Your application will involve very low revs for a lot of the time and I think this should squeeze a few more hours. In fairness, he was suggesting 1500hrs as the time they started to have major failures.
Surely that incorrect? 1500 hours? thats equivalent to 45,000 miles in a car! Most diesels I have worked on wouldn't be considered fully run in at 1000 hours. our hire boats used to clock up over 1000 hours a year, and my mates tractor clocked up 12000 hours in 4 years,
The generator outside iceland in Monmouth ran for a year continuously,
thats 8000 odd hours!
in my plant experience we found heavily used plant engines generally got tired at 10-20000 hours, and generally got run out of oil by hirers, so were murdered rather than popping their clogs from naturel causes
wern't the lister generators sold to trinity house specced to run 52,000 hrs(six years) continuous ?
obviously engine load makes a big difference, and boat engines tend to be heavily loaded, but conversley in a vehicle application its the stop start that wears them out, marine engines tend to be more constant speed use and stopped/started less?
