Whether you are performing a top-end refresh or a complete block rebuild, the TM1087 ensures your engine meets original OEM performance curves.

Hydraulic System and Pump Reconstruction

Vintage hydraulic systems require a careful hand and exact seal specifications to prevent internal bypass. This section features exploded views of the main hydraulic pump and the multi-spool control valves. It provides the seal-replacement logic and wear-plate resurfacing specs required to eliminate cylinder drift, ensuring your loader and backhoe respond with the breakout force they had when they first left the factory.

Drivetrain and Wet-Disc Brake Restoration

The 300B’s drivetrain is engineered for constant shifting and rugged transport. The TM1087 governs the internal repair of the transmission, differential, and internal wet-disc braking systems. It includes the vital shim-selection mathematics and bearing preload targets required to ensure the final drives can handle the stress of heavy transport without excessive heat or gear wear.
