Komatsu D85EX-15R & D85PX-15R Bulldozer Shop Manual SEN02947-03 – PDF Repair Guide

Description

Komatsu D85EX-15R & D85PX-15R Bulldozer Shop Manual – SEN02947-03

This is the complete Komatsu shop manual for the D85EX-15R and D85PX-15R bulldozers, issued under Form No. SEN02947-03. It is the full workshop reference used for servicing, repairing, testing, adjusting, disassembling and troubleshooting these machines, and it is written for the technician who needs exact procedures, standard values and component-level detail rather than a general overview.

The manual applies to D85EX-15R machines from serial number 20001 and up, and D85PX-15R machines from serial number 20001 and up. It covers the Komatsu SAA6D125E-5 engine along with the complete chassis – power train, HSS steering and brake system, hydraulic system, work equipment, undercarriage, cab and electrical system.

Chapters Covered

The shop manual is filed by section and Form No., exactly as Komatsu issues it. The contents break down as follows:

• 00 Index and Foreword – composition of the shop manual, table of contents, safety notice, how to read the shop manual, explanation of terms for maintenance standards, handling of electric equipment and hydraulic components, handling of engine connectors, how to read electric wire codes, precautions during operation, push-pull coupler handling, standard tightening torque table, conversion tables.
• 01 Specification – specification dimensions, machine specifications, weight table, table of fuel, coolant and lubricants.
• 10 Structure, Function and Maintenance Standard
  • Engine mount and cooling system (cooling fan pump, cooling fan motor)
  • Power train Part 1 (HSS system, transmission control, steering and brake control, damper and universal joint, torque converter and PTO, transmission, transmission clutch ECMV, main relief valve and torque converter relief valve, lubrication relief valve)
  • Power train Part 2 (bevel gear shaft, HSS, brake, brake valve, final drive)
  • Undercarriage and frame (main frame, suspension, track frame, idler cushion, idler, track roller, carrier roller, sprocket, track shoe)
  • Hydraulic system Parts 1-3 (work equipment and PPC control piping, hydraulic tank and filter, scavenging pump, power train and steering lubrication pump, HSS pump and motor, control valve, self pressure reducing valve, oil cooler bypass valve, PPC valve, electric steering lever, quick drop valve, PPC lock valve, accumulator)
  • Work equipment (cylinder stay, blade, cutting edge and end bit, ripper, hydraulic cylinder, piston valve)
  • Cab and its attachments (cab mount, cab, air conditioner)
  • Electrical system (monitor system, monitor panel, engine control, CRI engine control system, Palm Command Control System, KOMTRAX system, sensors)
• 20 Standard Value Table – standard service value table for engine and for chassis.
• 30 Testing and Adjusting – tools, measuring engine speed, boost pressure, exhaust temperature and gas color, valve clearance, compression pressure, blow-by pressure, engine oil pressure, fuel system handling, fuel pressure, return and leak testing, air bleeding, belt tension, fuel control dial and decelerator pedal, power train oil pressure, transmission speed sensor, brake performance, brake pedal and parking brake lever, idler clearance, sprocket wear, track shoe tension, work equipment and HSS oil pressure, control circuit basic pressure, PPC valve output pressure and play, hydraulic drift diagnostics, cylinder internal leakage, air bleeding, fan motor speed and fan pump circuit pressure, blade adjustment, operator cab testing and adjusting, monitor panel (EMMS) special functions, controller replacement adjustment, diode inspection, Pm Clinic service, KOMTRAX terminal setup.
• 40 Troubleshooting – failure code table and fuse locations, general information on troubleshooting, connector pin number connection tables, troubleshooting by failure code (Parts 1-4), troubleshooting of electrical system (E-mode, E-1 through E-31), troubleshooting of hydraulic and mechanical system (H-mode, H-1 through H-19), troubleshooting of engine (S-mode, S-1 through S-17).
• 50 Disassembly and Assembly – general information, engine and cooling system Parts 1-2, power train Parts 1-2, undercarriage and frame Parts 1-2, hydraulic system, work equipment, cab and its attachments, electrical system.
• 90 Diagrams and Drawings – hydraulic diagrams and drawings (power train hydraulic circuit diagram, hydraulic circuit diagram), electrical diagrams and drawings (electrical circuit diagrams 1/7 through 7/7, cab electrical circuit diagram, air conditioner electrical circuit diagram, connector list and stereogram).

What ties this all together is that the manual is structured the way a technician actually works on a machine: specifications first, then the structure and function of every assembly, then the standard values you measure against, then the procedures to test and adjust, then how to diagnose faults by symptom or failure code, then how to remove, disassemble, assemble and reinstall each component. Every system on the D85EX-15R and D85PX-15R is treated at that level.

What This Shop Manual Enables You To Do

With the Komatsu D85EX-15R & D85PX-15R Shop Manual SEN02947-03 in hand, you have the reference needed for a wide range of jobs on these bulldozers. This includes engine service on the SAA6D125E-5 – valve clearance adjustment, compression and blow-by pressure testing, engine oil pressure checks, injector and supply pump work, cylinder head removal and installation. It covers the torque converter, TORQFLOW transmission, PTO and damper, along with the HSS (Hydrostatic Steering System) pump, motor, brake valve and final drive. It gives the procedures for the hydraulic system, including the control valve, PPC valve, self pressure reducing valve, HSS pump and motor and hydraulic cylinders, plus the fan drive circuit.

The undercarriage is fully covered as well – track frame, idler and idler cushion, recoil spring, track roller, carrier roller, sprocket and track shoe, with the standard clearances, wear limits and adjustment procedures you need to keep the machine tracking correctly.

Troubleshooting is one of the strongest parts of this shop manual. The failure code table and the E-mode (electrical), H-mode (hydraulic and mechanical) and S-mode (engine) troubleshooting sections give you a defined path from a symptom or a code on the monitor panel down to the failed component, with standard values and normal-state readings at each step so you can confirm a fault rather than guess at it.

Because the manual gives you the correct procedures, tightening torques, standard clearances and diagnostic values, you work to the same reference the machine was built to. That means fewer repeat repairs, less risk of damaging components through improper assembly or over-torquing, and faster fault-finding on systems like the HSS steering, ECMV-controlled transmission and electronically controlled engine.
