1981 John Deere 2040 with over heating problem

Oletrapper · Aug 5, 2008

I have a 1981 2040 JD which has a problem with the hydrolic fluid over heating. The power steering unit below the steering wheel gets so hot you can not touch it without getting burned. I have changed the fluid and replaced the filter and cleaned the screen. I have cleaned the radiator. There is no hydrolic cooler unit on this tractor. Just a large canister in front of the radiator at the top. This tractor was purchased new and only has 1600 hours on it. Any suggestions?

The only time hydraulic oil should flow through the power steering is when the steering wheel is being turned.
Is the steering assist the plain power steering system or the optional hydrostatic power steering?
The deere web site has a parts section.
Is the tractor Mannheim or Dubuque built?

Oletrapper,
If power steering valve is that hot it's probably causing your heat problem. You could eliminate steering by temporarily capping line on rh side leading to steering valve. A high pressure internal hyd leak is going to be in the steering,rockshaft or if equipped scv's.
