Answer -
Frank did you change the oil as well as the filter if yes tell me what oil you used to refill the system again as this may be the problem.
I await your reply to this question.
No I did'nt change the hydraulic oil in the transmission/rear end when I changed the filter, I use 134 type hydraulic oil, could it be a value or main pump? thnaks. Frank Regards Danny Last
AnswerFrank the best thing to do would be to have a flow and pressure test done on the pump this will let you know if there is a pump problem.
You will need to contact a hydraulics person to do this test.
With not being there to look at things and see what the simptombs are it is hard to pin point it Frank.
