Motorcycle Main Shaft Bearing Race Tool Kit

This appears to be a specialized tool kit, likely for motorcycle maintenance, specifically related to the '620060 main shaft bearing race' found in 'big twins' (referencing Harley-Davidson motorcycles). The kit consists of several components, all seemingly made of hardened steel with a dark, possibly black oxide or blued finish, indicating durability and rust resistance for garage environments. Key components include: 1. A C-shaped plate with two drilled holes, consistent with a puller or press plate, measuring approximately 0.5 inches thick. Its purpose is to provide leverage or a stable point for attachment. 2. A long threaded rod with a hex head bolt at one end and threading along most of its length. This is a central pulling or pushing screw, essential for applying force. 3. A T-handle or cross-bar puller mechanism, consisting of a heavy, rectangular block with a threaded bore through its center and another perpendicular bore through which a smaller, possibly unthreaded, rod can pass. This acts as a fixed point or a bracing component for extracting or installing parts. 4. A large, cylindrical hollow tube or sleeve, open at both ends, with a large hex nut at one end. This sleeve would likely be used to house a bearing or act as a guide/press in conjunction with the threaded rod. 5. Another long threaded rod, similar to the second item but potentially with different threading or length, and a distinct end fitting (possibly a smaller hex or shoulder). All components exhibit some signs of use, including minor scuffs, light surface scratches, and possibly faint greasy residue, which is typical for workshop tools. The surfaces are generally clean, suggesting regular maintenance or recent use. There are no visible signs of significant damage such as bends, cracks, or heavy corrosion, indicating the tool is in good working condition. The uniformly dark finish suggests they are intended to be a cohesive set. The robust construction and precise machining (evidenced by clean threads and mating surfaces) point to a high-quality, professional-grade tool designed for specific, high-force applications. The lack of specific manufacturing marks in the visible areas makes it hard to pinpoint a brand or exact age, but its robust nature suggests it's built to last.
