401 Case Power Steering

I have a 401 Case diesel with power steering. Each time I want to use this tractor I need to fill the PS tank since it leaks out. I have this tractor in the shop to look at this over the winter and get it fixed. Does anyone know of a common leak these units get or a good spot to start looking. I also need to work on brakes so also looking for tips in this area.
Thanks, DJ
 
Look to see if oil is running down the pedestal, if there are no leaks in the pump area and hoses I'd bet on a bottom seal leak. Could be a seal on the steering shaft also.

Mine was doing that. I suspected the bottom seal but after closer inspection I found the drain plug on the steering unit was leaking. Put teflon tape on the plug and cured the problem. Hope yours is that easy.
 
In the last 2 issues of Old Abe's News there were articles in there on brakes and power steering pumps. If the steering gear leaks out I'm planning a future article on that.
 
I redid the brakes on my 401. I took the footboards off to make it easier to see what I was dealing with. I replaced the boot on the rod that comes out of the housing, and the springs and balls in the actuator assemblies. I also replaced the seals on the shaft that comes out of the differential. The hardest part was getting the covers off and put back on.
