Description

Komatsu D155AX-8 Bulldozer Shop Manual — SEN06497-03

This is the complete Komatsu D155AX-8 bulldozer shop manual, document number SEN06497-03, covering machines from serial number 100001 and up. It is a full workshop-level service publication — not a condensed owner’s guide — written for technicians who need the manufacturer’s own procedures, specifications, and diagnostic logic for every major system on the machine.

The manual covers the SAA6D140E-7 diesel engine and the complete machine: torque converter and PTO, transmission, HSS steering unit, brakes, final drives, bevel gear shaft, hydraulic system with CLSS, work equipment, undercarriage and frame, ROPS cab, and the Tier 4 Final aftertreatment package including KDPF and the urea SCR system. It also contains the electrical and hydraulic circuit diagrams, a full standard value table, and the maintenance standard chapter used for wear limits and reuse decisions.

As a whole, this shop manual gives a technician the full picture of how the D155AX-8 is built, how each system behaves, what the correct pressures, clearances and torque values are, how to test and adjust components, how to interpret failure codes and symptoms, and how to disassemble and reassemble the machine correctly. The standard value and maintenance standard chapters are what turn guesswork into measurable service decisions.

What This Manual Enables You To Do

With this Komatsu D155AX-8 shop manual, you can carry out scheduled maintenance, diagnose faults by failure code or by symptom, test hydraulic and power train pressures, adjust engine and transmission settings, remove and install major assemblies, and rebuild components to the correct specifications. It supports everything from routine service through to major component overhaul.

The value is in the exactness: correct tightening torques, correct oil and coolant capacities, correct standard clearances and repair limits, correct test procedures, and the correct sequence for disassembly and reassembly. Working from the manufacturer’s own numbers is what prevents repeat failures, damaged components, and unnecessary downtime.
