Whether you’re performing routine maintenance, a component overhaul, or on-the-spot diagnostics, this manual helps you confirm the exact parts, reduce guesswork, and streamline ordering. You can view it on a computer, tablet, or printed in the workshop to guide disassembly and reassembly with confidence.

What’s inside the Parts Book

The Parts Book presents a comprehensive, component-by-component reference designed to support accurate repairs and efficient parts management. Expect detailed exploded-view diagrams and clear labeling that shows how assemblies fit together, plus the corresponding OEM part numbers and cross-references to help you locate exact replacements quickly. It covers major subsystems within the SAA6D108E-2 engine and its associated components, including:

• Engine block, cylinder head, pistons, and associated hardware
• Fuel system components (fuel pump, injectors, rails, rail-to-tuel connections)
• Lubrication and cooling subsystems (pumps, radiators, thermostats, hoses, seals)
• Air intake, exhaust, and turbocharger assemblies
• Electrical harnesses, sensors, actuators, and related connectors
• Ancillary equipment and mounting hardware

The manual typically includes assembly and disassembly notes, service procedures, and where applicable torque specs or fastener guidelines to ensure proper reassembly. It also features a detailed index and cross-reference tables to simplify navigation between parts numbers and their corresponding diagrams. Because it is tailored to the Japan-market configuration, you’ll find references that reflect the specific fitment and part numbers used in S/N 19030-UP machines.
