Komatsu D41E-6 & D41P-6 Dozer Shop Manual SEBM007009 – PDF Service & Repair Guide

Description

Komatsu D41E-6 & D41P-6 Shop Manual — Complete PDF Service & Repair Guide

This is the complete Komatsu D41E-6 and D41P-6 Shop Manual, document number SEBM007009, covering both serial number ranges: B20001 – B40000 and 50001 and up. At 677 pages, it is the full workshop reference for these dozers — from specifications and structure/function through testing and adjusting, complete disassembly and assembly procedures, and the maintenance standard values used to judge wear and decide on replacement.

The manual is written for the technician working on the machine. It explains how each system is built and how it operates, then gives the procedures, pressures, clearances, torque figures and wear limits needed to test, adjust, tear down and rebuild it correctly. Engine details are covered by the separately referenced 102 Series Engine Shop Manual for the S6D102-1 engine; this volume focuses on the machine — power train, steering and brakes, undercarriage, hydraulics, work equipment, electrical and monitor systems.

01 GENERAL

Specifications for both the D41E-6 and D41P-6, including performance figures, dimensions, operating weights, ground pressure, speed ranges, gradeability and stability. The weight table lists component and assembly weights for lifting and transport planning. A table of fuel, coolant and lubricants gives capacities and the correct fluid for each ambient temperature band.

10 STRUCTURE AND FUNCTION

The largest chapter, explaining how the machine is built and how each system works. It covers the radiator and oil cooler, engine control, the full power train system, hydraulic piping drawings, damper and universal joint, transmission (planetary gear sets with disc clutches giving three forward and three reverse speeds), the transmission control valve with its modulating and inching valves, steering/brake/inching control, bevel gear shaft, steering clutch and steering brake, steering PPC valve, steering piston, priority valve, brake valve, power train oil filter, final drive, frame assembly, track frame, recoil spring, and work equipment hydraulics including the CLSS (Closed center Load Sensing System). Air conditioner layout, electrical circuit diagrams, the engine control safety mechanism, machine monitor system and its sensors are also described.

20 TESTING AND ADJUSTING

Standard value tables for engine, chassis and machine monitor, followed by step-by-step procedures: valve clearance adjustment, blow-by measurement, fuel injection timing, exhaust colour, engine oil pressure, engine speed, fuel control linkage, decelerator pedal linkage, engine stop solenoid, steering/directional/gear shift lever adjustment, main brake and parking brake testing, brake and clutch lining wear measurement, brake pedal, inching pedal and parking brake linkage adjustment, work equipment control and safety lever linkage, power train oil pressure measurement, work equipment circuit pressure, track shoe tension, internal cylinder leakage, bleeding air from the hydraulic circuit, releasing the parking brake, and operator’s cab checks. The troubleshooting section is divided into engine (S mode), electrical (E mode), hydraulic/mechanical (H mode) and machine monitor (M mode), with connector tables, T-adapter references and detailed flowcharts.

30 DISASSEMBLY AND ASSEMBLY

Removal, installation, disassembly and assembly procedures for the major components and assemblies: radiator and oil cooler, hydraulic cooler, main control valve, main relief valve, steering PPC valve, blade angle/lift/tilt cylinders, hydraulic cylinder overhaul, work equipment, hydraulic tank, ROPS roof and guard, canopy, operator’s cab, cab glass (stuck glass), floor frame, air conditioner compressor and condenser, monitor, DT and HD connector pins, wiring harness repair, fuel injection pump, engine hood, cylinder head, fuel tank, engine assembly, radiator guard, transmission, steering case, brake control valve, transmission shift valve, transmission pressure valve, steering piston, parking brake cylinder, final drive, idler, recoil spring, track roller, carrier roller, track shoe, one-link field repair, and the hydraulic pump. Includes the special tool list and sketches of special tools.

40 MAINTENANCE STANDARD

The judgement chapter — wear limits, standard clearances, tolerances and repair limits for damper and universal joint, hydraulic and power train pump, transmission, transmission control valve, bevel gear shaft, steering clutch and steering brake, steering PPC valve, steering piston, priority valve, brake valve, parking brake cylinder, final drive, track frame and recoil spring, idler, track roller, carrier roller, track shoe, main control valve, work equipment cylinder, work equipment, and cutting edge and end bit. Use these values to decide whether a part can be reused, adjusted, rebuilt or must be replaced.

90 OTHERS

Power train hydraulic system diagram, power train hydraulic circuit diagram, work equipment hydraulic system diagram, work equipment hydraulic circuit diagram, actual electric wiring diagram, and the complete electrical circuit diagrams for machines with cab and without cab.

What This Komatsu D41E-6 D41P-6 Shop Manual Lets You Do

This is not a generic overview. It is the working document for diagnosing and repairing these dozers — the same categories of information a workshop relies on when a machine comes in with a steering complaint, a transmission that shifts harshly, a brake that drags, a final drive noise, a hydraulic drift problem, or a monitor panel that flashes a warning. You get the pressures to test against, the linkage dimensions to set, the torque figures to tighten to, the shim and clearance values to check, and the wear limits that tell you when a component is finished.

The troubleshooting flowcharts are organised by symptom and system, so you can follow a fault from the operator’s report through electrical, hydraulic or mechanical checks to the cause and the remedy. The structure and function chapter gives the background to understand why a circuit behaves as it does, which makes fault-finding faster and more certain. The disassembly and assembly chapter gives the order of operations, the tools, the tightening torques and the precautions — so a rebuild goes back together correctly.

For anyone maintaining a D41E-6 or D41P-6 across either serial range, this manual supports the full range of work: routine adjustment and testing, component repair, major assembly overhaul, and maintenance-standard judgement. It is the reference that keeps procedures and specifications correct rather than approximate.
