F700 dump truck, has two cables for dump control mounted in the floor. One engages PTO, the other is Up/neutral/down dump valve. Big red knobs that pull straight up.
With a full box, the dump bed struggles to raise. It makes a loud buzzing sound and jerks in fits and starts. If I load to heavily to the front of the bed, it will just buzz loudly and not raise at all. I have to get pointed down hill to get it to raise and then it's difficult.
With a light load it goes straight up and does it very quietly. All of the hinge points are well lubed and operated smoothly. It seems like some kind of hydraulic problem. When it is skipping and buzzing the PTO shaft does not seem to stop or operate erratically.
Any suggestions on where to start would be welcome.
Thanks,
Greg
