This is just started happen to me today. It appears that oil is over filled (I am sure I did not do it) and I am leaking around the front of my hydraulic pump. Just happen all at once. Pump still working in that I can move things but it leaks alot more when I have pressure on the system. I have not taken the pump off to see what is going on. Could this be just a seal or do I need to get a new pump? Jinma 254 here.
