Orion Motor Tech Harmonic Balancer Puller Kit — 49‑Piece Pulley & Steering Wheel Puller, Heat‑Treated Steel

The Orion Motor Tech OMT Harmonic Balancer Puller is a 49-piece gear and pulley removal kit designed to safely extract harmonic balancers, crankshaft pulleys, steering wheels, and other press-fit parts from most cars, trucks, and SUVs.

This all-in-one puller set provides the hardware, adaptors, and a heavy-duty yoke you need to remove pulleys and hubs without damaging surrounding components. Built from heat-treated AISI 1045 medium carbon steel with anodized centering adaptors and a chromed/blackened bolt selection, the kit balances durability with corrosion resistance for regular shop use. Its combination of SAE and metric bolts, plus a four-slot yoke that supports multiple configurations, makes it a practical addition to home garages and professional repair shops alike.

How does this kit remove harmonic balancers and pulley assemblies?

The kit uses a central pressure screw and a sturdy yoke to apply even extraction force while centering adaptors align with the pulley hub. Adapters and stepped bolts fit common crankshaft and pulley thread patterns so the pull force acts through the center rather than the pulley face, reducing the risk of distortion.

• Central pressure screw drives the puller to avoid side-loading
• Four-slot yoke converts for two- or three-slot operation
• Heat-treated centering adaptors ensure accurate hub alignment
• Stepped bolts included for GM 3300–3800 V6 1990+ crank pulleys

What sizes and fasteners are included for compatibility?

The OMT kit contains 30 bolts covering the most commonly encountered SAE and metric threads, along with three adaptors to match different hub diameters. This selection handles typical automotive tasks so you won’t need a separate bolt assortment for most jobs.

• SAE threads: 1/4"-28, 5/16"-18, 5/16"-24, 3/8"-16, 3/8"-24
• Metric threads: M8x1.25, M10x1.5
• Stepped bolts for specific GM crankshaft pulleys
• Three centering adaptors for varied hub sizes

Will this kit protect the parts I’m removing and the surrounding finish?

Yes. The puller’s yoke, pressure screw, and included washers distribute force evenly across the pulley to minimize marring or bending. The robust construction and correct adapter seating reduce the chance of slippage or off-center loads that can damage components.

• Even pressure distribution minimizes surface damage
• Washers and adaptors prevent direct metal-to-metal scoring
• Anodized adaptors provide smooth contact and added wear resistance
• Chrome and blackened bolts make identification fast and easy

How durable is the hardware for repeated shop use?

All main components are made from hardened AISI 1045 medium carbon steel and the centering adaptors undergo additional heat treatment and anodizing for extra strength. This construction is intended to withstand frequent use in professional garages or demanding DIY projects.

• AISI 1045 carbon steel yoke and pressure screw for strength
• Heat-treated, anodized adaptors resist wear and corrosion
• Chrome-plated SAE bolts and blackened metric bolts for longevity
• Design reduces risk of bending under high extraction forces

Who is this for? The Orion Motor Tech OMT Harmonic Balancer Puller kit is aimed at mechanics, restoration hobbyists, and DIY enthusiasts who need a single kit to remove harmonic balancers, crank pulleys, steering wheels, and similar press-fit parts across a wide range of vehicles. If you work on late-model GM V6 engines or maintain a mix of imported and domestic cars, this set supplies the thread sizes and adaptors you’ll reach for most often. It’s a practical, long-lasting tool kit for anyone who prefers to perform safe, controlled pulley removals without buying multiple specialty pullers.
