Steering motor leak

The steering motor on my 1955 has been leaking a little for a while and I haven't been able to pinpoint where it is coming from. But recently I have seen hydralic fluid coming from near the top plate. Does this mean that the bolts need tightening, or does it need a new gasket, or what? Any help would be appreciated.

It is my understanding that Oliver used a Char-Lynn, closed center, steering motor on the 1955. Your description "top plate" sounds like where the steering column mounts to the top of the motor. Tightening these bolts won't help with a leak. There is no gasket between the column and motor. The motor is sealed internally. Here is a picture of a Char-Lynn motor with the steering column removed.

If you remove the steering column and find fluid leaking out of the top of the motor, an internal seal is probably bad.

I'm not sure what series motor was used in the 1955. Hopefully there is still a Model/Series number plate on the motor or maybe someone else will know. This is a link to Eaton's web site. You can download Service and Part Manuals, in PDF format, for your motor.(You may have to do a SEARCH for your particular motor.) Parts and repair kits are available.

Hope this is of some help.

I'm talking about the unit just behind the radiator.

Oh, Okay. That's the steering cylinder. Yes there is an o-ring under that top plate. You can try tightening that up. If your noticing leaking fluid underneath the tractor, in the area of the pitman shaft and center steering arm, I bet you've got a bad Quad seal. All O-rings and seals are available from AGCO or Rick's Agri-Parts.

The 1955 had one other problem too.There should be a leak off line comeing out of the cap so high preasure can't build up and break off the cap.Make sure the line is open and not capped off,if it is oil can get pushed out top and bottem.
