This is the belly of a Cat 277 that I brokered about a week ago. This baby is dry! No signs of any leaks, maybe it is just a tub with no where for the oil to leak out. I like that it is so straight and that it is so high as well, lots of ground clearance. From this vantage point it is pretty easy to see the inside groups of rollers, the amount of chunking in the rubber and of course if there were any missing rollers. A good thing to do at this point is to roll the machine forward so that the rollers each roll 180 degrees to see the other side. From this camera angle you can't see the rear most idlers, they are the most prone to chunking and needing replaced before the rest of the rollers.
