Component and System Indexing

Finding the right hardware during a teardown shouldn't stall your workflow. This catalog breaks down tractor assemblies into ten core groups, starting with general service tools and moving through the D358 engine, fuel delivery, electrical loops, and steering linkages. It maps out the entire power train, braking, hydraulic circuits, and chassis.

When rebuilding a hydraulic pump or swapping a clutch, the exploded-view diagrams accurately identify every fastener, gasket, and seal. These visuals tie directly to numerical indexes and descriptive tables, ensuring you order the exact replacement components. Before beginning any heavy disassembly, always ensure hydraulic pressure is fully relieved and verify hardware load ratings against the factory specifications listed in these diagrams.

Specifications and Technical Data Preview

This documentation goes beyond basic part numbers by providing critical hardware sizing—including M6, M8, M10, 5/16-inch, and 1-inch bolt dimensions—to save time at the parts bin.

If you are troubleshooting the cooling loop or upgrading the charging system, you will find detailed radiator housing layouts, fan configurations, and mounting schematics for 55A alternators with their specific tensioner brackets. The catalog also details diagnostic tool pressure gauge references ranging from -1 to 250 kp/cm2, giving mechanics the exact original parameters needed for proper system evaluation and parts replacement.
