01 Specification

The Specification chapter provides the technical data for the D155AX-6, including dimension drawings, machine specifications, a weight table, and the table of fuel, coolant and lubricants. This section gives you the baseline data needed to understand the machine’s capacities and operating limits before any service work begins.

10 Structure, Function and Maintenance Standard

This extensive chapter breaks down the structure and function of every major system on the D155AX-6, along with the maintenance standard values used to judge wear and serviceability. It covers the engine and cooling system, power train (Parts 1 and 2), undercarriage and frame, hydraulic system, work equipment, cab and attachments, and the complete electrical system. Each subsystem is explained with detailed illustrations, cutaway views, and maintenance criteria, making this chapter an essential reference for understanding how the machine is built and how to evaluate component condition.

20 Standard Value Table

The Standard Value Table provides the standard service values for the engine and the machine, including measurement conditions, standard values for new machines, and service limit values. This is the go-to reference for determining whether a component is within specification or requires repair or replacement.

30 Testing and Adjusting

The Testing and Adjusting chapter is divided into four parts and covers the tools, instruments, and procedures required to test and adjust the D155AX-6. It includes measuring engine speed, intake air pressure, exhaust temperature, exhaust gas colour, compression pressure, blow-by pressure, and engine oil pressure, as well as fuel system pressure testing and bleeding. It also covers power train oil pressure measurement, brake performance testing, transmission output shaft speed sensor adjustment, track shoe tension, work equipment and HSS oil pressure, control circuit basic pressure, and many other critical adjustments. This section is indispensable for accurate diagnostics and proper machine setup.

40 Troubleshooting

The Troubleshooting chapter is organised by failure and error codes and is divided into multiple parts. It begins with general troubleshooting information, connector pin numbers, and a T-boxes and T-adapters table. It then provides detailed troubleshooting procedures for a vast range of failure codes covering the transmission clutch, forward and reverse clutches, speed clutches, lock-up clutch, brakes, engine sensors, fuel system, EGR system, CAN communication, and much more. Each failure code entry includes the contents of the trouble, the action taken by the controller, the problem that appears on the machine, related information, and possible causes with standard values in the normal state. This chapter is the primary resource for diagnosing and resolving electrical and mechanical faults on the D155AX-6.

50 Disassembly and Assembly

The Disassembly and Assembly chapter provides the special tools and step-by-step procedures for removing, installing, disassembling, and assembling the major components of the D155AX-6. It covers the engine and cooling system, power train (Parts 1, 2, and 3), undercarriage and frame, hydraulic system, work equipment, cab and attachments, and the electrical system. Each procedure includes tightening torques, coating material quantities, oil and coolant capacities, and the weight of components for safe handling. This is the definitive guide for anyone performing a rebuild or major repair.

90 Diagrams and Drawings

The Diagrams and Drawings chapter contains the power train hydraulic circuit diagram, hydraulic circuit diagrams (Parts 1 and 2), the electrical circuit diagram, the electrical circuit diagram for inside the cab, and the connectors table and arrangement drawing. These diagrams are essential for understanding the hydraulic and electrical systems and for tracing circuits during troubleshooting.
