Common failures & inspection points

Cylinder liner scuffing: Local welding and wear between piston ring and liner inner surface caused by inadequate lubrication or oil film breakdown

Visual inspection of liner for scratches, micro-welding and discoloration; check local surface roughness; hone liner or replace if necessary

Piston crown and ring groove wear: Surface stress, wear and cracks in piston crown and ring grooves require thickness measurements

Use thickness gauge (e.g. Fischer Dualscope MP0); compare with reference values from OM; inspect piston crown for thermal discoloration, cracks and deposits

Fuel pressure anomalies and groove leakage: Excessive/insufficient pressure in common rail system and fuel leakage from injection lines

Check fuel pressure during operation (reference value at R1); monitor fuel return for leaks; observe inspection lines at injectors for leaks

Exhaust temperature irregularities with elevated gas concentration in piston underside: Asymmetrical or unexpected exhaust temperatures downstream of individual cyl

Perform continuous exhaust temperature monitoring per cylinder; initiate cylinder head inspections at temperature differences >30°C; check gas concentration in piston

Servo oil system leakage and FLV/fuel line tightness issues: pressure loss in servo hydraulic system and fuel leak at Fuel Line Valves

Monitor servo oil pressure and flow; visually inspect all fuel lines and valve connections and under pressure; monitor sight glasses
