leakage of central joint in komatsu w excavator

[Fazli Mabood]

He guys,
I have an komatsu 10h4w-2 wheel excavator. The mqchine wqs very slow in functions so I recently installed a new hydraulic pump but it gives me no fruit. The reason is that since I installed hydraulic pump the oil seal of the central joint is frequently leaking. Then I changed all of the ring kit of the joint and also chrome the joint but the problem was the same. So anybody can give me an advice or lead me to a better solution for it.
Looking to your advice. Thanks
