I got a 725c haul truck using hydraulic oil and I can’t find leak the engine is 2 to 3 gallons over fill any ideal how it is getting in there all pumps are mounted on trans nothing on engine I am seeing.
I see this has not received any replies, might help to include a S/N as there are at least 6 different S/N prefixes for a 725C and I'm not familiar with them to make a wild guess as to what the problem could be. Also how about a rough idea of how fast the oil seems to be transfering from hydraulics to engine, is it in one eight hour shift or 100 hours running? Might make a difference.
