KOMATSU D61 WORKSHOP MANUAL INFORMATION
The Komatsu D61 Workshop Manual provides detailed technical information for maintaining, diagnosing and repairing D61EX-15 and D61PX-15 crawler bulldozers.
Crawler bulldozers operate in demanding construction and earthmoving environments where major components are subjected to heavy loads, vibration, dust, dirt, mud and long operating periods.
Accurate technical information is therefore important when carrying out maintenance, investigating faults or undertaking major repairs.
The manual can be consulted before dismantling components to understand the relevant machine system and identify the appropriate workshop procedure. During repairs it provides a technical reference for inspection, testing and adjustment. It can then be used during reassembly and final checks before the machine is returned to service.
SERVICE AND MAINTENANCE
Regular servicing is essential for maintaining the reliability and working life of a Komatsu D61 bulldozer.
This workshop manual provides a useful technical reference when carrying out planned servicing, inspections and investigation of abnormal machine operation.
For machines with high operating hours or an incomplete previous service history, correct workshop information can be particularly valuable when assessing machine condition.
Regular inspection can help identify developing wear and faults before they lead to more serious component failure and expensive machine downtime.
SPECIFICATIONS AND TECHNICAL INFORMATION
Correct specifications are important when checking component condition and diagnosing machine problems.
Measurements and operating values obtained from the machine can be compared with the appropriate workshop information.
This can help determine whether a component or system is operating correctly or whether further adjustment, inspection or repair is required.
TROUBLESHOOTING AND FAULT DIAGNOSIS
Fault diagnosis can be one of the most difficult and time-consuming parts of heavy equipment repair.
Mechanical, hydraulic and electrical systems operate together, so a symptom appearing in one area may sometimes be caused by a problem elsewhere in the machine.
The Komatsu D61 Workshop Manual provides technical information that can assist with a systematic approach to troubleshooting.
Workshop specifications, testing information and diagnostic procedures can help mechanics investigate the actual cause of a problem before replacing components.
This can reduce unnecessary parts replacement, repair costs and machine downtime.
TESTING AND ADJUSTMENT
Correct testing and adjustment are important during fault diagnosis and following repair work.
Workshop procedures and specifications can be used to determine whether machine systems are operating within the required values.
If test results are outside specification, further investigation can be carried out before expensive components are removed or replaced.
After repairs have been completed, the relevant information can also be used when carrying out final adjustments and checks.
REPAIR AND OVERHAUL INFORMATION
With 987 pages, this is a substantial workshop manual suitable for normal service work as well as extensive component repair and overhaul.
Major repairs may require complete assemblies to be removed and dismantled. Components can then be inspected for wear or damage before repair, replacement, adjustment and correct reassembly.
Having the appropriate workshop information available throughout the repair provides a consistent technical reference.
Workshop information may assist with areas including:
• General machine information
• Engine and associated systems
• Cooling system
• Fuel system
• Power train
• Transmission and drivetrain
• Steering and braking
• Final drives
• Undercarriage
• Hydraulic systems
• Work equipment
• Blade equipment
• Electrical systems
• Controls and instrumentation
• Testing and adjustment
• Troubleshooting
• Disassembly and assembly
• Maintenance standards
ENGINE AND RELATED SYSTEMS
Reliable engine operation is essential to overall bulldozer performance.
Problems involving fuel delivery, cooling or associated engine systems can cause poor starting, reduced performance, overheating or other operating difficulties.
The workshop manual provides technical information to assist with applicable engine inspection, testing, servicing and repair procedures.
POWER TRAIN AND TRANSMISSION
The power train transfers engine power through the bulldozer and is critical to dependable machine operation.
Wear, incorrect adjustment or component failure can result in reduced performance, abnormal operation or loss of drive.
The Komatsu D61 Workshop Manual provides a useful technical reference when investigating power train and transmission problems.
Accurate workshop information is particularly valuable during major dismantling, repair and reassembly work.
HYDRAULIC SYSTEM
The hydraulic system operates important bulldozer and work equipment functions.
Weak, slow or irregular hydraulic operation may be caused by component wear, contamination, incorrect adjustment or another fault within the system.
Correct technical information can assist mechanics with systematic inspection, testing and diagnosis before expensive hydraulic components are removed or replaced.
The manual can also provide useful information for adjustment, repair and reassembly procedures where covered by the original publication.
UNDERCARRIAGE AND FINAL DRIVES
Crawler bulldozer undercarriage components operate under severe working conditions and are subjected to continuous loads and wear.
Tracks, rollers, idlers, sprockets, final drives and associated components require regular inspection and maintenance.
The workshop manual provides useful technical information when assessing component condition, investigating abnormal wear and carrying out repairs.
WORK EQUIPMENT
The blade and associated work equipment operate under heavy loads throughout normal bulldozer operation.
Correct inspection, servicing and repair are important for dependable machine performance.
The manual provides technical information for work equipment systems and components covered by the original workshop publication.
ELECTRICAL SYSTEM
Electrical faults can be difficult to diagnose without suitable technical information.
Problems involving wiring, starting, charging, controls or instrumentation can cause unreliable or incorrect machine operation.
The workshop manual provides a useful reference when investigating electrical problems and carrying out applicable testing and repair procedures.
DISASSEMBLY AND ASSEMBLY
Major workshop repairs frequently require complete components or assemblies to be removed and dismantled.
Correct procedures are important to avoid unnecessary damage and help ensure that repaired assemblies are rebuilt correctly.
The manual provides technical information that can assist with applicable removal, disassembly, inspection, repair, assembly and installation procedures.
KOMATSU D61EX-15
