The troubleshooting section helps identify common diesel engine faults including difficult starting, failure to start, reduced power, irregular running, excessive fuel consumption, overheating, low oil pressure and abnormal engine noise.
Information is also included for diagnosing black, white and blue exhaust smoke. These symptoms may result from fuel-system faults, incorrect injection timing, worn internal components, cooling problems or lubrication issues.
The fuel-system section covers the fuel supply circuit, injection pump, injectors, governor components and injection timing. It provides inspection and adjustment procedures to help correct poor starting, uneven running, loss of power and excessive smoke.
Turbocharger procedures cover inspection, servicing and fault diagnosis of the forced-induction system. Correct turbocharger operation is essential for maintaining engine performance, fuel efficiency and acceptable exhaust emissions.
Cooling-system information includes the water pump, thermostat, coolant passages and related components. Proper cooling-system maintenance helps prevent overheating, cylinder-head damage and premature engine wear.
The lubrication section covers the oil pump, filters, oil passages and oil-pressure checks. These procedures help identify low oil pressure, poor oil circulation and excessive internal engine wear.
Cylinder-head repair information covers removal, dismantling, inspection and installation. Procedures are included for checking valves, valve seats, guides, springs, rocker components and cylinder-head condition.
The lower-engine section covers the cylinder block, liners, pistons, piston rings, connecting rods, crankshaft, bearings, camshaft and timing gears. Standard measurements, service limits and repair limits help determine whether parts can be reused or require replacement.
Detailed engine dismantling instructions explain the correct sequence for removing major components. Inspection procedures help identify wear, cracking, distortion and other damage before reassembly.
Engine reassembly procedures include tightening sequences, torque settings, clearances and adjustment information. Following the correct specifications is essential for reliable engine performance and a long service life.
This manual is a valuable workshop reference for routine servicing, fault diagnosis, component replacement and complete engine overhaul. It can help reduce unnecessary dismantling and ensure repairs are completed according to Komatsu service standards.
