Farmall 140 losing hydraulic oil

Red Dog · Aug 8, 2009

I had a Farmall cub that used to leak hydraulic oil into the engine oil because of bad o-rings at the pump. My 140 hydraulic tank is running dry over time and I do not see any external leaks. Does the 140 suffer from the same o-ring problem as my Cub did. Can it be possible that my 140 hydraulic fluid is leaking into my engine? Thanks----

Of course thats where its leaking just like the Cub. Remove the pump and thats what you will find

You may need a speedi-sleeve if the old seal has worn a worn a groove. Your pump may be similar to this. Hal
