It is suitable for Komatsu 95 Series engines installed in construction machinery, agricultural equipment, industrial machines and other Komatsu-powered applications.
Engine Series Covered
• Komatsu 95 Series diesel engines
Different versions of the Komatsu 95 engine may have variations in equipment, components and technical specifications. Always check the complete engine model, serial information and identification plate fitted to your equipment before beginning servicing or repair work.
Engine Construction and Operation
The Komatsu 95 Engine Workshop Manual explains the construction, arrangement and operating principles of the main engine systems. Understanding how these systems work together provides a reliable foundation for maintenance, fault diagnosis and major repairs.
Coverage relates to the main engine assembly, cylinder block, cylinder head, pistons, piston rings, connecting rods, crankshaft, bearings, valve-operating components and associated internal parts. Detailed technical illustrations and workshop instructions assist with component identification and correct assembly.
Routine Maintenance and Servicing
Regular maintenance is essential for dependable starting, efficient performance and a long engine service life. This manual contains useful information for scheduled maintenance, general inspection and routine workshop servicing of Komatsu 95 Series engines.
Maintenance procedures may include lubrication checks, cooling-system inspection, fuel-system servicing, filter maintenance and engine adjustments. Following the correct service procedures can help identify wear, leakage and incorrect settings before they result in a serious mechanical failure.
Fuel and Injection System
The diesel fuel system must deliver clean fuel in the correct quantity and at the proper time. This workshop manual provides information for inspecting, testing, servicing and adjusting fuel-system components fitted to the Komatsu 95 engine series.
The fuel-system information can assist when investigating difficult starting, loss of power, uneven running, excessive fuel consumption or abnormal exhaust smoke. Injection equipment should be handled carefully and serviced according to the correct procedures and specifications.
Air Intake and Exhaust Systems
Correct airflow is necessary for efficient combustion and dependable engine operation. The manual provides technical information for checking the air-intake and exhaust systems.
This guidance can assist with identifying restrictions, leakage or component faults that may contribute to poor performance, increased fuel consumption and excessive exhaust smoke. Where fitted, forced-induction components should be inspected and serviced using the appropriate workshop procedures.
Cooling System
The engine cooling system controls operating temperature and protects components against overheating. The manual includes information useful for inspecting, testing and repairing cooling-system components.
Depending on the engine version, coverage may include the water pump, thermostat, coolant passages and related parts. The procedures can assist when diagnosing overheating, coolant leakage, slow engine warm-up and abnormal operating temperatures.
Lubrication System
Correct lubrication protects bearings, cylinder surfaces and other moving components against friction and premature wear. The manual contains technical guidance relating to the oil pump, filters, lubrication passages and associated components.
This information can help diagnose low lubricating-oil pressure, excessive oil consumption, external leakage and signs of inadequate lubrication. Using the correct oil and following recommended servicing procedures are essential for reliable engine operation.
Engine Dismantling
Detailed dismantling procedures help technicians remove components in the correct sequence. Following the stated workshop instructions reduces the possibility of damaging parts that may be suitable for reuse.
The manual supports both individual component repairs and complete engine overhauls. It provides a structured reference for removing, dismantling, cleaning and organising engine components before inspection.
Component Inspection and Measurement
Accurate inspection is essential during any major engine repair. Parts must be examined for cracking, distortion, scoring, excessive clearance and general wear before being approved for continued use.
The manual may provide dimensions, clearances and service limits for cylinder bores, pistons, piston rings, crankshaft journals, bearings, valves and valve guides. These measurements help determine whether a component remains serviceable, requires specialist machining or must be replaced.
Engine Reassembly and Adjustment
Correct assembly is critical to engine reliability following a repair or overhaul. The Komatsu 95 Engine Workshop Manual provides guidance for installing inspected or replacement components in the proper order.
Where applicable, the manual includes tightening information, adjustment values, assembly requirements and final checks. Following the stated procedures helps prevent incorrect clearances, loose components and avoidable engine damage.
Engine Fault Diagnosis
The manual provides a detailed technical reference for methodically investigating common diesel-engine problems, including:
• Engine fails to start
• Difficult starting when hot or cold
• Reduced engine power
• Poor performance under load
• Uneven or unstable operation
• Excessive exhaust smoke
• Engine overheating
• Abnormal mechanical noise
• Low engine-oil pressure
• Excessive lubricant consumption
• Fuel, oil or coolant leakage
• Unusual vibration or engine response
Using the correct workshop procedures can reduce diagnosis time and help avoid unnecessary replacement of serviceable components.
Technical Specifications
Accurate specifications are vital when completing adjustments, repairs and complete engine rebuilds. Depending on the engine version and procedure, the manual may provide component dimensions, operating clearances, inspection limits, adjustment values and tightening information.
Always use the specifications for the exact Komatsu 95 Series engine model being repaired. Technical figures from another engine version should not be used unless the manual confirms that they are identical.
