Common failures & inspection points
Inspect piston wear and scratches on piston rings – for VMC models inspect the critical sealing surface
Inspect crankshaft for wear, cracks and bearing play – particularly in high-cylinder versions such as VMC 450XL
Inspect intake valves and discharge valves for wear, varnishing and contamination – at pressure up to 36 bar critical
Inspect oil separator and oil cooler for varnishing and throttling – continuous maintenance for VSS/VSMC single-screw models
Inspect Parallex slide system (single-screw models) for wear and positioning accuracy for optimum efficiency
Inspect bearings and bearing tolerances – particularly critical for VSS models with their 5/15 year warranty
Inspect flange seals, pipe connections and joints for leakage and corrosion
Inspect coolant circulation and thermal condition – for ammonia (R-717) and halocarbon systems assessed separately
