Hi,on the bottom of this Case 650K series 2 there is oil weeping from this breather cap on the bottom side of the hydraulic pump.What would be going on in there? thank you.

    Shaft seal going bad either from the pump drive or the pump itself. The breathers are there so you can see when they start to leak so do not just build pressure and cross contaminate or blow out a gasket or worst case hydraulically crack a pump housing.

    No,got rid of machine,and got a new 650 L after,had endless electrical problems with it,until after half a dozen dealer repairs,they replaced the whole electrical harness,and it holds its own now.Case 650K was plagued with electrical issues too.Not impressed much with case,but they are cheap
