Adjustable three-jaw gear puller

This item is an adjustable three-jaw gear puller, a mechanical tool commonly used in automotive and industrial repair for removing press-fit parts such as gears, pulleys, or bearings. The tool features a central threaded steel bolt (power screw) surrounded by three articulating metallic arms, which appear to be constructed from forged steel with a polished or chrome-plated finish. The arms are secured with hexagonal bolts and nuts, allowing for adjustment to accommodate different workpiece diameters. One arm is clearly stamped with the text '8" - 200MM', likely indicating the maximum reach or spread capacity as marked by the manufacturer. The tool displays a metallic silver color with visible signs of utility, including minor surface oxidation (rust spots) on the threads and inside the stamped lettering, as well as scuffs and grease residue consistent with regular workshop use. The heavy-duty construction is consistent with 20th-century or early 21st-century mechanical tools. No specific manufacturer brand or logo is visible in the provided image; therefore, the identification is based on the functional design and common industry markings for this tool type.

I have examined the image of this 8-inch (200mm) three-jaw adjustable gear puller. Based on what I can see, the tool is a heavy-duty mechanical device featuring a chrome-plated or polished steel finish with stamped specifications. While the tool bears markings consistent with standard industrial sizing, I cannot identify a specific manufacturer from the photograph, as no brand name or logo is visible. The value estimate is based on the hypothesis that this is a professional-grade workshop tool of late 20th or early 21st-century manufacture. The presence of surface oxidation and grease suggests it has seen regular utility, which is common for this asset class. From a photo, I cannot verify the integrity of the power screw threads or the metallurgical composition, both of which are critical to safety and value; an in-person inspection would be required to ensure there are no stress fractures or stripped threads. In the current secondary market for used mechanical hand tools, items of this type generally command modest prices. If this item were found to be a premium professional brand (such as Snap-on or Proto), the value could increase toward the higher end of the range or slightly above. Conversely, if it is a generic mass-market reproduction or an 'in the style of' tool made from lower-grade cast alloys rather than forged steel, the value would likely drop below $20. To provide a more precise valuation, I would need to confirm the manufacturer and verify the structural soundness of the articulating joints and the center bolt under load.
