john deere 5400 steering

[reinkdl1]

I just purchased a 5400 with 3200 hours and front wheel assist. I drove it to my sons place which is about 10 miles.

On the way I noticed that the JD logo was upside down and the steering knob was at the bottom of the steering wheel. As I continued to drive I looked down and the logo was upright and the knob was at the top. During the ten mile drive the steering wheel went a full 2.5 revolutions.

The steering seems tight and any small movement of the steering wheel moves the front wheels. I didn't notice any looseness in the steering wheel and the tractor did not seem to have a tendancy to drift.

I assume this is probably 100% hydraulic steering and that something in the positions sensing area is slipping.

Is this a dangerous situation or is it nothing to worry about? What would it take to fix it?

Welcome to TBN

Everything is fine...it's just an anomoly of hydrostatic steering. There is very slight internal leakage of the orbital (steering) valve-even new tractors do this.

Thanks, I feel better now. I thought it had something to do with a small leakage somewhere but wasn't sure.

I have a 5400 JD with front wheel assist. My steering cylinder is leaking from both sides, I purchased a seal kit and am about to tear it apart to rebuild it have questions where to begin disassembling the steering linkage. Is there a special tool used to loosen the cylinder rod from the self aligning nut?
Thanks

A lot of times one can smack the steering arm where tie rod end fits in while prying with a bar and tie rod end bolt will pop out of steering arm.
