Excellent videos! I have a 763 that is having an odd problem and nobody including bobcat can figure it out. They finally told me i need a whole new control valve assembly for 4k but none are available. Looking for a used one. With the machine running, if i lift the arms up and leave them for a minute, when i go to lower them, its hard to push the pedal and you hear it loading up like hydraulic pressure is building. Once it overcomes the arms drop roughly. This is exacerbated when there is a load on the arms. I have to lift the load up a few inches and then quickly start lowering it. I have to do that a few times to get the load down slowly. If its just a bucket of dirt i can push the pedal hard and overcome whatever hydraulic pressure Is building and it operates somewhat normally. Maybe this issue will interest you, I would really like to figure out whats causing it even if i find a replacement control valve.
