Main hydraulic pump tests correct output pressure at the right side test port. It tests no pressure at the left output side port. Is it common for one side of the pump to go bad? Or could it be a stuck bypass valve that is only servicing the left side valve body? I haven't seen any metal flakes in the fluid so mainly curious about pump failures for one side only and without obvious metal wastage? Thanks!
Which model of 307 exactly.? There are 23 different ones listed. A Serial Number would remove all doubt.
