1800 C Steering Issues - AGAIN!!!!!!!

As I posted a couple of weeks ago the steering on my 1800 C stopped working correctly when I was planting pastures. I removed the spring and plug from the front side of the flow divider along with the spool from the back side and buffed it with brown paper then replaced it. The steering worked correctly again.

Two days ago the steering became sluggish again so I removed the spool and rebuffed it again, but it did not improve. I then removed the plunger from the front and replaced it; This 'fixed' the steering issue.

Yesterday I was cutting hay and the steering became sluggish again, but corrected itself when I had the wheel turned all the way to the right and was lifting my mower conditioner. This lasted for about 5 minutes when the steering became sluggish again.

What could be causing the problem? Without the power steering it is quite difficult to cut hay, especially with a center pivot NH 499 when you are cutting in passes!!!!

Well if you removed the "plunger" which I am guessing is the poppet for the relief valve for the power steering and the flow divider spool stuck again You may have a lot of fine cotamination in the system which is causing the spool to stick and the plunger to leak while it is seated. Also how warm does the unit get? First thing I would do is change the filter, buy an extra filter and change the fluid. In about 20 hours of operation, I would change the filter again. do you have the free travel in your 3 point adjusted properly?
 

J:

I changed the filter the other day when I removed the plunger, but did not change the fluid. I will try that.

I have done nothing to anything on the 3 point hitch. I did use it this spring on a packer.
