Motorcycle Main Shaft and Bearing Race Tool Kit for Big Twins

This appears to be a specialized tool kit, likely for motorcycle maintenance, specifically for addressing the main shaft and bearing races of 'big twins' as indicated by the context. The kit is housed in a simple, worn cardboard box, which bears handwritten notations 'June 2011' and '3/4', suggesting the date of acquisition, last use, or perhaps a part number for the box itself, and possibly a measurement or quantity. The tools themselves are constructed primarily from robust, dark-finished metal, likely steel, designed for heavy-duty use. The finish varies from a matte black to a dark grey, typical of industrial-grade tools, and shows signs of use and age, including scuffs, scratches, and some minor loss of finish, indicating a working patina rather than significant damage. There are several components visible: a large cylindrical puller or press tool with a prominent hexagonal nut at one end; two long, threaded rods with nuts and washers, suggesting they are part of a pulling or pressing mechanism; and a rectangular metal plate or block component, possibly a specialized adapter or support. The quality of craftsmanship appears high, with precisely machined threads and clean edges on the hexagonal nuts and cylindrical parts, which is essential for tools designed to exert significant force without failing. No specific maker's marks or detailed part numbers are clearly visible on the tools themselves, but the overall presentation suggests a professional-grade set, likely manufactured for a specific range of vehicle applications, as implied by the '620060 main shaft, bearing race tool, big twins' context. The tools show no signs of major damage or repair, but rather typical wear consistent with their function. Their substantial construction points to a design intended for durability and repeated use in mechanical applications.
