra hardware when switching between jobs.

• Included thread sizes: 1/4"‑28, 5/16"‑18, 3/8"‑24, 3/8"‑19, 3/8"‑16, M8x1.25, M10x1.5
• Four‑slot yoke adapts to varied bolt spacings and center bores
• Three adapters extend reach for deeper or recessed pulleys

What materials and build quality can I expect?

Key load parts use strong carbon steel with heat treatment on the center adapter and hardened forcing screw to resist bending and wear. Corrosion resistance and toughness mean the kit can stand up to regular shop use and the torque demands of pulley removal without deforming.

• Carbon steel construction for the yoke and bolts
• Hardened forcing (pressure) screw for repeated use
• Heat‑treated center adapter to maintain alignment under load

How do you use the 46‑piece crank pulley puller safely and effectively?

Using the set is straightforward: match a bolt to the threaded hole in the pulley, attach the yoke and bolts, fit the center screw or adapter, then turn the forcing screw evenly to draw the pulley off its shaft. Work slowly and keep the tool centered to avoid slippage or damage to the hub, and select the bolt size that threads fully into the component for a secure pull.

• Find and clean the pulley’s threaded holes before attaching bolts
• Use the correct adapter to center the forcing screw on the shaft
• Apply steady, even torque to extract the pulley without impact tools

What applications does this kit handle beyond harmonic balancers?

Beyond harmonic balancers, the kit removes crankshaft pulleys, steering wheels, gears and flywheels where threaded attachment points exist. Its variety of bolt lengths and threads plus the adaptable yoke make it useful for engine work, steering column service and small engine maintenance.

• Steering wheel and steering column component removal
• Crankshaft and accessory pulley extraction
• Small engine and light truck flywheel or gear removal

Who this tool set is for: the syizyen 46PCS Harmonic Balancer Puller Set suits professional mechanics, mobile technicians and dedicated DIY vehicle owners who need a durable, versatile puller that covers common SAE and metric threads. If you perform routine engine or steering repairs across different makes and models, this kit reduces trips to the parts store and helps you remove stubborn pulleys and hubs cleanly. It’s not a specialty tool for a single model but a broad‑use kit intended to save time and protect components during removal operations.
