00 – Index and Foreword

The opening chapter establishes the framework for the entire manual. It includes a comprehensive abbreviation list covering both text and circuit diagram terminology, safety notices for operation, precautions to prevent fire, actions if fire occurs, precautions for disposing of waste materials, and actions taken to meet exhaust gas regulations. It also details precautions for DEF handling, storage of AdBlue/DEF, handling of hydraulic equipment, disconnection and connection of pipings, handling of electrical equipment, fuel system equipment, and intake system equipment. The chapter explains how to read the engine shop manual, how to read electrical wire codes, the explanation of terms for maintenance standards, a standard tightening torque table, and conversion tables. This section ensures that anyone using the manual understands the safety requirements, symbols, and conventions used throughout.

01 – Specifications

This chapter provides the complete specifications for the SAA6D170E-7 engine as used in the WA600-8. It begins with an abbreviation list specific to the specifications section, followed by the engine specifications. Key figures include the 6-cylinder, 170 mm x 170 mm bore and stroke, 23.15 L (23150 cc) piston displacement, and firing order 1-5-3-6-2-4. The chapter lists overall dimensions, rated horsepower of 396 kW (531 HP) at 1800 rpm, maximum torque of 2594 Nm (264.5 kgm) at 1100 rpm, maximum no-load speed of 2000±25 rpm, minimum no-load speed of 800±25 rpm, and fuel consumption ratio at rated horsepower of 227 g/kWh (169 g/HPh). It also covers dry weight, fuel injection system type, control system type, lubricating oil and coolant capacities, alternator and starting motor specifications, and turbocharger model. An engine general view provides a left side view illustration with dimensional references, and a weight table breaks down component weights for the major engine assemblies. The engine performance curve completes the chapter with graphical data for torque and horsepower across the operating range.

10 – Structure and Function

This is the largest technical chapter in the manual, covering the structure and operation of every major engine system. It opens with an abbreviation list and then systematically covers the Urea SCR system, including its layout drawing, system diagram, function, and component parts such as the AdBlue/DEF mixing tube, SCR assembly, AdBlue/DEF tank, tank sensor, pump, injector, hose, and tank heating valve. The engine system section provides a layout of engine components, intake and exhaust system parts, engine main body parts, the KVGT system, lubrication system, fuel system, cooling system, and electrical system. Each system is presented with detailed diagrams, cross-sectional illustrations, and explanations of how the components interact. The KVGT system, for example, includes the control system diagram, lubrication and cooling details, and the operation of the hydraulic actuator. The fuel system covers the CRI system, supply pump, common rail, flow damper, pressure limiter, common rail pressure sensor, and injector operation. The electrical system covers the alternator, starting motor, engine wiring harness, engine controllers, and every sensor used on the engine. This chapter is essential for understanding how the engine and its subsystems operate before performing diagnostics or repairs.

20 – Standard Value Table

The Standard Value Table chapter provides the performance and specification benchmarks for the SAA6D170E-7 engine. It includes a standard value table for the engine covering performance parameters such as engine speed, air intake and exhaust system values including air intake resistance, boost pressure, exhaust temperature, exhaust gas color, valve clearance, EGR valve oil pressure and KVGT oil pressure. It also covers main body values including compression pressure and blowby pressure. Lubrication system values include engine oil pressure at rated horsepower and low idle, engine oil temperature, and oil consumption. Electrical system values cover alternator belt tension. A separate section provides running-in standards and performance test standards, with procedures, engine speeds, dynamometer loads, output figures, torque values, fuel consumption, coolant temperature, lubricating oil temperature and pressure, and exhaust temperature. This chapter is used to determine whether the engine is performing within specification and to guide testing and adjustment procedures.

50 – Disassembly and Assembly

This chapter provides the complete procedures for disassembling and assembling the engine, both generally and for specific components. It begins with an abbreviation list, related information on disassembly and assembly, how to read the manual, a coating materials list, a special tools list, and sketches of special tools. The engine system section covers the general disassembly and assembly of the engine, including preparation, draining coolant and oil, removing the starting motor, KVGT assembly, EGR cooler, EGR oil pump, tension pulley, damper assembly, engine controller, supply pump, belt, alternator, engine oil pan, air conditioner compressor, KCCV, water pump, rocker arm assembly, exhaust manifold, head cover, shaft assembly, flywheel, flywheel housing, oil cooler, wiring harness assembly, push rod, injection drive gear, cylinder head assembly, fuel prefilter, cam follower cover, supply pump drive assembly, front cover, fuel filter, cam follower, oil filter, high pressure pipe, common rail, intake manifold, EGR valve, camshaft, rear side idler gear, piston cooling nozzle, piston and connecting rod assembly, crankshaft, cylinder liner, front side idler gear, and engine oil pump. Each procedure is presented step by step with tightening torques, coating materials, and special tools identified. Separate sections cover removing and installing the supply pump assembly, engine front oil seal, and engine rear oil seal. This chapter also includes a comprehensive check for fuel leakage after reassembly.

60 – Maintenance Standard

The Maintenance Standard chapter provides the judgment criteria for determining whether components can be reused or must be replaced or repaired. It covers the intake and exhaust system parts with maintenance standards for the KVGT, including radial play, end play, and operation check. The engine main body parts section covers the cylinder head, cylinder block, cylinder liner, crankshaft, cam follower and push rod, piston, connecting rod, vibration damper, timing gear, camshaft, valve and valve guide, rocker arm, crosshead and guide, and flywheel. Each component is presented with standard dimensions, tolerances, repair limits, and allowable clearances or interferences. The lubrication system section covers the relief valve of the engine oil pump, relief valve of the engine boost oil pump, and safety valve of the engine oil filter. The cooling system section covers the oil cooler, water pump, and thermostat. This chapter is essential for anyone performing a rebuild or overhaul, as it provides the measurable criteria that determine whether a part is within specification or must be replaced.
