My 49 6400 grain bed truck has ahydraulic lift to dump the bed. It is run from a PTO off the side of the transmission. It functions well, but there is a slight leak from the pump and seems to be coming from the drive shafts on the front of the pump. Does anyone have any info on these units or know where to obtain data. Also, is the fluid fill for these units located on the big lift cylinder? There is an oval plate on the cylinder held on with two bolts that appears to be the only place large enough to add fluid. I can see fluid in the cylinder. Thanks in advance for any info.
Jim
