So, checked out my machine today. It's pretty much dismantled. They checked the fuel pump to make sure it had the right barrels installed for that fuel pump, and they were correct.They think that the machine is not cooling correctly. They took the radiator out and found the cooling tubes on the bottom, about75% of them were plugged with what looked like to me, seeds from a tree,an olive tree,or seeds from some kind of plant.Next,they are sending it off to MPLS. to get it checked to see if it is still usable .They have the shop manager working on it. He said that he has worked on several 3306 engines before and would like to see this one out of bay#4 back to work again!He is quite puzzled by this machine. One other thing, I told him how the machine was laboring as I was going across the field, before I even put it under load. He is going to check the transmission filter.,might be plugged, causing engine to overheat.They did replace the water heat gauge, the original gauge, he said was not working when I first brought it in.
