Hey guys, I recently picked up a nice 863C but have a hydraulic hose that needs to be replaced under the seat. (The second hose up from the bottom on the lift arm by-pass control valve) Is there a diagram of the machine showing all of the hose sizes and fitting sizes? or how do you know what to buy? In the past on other machines I have removed them and taken them in but its an expensive way of doing things... I would prefer to figure out what is needed and order one online as it is like 10x cheaper to do this way.... Any expertise on this? Thanks Craig
