Tschudin HTG-400 Parts & Hydraulics Manual – 28-Page Technical Reference with 26 Detailed Drawings

The Tschudin HTG-400 Parts and Hydraulics Manual is an essential resource for rebuilders, maintenance technicians, machine tool restorers, and precision grinding specialists working with the Tschudin HTG-400 cylindrical grinder. This comprehensive 28-page manual includes 26 factory drawings, each clearly labeled with part numbers—including bearing part numbers—for accurate ordering, servicing, and overhaul work. Whether you are restoring a machine, troubleshooting hydraulic issues, or rebuilding assemblies, this manual provides the precise technical details needed to maintain peak performance.

This manual delivers a deeper level of detail than the standard operator’s manual, offering expanded hydraulic schematics, mechanical breakdown drawings, and component-level illustrations. The collection includes full diagrams for major systems such as the work head, grinding spindle, lead spindle, lubrication pathways, coolant system, and the full hydraulic command block arrangement. It is especially valuable for machine rebuilders who need accurate hydraulic routing, switch logic, and part identification not often found in general operation guides.
