Questionhello, well the problem with tractor is, when using the bucket or backhoe it jumps , servicing is good and cant see any leaks, it acts like air in the lines, but bleeder port is clear, changed hyd filter also.Dont want to just change hyd pump unless we have too.
Answerit could be a blocked suction filter or low oil level
it could also be a cracked suction pipe
if you think its a cracked suction pipe you can test this by over filling the hydraulic oil and if the oil is over the level of the crack then it will work properly as it will not be sucking air in anymore
