Specification

This chapter provides the outline, specifications, general view, weight table, and engine performance curves for the SAA4D95LE-5-A and S4D95LE-3 engines. It lists rated output, maximum torque, no-load speeds, fuel consumption ratios, dry weight, lubricating oil and coolant capacities, and the fuel supply pump and governor type. Performance curves show flywheel horsepower and torque across the engine speed range for both FD40Z-10/FD35-10/FD40-10/FD45-10/FD50A-10 and FD60-10/FD70-10/FD80-10 machine groups.

Structure, Function and Maintenance Standard

This is the largest chapter, covering the general structure, air intake and exhaust system, turbocharger, engine unit, cylinder head, cylinder block, cylinder, main moving parts, crankshaft, camshaft, piston, piston ring, piston pin, connecting rod, flywheel and flywheel housing, timing gear, valve system, lubrication system, oil pump, regulator valve, oil filter, fuel system, supply pump, fuel injection nozzle, fuel filter, common rail, various sensors, cooling system, water pump, cooling fan drive, thermostat, electrical equipment, starting and charging system, alternator, starting motor, starting aid, and engine controller. Each section includes detailed diagrams, maintenance standards, repair limits, and standard clearances.

Standard Value Table

The standard service value table for testing, adjusting, and troubleshooting lists performance, intake and exhaust system, engine body, lubrication system, and cooling system values. It includes the standard values for new machines and service limit values for engine speed, air intake resistance, exhaust temperature, exhaust gas color, valve clearance, compression pressure, blow-by pressure, oil pressure, oil temperature, oil consumption, fan speed, and fan belt tension. A running-in standard and performance test standard is also included for both machine groups.

Testing and Adjusting

This chapter provides the testing and adjusting tools list, testing exhaust temperature, adjusting valve clearance, testing compression pressure, testing blow-by pressure, testing oil pressure, handling fuel system parts, releasing residual pressure in the fuel system, testing fuel pressure, reduced cylinder mode operation, no-injection cranking, testing leakage from the pressure limiter and return rate from injector, bleeding air from the fuel circuit, testing the fuel system for leakage, testing and adjusting alternator belt tension, handling the controller voltage circuit, and functions of the troubleshooting tool and check of failure code. Each procedure includes step-by-step instructions with photographs and torque values.

Troubleshooting

The troubleshooting chapter covers general information, points on troubleshooting, a failure code table, information in the troubleshooting table (E-mode), and method of using troubleshooting charts (S-mode). It includes mechanical system troubleshooting for S-1 through S-16 covering starting performance, engine not starting, engine not picking up smoothly, engine stopping during operations, engine not rotating smoothly, lack of output, black exhaust smoke, excessive oil consumption, contaminated oil, excessive fuel consumption, oil in coolant, oil pressure drop, oil level rise, overheating, abnormal noise, and excessive vibration. Electrical system troubleshooting covers E-1 through E-49 with failure codes, causes, and standard values in normal state.

Disassembly and Assembly

This chapter explains how to read the manual, provides a coating materials list, special tools list, general disassembly of engine, general assembly of engine, disassembly and assembly procedure for the fuel supply pump unit, and disassembly and assembly procedure for oil seal units. It includes tightening torques, quantities of oil and coolant, and weights of components. The general disassembly covers preparation work, setting the engine assembly, fan and turbocharger, alternator and fan pulley, wiring harness, oil cooler and adapter, engine controller and bracket, connector and thermostat, water pump, fuel filter, starting motor and oil level gauge guide, electrical intake air heater, high-pressure pipes, common rail and supply pump, air intake manifold, exhaust manifold, spill hose and injector, head cover, rocker arm, push rods and cylinder head mounting bolts, cylinder head assembly, oil pan, oil suction pipe, speed sensor and crankshaft pulley, gear case cover, idler gear, oil pump, camshaft, flywheel, flywheel housing, piston and connecting rod assembly, main cap, crankshaft, tappets, and cylinder block assembly.

Repair and Replacement of Parts

The S4D95LE-3 supplement includes repair and replacement procedures for the cylinder head section (grinding cylinder head mounting surface, replacing valve guide, grinding valve), cylinder block section (replacing camshaft bushing, replacing crankshaft gear, replacing cam gear, replacing flywheel ring gear, procedure for pressure test, cylinder liner, machining drawing for cylinder block bore, additional machining of cam journal, grinding crankshaft, replacing connecting rod small end bushing).

What This Manual Enables You to Do

With this Komatsu SAA4D95LE-5-A and S4D95LE-3 engine shop manual, you can confidently tackle everything from routine maintenance to complete engine overhauls. The manual provides the exact procedures, specifications, and torque values required to:

• Adjust valve clearance on both intake and exhaust valves
• Test compression pressure and blow-by pressure
• Test and adjust fuel pressure in the low-pressure circuit
• Test leakage from the pressure limiter and measure injector return rate
• Bleed air from the fuel circuit after fuel system work
• Test the fuel system for leakage using the color checker method
• Adjust alternator belt tension
• Read and clear failure codes using the troubleshooting tool
• Diagnose and repair mechanical and electrical system faults
• Disassemble and reassemble the engine, cylinder head, and all major components
• Replace valve guides, camshaft bushings, crankshaft gears, cam gears, and flywheel ring gears
• Grind the cylinder head mounting surface and crankshaft
• Perform pressure tests on the cylinder head
• Machine the cylinder block bore and install cylinder liners
• Replace connecting rod small end bushings

The manual includes detailed specifications for the high-pressure common rail fuel injection system, including the Bosch CP1H-OHW supply pump, CRI2.0 injectors, common rail pressure sensor, and IMV (Inlet Metering Valve). It also covers the TD04L turbocharger with waste gate valve, the electrical intake air heater, and the engine controller with its connectors and voltage circuits.

All procedures are supported by photographs, exploded diagrams, and cross-sectional illustrations that show exactly how components are assembled and how they should look when correctly installed. Maintenance standards, repair limits, and standard clearances are provided throughout, so you can determine whether a part is within specification or needs replacement. Tightening torques are given in both Nm and kgm, and the manual specifies where to apply molybdenum disulphide lubricant, engine oil, gasket sealant, and other coating materials.
