My machine: 1987 Case 580K Phase I (shifter goes through floor)
So I have a leak coming from one of the fat hoses that goes to one of the coolers ahead of the radiator- it's clean hydraulic fluid that's leaking. I'm trying to understand the hydraulic circuits and supply/return line "system". Some questions:
1. There are three cooling units in the radiator area, from front (loader side) to back (engine side) they are: cooler 1 (very fat hoses, one on each side), cooler 2: smaller lines, cooler 3: engine radiator. Can someone help explain what each of the two forward-most cooler elements are for?
2. Mystery: I have a fat hose that goes from the hydraulic filter housing to the front-most cooler element - that's the one that's leaking clean hydraulic fluid - has rubbed through (from rubbing against a steel tube next to it). I do not see this fat rubber hose on the diagrams for the hydraulic filter/cooler - can't figure out which part this is- any help would be appreciated! On the diagram (below) it shows this as a return to tank line, on my machine, this output from the filter head goes to the front-most cooling element...
Help!
