Orion Motor Tech harmonic balancer and gear puller kit — 49-piece set, hardened AISI 1045 steel yoke

Orion Motor Tech's 49-piece harmonic balancer and gear puller kit removes steering wheels, crankshaft pulleys, harmonic balancers, and other press-fit parts quickly and safely.

This all-in-one puller kit brings workshop-grade components to home garages and professional bays. Built from hardened AISI 1045 medium carbon steel with heat-treated, anodized centering adaptors and a four-slot yoke for two- or three-slot use, the set is engineered for repeated service. It includes a wide selection of SAE and metric bolts and built-in compatibility for many late-model GM crankshaft pulleys, making it a versatile choice for general automotive maintenance and pulley removal jobs.

How does this kit make pulley and steering wheel removal easier?

The kit centralizes necessary puller hardware into one set so you don’t hunt for separate bolts or adaptors. The yoke and pressure screw deliver controlled, even force to avoid marring metal surfaces, and the included centering adaptors ensure accurate alignment for smooth extraction.

• Four-slot yoke supports two- or three-slot configuration for varied pulleys
• Pressure screw and washers distribute load evenly to prevent scratches
• Centering adaptors align on hubs and balancers for straight pulls
• Stepped bolts included for 1990+ GM 3300–3800 V6 cranks

What components are included, and which sizes are covered?

The set contains a steel yoke, a heavy-duty pressure screw, three centering adaptors, and 30 bolts in common SAE and metric sizes for broad compatibility. Bolt threads cover 1/4"-28, 5/16"-18, 5/16"-24, 3/8"-16, 3/8"-24, M8x1.25, and M10x1.5 to match most pulleys and hubs you’ll encounter.

• 49 total pieces: yoke, pressure screw, 3 adaptors, 30 bolts, washers, and hardware
• SAE and metric thread options for domestic and import vehicles
• Step bolts catered to GM 3300–3800 V6 cranks (1990 and newer)
• Packaged for quick selection of the correct bolt and adaptor

How durable is the tool kit, and how does it resist corrosion?

Critical load-bearing parts are machined from AISI 1045 medium carbon steel for strength and toughness under repeated loads. The centering adaptors receive additional heat treatment and anodizing to increase wear resistance, while metric bolts are blackened and SAE bolts are chrome-plated for quick identification and improved corrosion protection.

• AISI 1045 hardened steel body withstands sustained mechanical stress
• Heat-treated, anodized centering adaptors for extra durability
• Chrome-plated SAE bolts and blackened metric bolts for corrosion resistance
• Robust pressure screw designed to endure repeated high-torque pulls

Will this kit prevent damage to delicate pulleys and steering components?

Yes — the design emphasizes non-marring removal by spreading force across the yoke, pressure screw, and included washers. Properly selected adaptors and bolts center the tool and keep axial load straight so parts come off cleanly with minimal risk of surface damage.

• Even pressure distribution reduces the chance of scratches or dents
• Washers and pressure screw minimize point loading on pulleys
• Centering adaptors align pulls to avoid side-loading and binding
• Multiple bolt sizes help fit OEM and aftermarket pulleys accurately

Who is this for: This Orion Motor Tech puller kit is suited for DIY mechanics, home enthusiasts, and professional technicians who need a reliable, all-purpose harmonic balancer and gear puller. If you service cars, pickups, or SUVs and encounter various pulleys, steering wheels, or crankshaft components, the OMT 49-piece set supplies the thread sizes, adaptors, and hardened hardware to complete the job efficiently and with minimal surface damage.
