01 Specification

Full engine specifications for the SAA6D170E-5 across all applicable machines, including rated output, max torque, no-load speeds, fuel consumption ratio, dry weight, dimensions, firing order, and total displacement. Engine performance curves and a weight table for major components are also included, making this section the starting point for any specification check or machine comparison.

10 Structure, Function and Maintenance Standard

This is the largest technical reference in the manual, covering the intake and exhaust system, EGR system, engine unit, cylinder head, cylinder block, cylinder liner, main moving parts, crankshaft, camshaft, connecting rod, piston assembly, flywheel housing, vibration damper, gear train, timing gear, valve system, lubrication system, cooling system, fuel system, and electrical equipment. Each section explains how the component works and provides the maintenance standard values used during inspection and repair.

20 Standard Value Table

Standard service values for testing, adjusting, and troubleshooting, covering high idle speed, low idle speed, air boost pressure, exhaust temperature, compression pressure, blow-by pressure, oil pressure, oil temperature, and more. Separate tables are provided for D375A-5, PC1250-8/PC1250-7, WA600-6, and HD465-7/HD605-7 machines. Running-in standards and performance test standards are also included.

30 Testing and Adjusting

Procedures and tool lists for testing air boost pressure, exhaust temperature, compression pressure, blow-by pressure, and oil pressure. Includes valve clearance adjustment, fuel pressure testing, reduced cylinder mode operation, no-injection cranking, pressure limiter leakage testing, injector return rate testing, fuel circuit bleeding, and fuel system leakage inspection.

40 Troubleshooting

Mechanical system troubleshooting (S-mode) with detailed charts for poor starting, engine not starting, lack of power, black exhaust smoke, oil consumption, overheating, abnormal noise, and vibration. Electrical system troubleshooting (E-mode) with error code and failure code tables covering ECM failures, sensor errors, injector circuit faults, rail pressure errors, EGR valve servo errors, and bypass valve errors.

50 Disassembly and Assembly

General disassembly and assembly procedures for the SAA6D170E-5 engine, including removal and installation of the fuel supply pump unit and replacement of the rear and front oil seals on an engine mounted in the machine. Coating materials, special tools, and tightening torques are listed throughout.

What This Komatsu 170E-5 Shop Manual Covers

The Komatsu 170E-5 Series Engine Shop Manual covers the SAA6D170E-5 engine in full workshop detail, from the 170 mm bore and 170 mm stroke to the common rail fuel injection system and cooled EGR circuit. Whether you are adjusting valve clearance, testing compression pressure, tracing a rail pressure fault code, or removing the cylinder head, this manual provides the factory procedures, wear limits, and tightening torques for the job.

Because the engine is used across bulldozers, excavators, wheel loaders, and dump trucks, the manual includes model-specific standard value tables for each machine. That means you get the correct idle speeds, boost pressures, and exhaust temperatures for the D375A-5, PC1250-8, WA600-6, HD465-7, and HD605-7 rather than a single generic specification.

Who This Manual Is For

This Komatsu engine service manual is written for diesel mechanics, fleet maintenance shops, and heavy equipment technicians who need to diagnose, repair, or overhaul the SAA6D170E-5 engine. It is also useful for equipment owners who want to understand the correct service procedures and specifications before authorizing repairs or performing maintenance themselves.

The troubleshooting sections are particularly valuable when the engine is derated or a fault code appears on the machine monitor. The error code and failure code tables let you match an INSITE code or machine failure code to the affected circuit, then follow the step-by-step checks for wiring, sensors, and actuators.
