I inherited an early Bobcat 743 SN 5019-M-13744. My hydraulic port block was removed and gutted. All the fittings, valves springs, etc. are gone, just an empty body. I can't find a used port block assy online. I can't find the part number in the parts manual. The manuals I've seen are for a version of 743 that has the port block installed on the right wall, next to the pump. My port block installs on top of the hydraulic pump, towards the front. Does anyone have the part number for the assembly and/or part numbers for all the parts that go inside and install onto the port block?
