18VPC2.6

Common issues

• Excessive cylinder liner wear due to poor fuel quality or inadequate maintenance
• Charge air leakage causing reduced engine performance and increased fuel consumption
• Fuel pump failure resulting in engine shutdown or reduced power output
• Crankshaft bearing wear due to misalignment or inadequate lubrication
• Turbocharger fouling or failure leading to reduced engine efficiency
• Exhaust valve leakage or damage causing reduced engine performance and increased emissions
• Piston ring wear or breakage resulting in reduced engine efficiency and increased oil consumption

Inspection checklist

• Cylinder head and valve condition
• Piston and ring condition
• Crankshaft and bearing condition
• Fuel pump and injector condition
• Turbocharger condition and performance
• Charge air system condition and performance
• Lubrication system condition and performance
• Exhaust system condition and performance
• Engine mounts and alignment

Service intervals

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

• Fuel injectors
• Cylinder liners
• Piston rings
• Crankshaft bearings
• Turbocharger components
• Exhaust valves
• Cylinder head gaskets

Safety

• High-pressure fuel system leaks or ruptures
• Scalding from hot engine components or pipes
• Electrical shock from faulty wiring or components
• Crushing or entanglement hazards from moving engine parts

Class survey

Class surveyor typically checks engine performance, fuel consumption, and emissions, as well as inspecting critical components such as cylinder heads, pistons, and crankshaft bearings for signs of wear or damage.

Estimated lifetime: 30000-50000 hours
