4840 oil change question and wiring diagram inquiry

[wec101]

We are trying to change the engine oil on our 4840. Took plug off the line behind the left wheel and nothing comes out. Oil level is correct. Any suggestions? Also does anyone know where I can obtain the wiring schematic or diagram for the 4840? I need to trace where the wire on the back of the aux control box connects to. Thanks for any help or advice on both issues. gc

Thanks---took your advice and it worked. There was lots of gunk. Could I ask you a stupid quesiton? If I understand it the same hydraulic oil used for the hydraulice is pumped through the radiator for engine cooling also? Is that correct? Thanks agian for your advice and help. gc
