So this is really a two part situation here but i just picked up an older bobcat 763. So i traded it for some mechanical labor. . The previous owner had it sitting around for quite a few years. They removed the valve body to attempt to repair due to machine not operating correctly but never finished. Not exactly sure their symptoms of failure but i took that valve body and already rebuilt it replacing all the o rings which there were a few o rings blown out on both spool valves so im assuming that was directly related to their issue. Anyways the first question is really a favor im hoping that somebody on here has a 763f that they could possibly take a bunch of detailed pictures or possibly a video of the valve body assembly on their machine and how all the hydraulic lines route to it so i can see if im missing any lines and reassembly this one due to it already being removed when i picked up the machine. They just pulled it apart and never marked any of the lines with where they go on the valve body. I have a service and repair manual but its not very detailed. Anything would help. I called a bobcat dealer near me and they want to charge a grand to just install the valve body on the machine.
Now my second issue is when i picked up this machine the previous owner just lifted the machine up with his excavator and set it on my trailer because of the snow we have had here in nwi. so i figured id mess with the machine on the trailer and get the tracton lock over ride button working at home. After replacing the engine fuse which was corroded as usual i got power to the cab and hit the traction lock button and heard the thud from the release. All is well, or so i thought. Tied the winch from my trailer to machine to verify it was released and got nothing. Wheels skidded accross trailer. so i figured maybe it was locked up from sitting for so long. so i had my buddy tug the machine with his truck so we could get it off the trailer and still nothing.. now im stumped. So my next step was to remove the solenoid and brake completely thinking maybe the solenoid wasnt pulling the brake all the way up to clear it. okay now brake is completely removed machine should roll right off trailer. Wrong. Now im at a stand still and really cant figure this out. What could lock up all four wheels on this machine with the brake completely removed????? The Machine also has a foot brake which has a switch on it not exactly sure how that operates? Any help and input would be greatly appreciated!
