Orion Motor Tech Harmonic Balancer Puller Kit, 49-piece

Technical details

Home mechanics and automotive repairers who need to remove pulleys or steering wheels may appreciate having several puller components in one case. The Orion Motor Tech kit is a 49-piece set built around a steel yoke and pressure screw, with adaptors, washers and bolts in SAE and metric sizes. Its four-slot yoke can be arranged for two- or three-slot operation, so it offers more flexibility than a single-purpose puller.

The set includes bolts in 1/4"-28, 5/16"-18, 5/16"-24, 3/8"-16, 3/8"-24, M8x1.25 and M10x1.5 sizes. The yoke and pressure screw are made from hardened AISI 1045 medium-carbon steel, centring adaptors are heat-treated and anodized. Metric bolts are blackened, while SAE bolts are chrome-plated, which helps distinguish the two groups when selecting hardware.

Compatibility and requirements

The kit is intended for universal harmonic balancers, gear pulleys, steering wheels and crankshaft pulleys, and is described as suitable for most cars, pickups and SUVs. It also includes stepped bolts for 1990 and newer GM 3300–3800 V6 crankshaft pulleys. That stated coverage is broad, not a guarantee of fit for every vehicle or pulley arrangement. The supplied information does not list vehicle-specific fitments, so match the application and fastener requirements before starting work.

This may interest you if you handle more than one type of pulley and would rather keep a range of puller hardware together than buy a tool for each job. As designed, the yoke and washers distribute pressure across the pulley to help avoid scratches during removal. They do not remove the need to position the tool correctly and apply pressure carefully.

Usage tips

For a practical example, when removing a crankshaft pulley, first identify its available holes and select bolts that match their size and thread. Set the yoke for the relevant two- or three-slot arrangement, then centre the pressure screw and use the washers as intended to spread contact. Keep the hardware organised by SAE and metric type, the different finishes make sorting easier, but do not replace checking the thread.

Use the kit only where its arrangement and included hardware suit the component. If your repair calls for an application-specific puller or a fitment not covered by the listed sizes, a dedicated tool may be the more suitable approach. This may not be the best choice if you need confirmed compatibility for a particular vehicle, since the product details do not provide a complete fitment list.

Before you decide

What can the kit remove? It is listed for harmonic balancers, gear pulleys, steering wheels and crankshaft pulleys.

Does it include both SAE and metric bolts? Yes. The set includes the listed SAE and metric sizes, with the two groups finished differently for easier identification.

Is it confirmed to fit every car or SUV? No. The description says it works on most cars, pickups and SUVs, and names a specific GM V6 pulley application, but does not confirm every vehicle.

Before buying

Choose this set when having multiple puller configurations and bolt sizes on hand matters more than a confirmed vehicle-specific match. Its breadth is useful for varied repair tasks, while the main limitation is that the listed coverage does not establish fit for every pulley. For a single known job, compare the included threads and yoke arrangement with that pulley before relying on the kit.
