Inspection

Inspector Detail

Common issues

  • Fuel system leaks and contamination due to Common Rail system complexity
  • Cylinder liner and piston ring wear due to high compression ratio and MGO/HFO fuel types
  • Turbocharger fouling and failure from inadequate maintenance and high exhaust gas temperatures
  • Lube oil system contamination from fuel or coolant leaks
  • Excessive vibration from misaligned or loose engine mounts
  • Cooling system corrosion and leaks from inadequate water treatment
  • Starting air system leaks and valve failures

Inspection checklist

  • Check fuel system for leaks and contamination
  • Inspect cylinder liners and piston rings for wear
  • Verify turbocharger condition and performance
  • Check lube oil system for contamination and condition
  • Inspect engine mounts and alignment
  • Check cooling system for corrosion and leaks
  • Verify starting air system condition and performance
  • Check exhaust gas temperatures and emissions
  • Inspect crankcase and camshaft condition

Free of charge — send us your request for MAN Generator (PrimeServ) equipment. Our team checks it and replies by e-mail.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
