Re: Cat Marine C12.9

the overhaul critera for this engine is 228000 liters(60237gal) of fuel consumption or 4000 hours, according the manual.

if the enigne is run at low loads the interval will be increased.

Cat Marine C12.9

Hi, we have recently purchased 2 marine engines C12.9. There is a plate on the engines that basically state the usefu life is 1000hs. I can't believe this to be true and so an explanation as to what these 10 years or 1000hs would come in very handy.

Thanks a lot,
