Tschudin HTG-300 Parts Manual – 27-Page Technical Reference with 25 Detailed Drawings

The Tschudin HTG-300 Parts Manual is a critical resource for rebuilders, machine tool technicians, grinders, and restoration specialists working with the Tschudin HTG-300 cylindrical grinder. This professionally reproduced 27-page manual contains 25 factory mechanical drawings, each clearly labeled with part numbers—including bearing part numbers—to support accurate identification, ordering, and assembly work. Whether you are restoring an older machine, performing a full mechanical rebuild, or diagnosing component-level issues, this manual provides the technical clarity needed to keep your HTG-300 performing at factory standards.

More comprehensive than a standard operator’s manual, this parts reference includes detailed mechanical breakdown drawings for all major assemblies, including the work head, grinding spindle, cross slide, lubrication lines, coolant routing, and hydraulic components. The manual also contains multiple hydraulic-related schematics essential for diagnosing oil flow, valve operation, and integrating the hydraulic controls with the electrical system.

Importantly, this manual includes a unique hydraulic-switch schematic—a diagram different from the version provided in the operator’s manual—which shows the hydraulic switches, their relationship to the controls, the connected electrical elements, and the remainder of the hydraulic section. Both this unique schematic and the standard hydraulic schematic (identical to the one found in the operator’s manual) are included for cross-reference and troubleshooting accuracy.

Please note: The foundation drawing listed in the index is missing from the original source and is not included.
