On my red one, sometimes the steering locks solid for a couple of seconds, anyone had this, dealer could not find anything wrong,surprise surprise.

Yea before they changed ours they disassembled it and there was apperently nothing wrong with it.
Brakes had be done on ours aswell which is interesting.

Does it ever go tight or feel like it's going to lock up? Use to work for a company running lots of NH's and had similar steering issues with T6's and 7's. After numerous visits and parts changed it turned out to be the actual column. Something to do with a bearing just under the steering wheel. May not be your problem but it's one of the most unlikely places to check.
What age is it?

I seem to remember once or twice it going a bit tight, its something I will check when I change the orbital unit and its in bits
Was your tractor still under warranty when they replaced it?

There's a part fails between steering wheel and linkage. It's behind dashboard. We oiled ours for a bit then it was eventually replaced.

No it was about 4-5 years old bought second hand with 3000hrs in it

Just to drag this old thread back up, I ended up changing the ram seals and I fitted a Intellisteer kit that included a new orbital . The steering was night and day difference after this however someone else was driving it the other day and commented that its very hard to keep it in a straight line, it needs constant adjustment to keep it straight.
I never really noticed as it's the only tractor I drive these days, I'm trying to think back if it's been getting gradually worse or if it's been like this since I changed all the parts above. My cousin who occasionally drives it thinks it's been like that all along and it's like that due to the intelisteer plumbing.
Can anyone else comment on the above? Now it's been pointed out to me it's actually quite annoying.

I have a T7 with the steering valves and it steers just fine. No different to the virtually identical red version with no steering valves fitted that we also have
Does the steering self centre or not in use?
If not it's not right

I had that on a 7060 seems the orbital wasn’t suited to the pump
Not a good experience when you turn and nothing happens

We had the same on a puma 195 2007 year Wondered about on the road
had to get used to it
the current t7 260 And 210 Are much more positive
I have had the steering column linkage on a discovery 4 go stif Replaced the iinkage
also on a sprayer column
so in future when steering goes stif on any machine will investigate the uj in the column first
simple cheap solution before looking at the expensive hydraulic bits
most steering columns have a uj. linkage now steering columns have adjustable rake
I also had a 40 series new holland that had electrical problems where the wiring was chafed by the steering column
being tall the column is always at full length on any machine I drive this stretches the cable if they are not over long

I tested it and another T7 today, mine doesn't self centre at any speeds whereas the other tractor does. Have you had similar issues before to mention it?
Funny you should say that as it got me thinking today. When the steering kit was ordered it was against the tractor serial number however when box of bits turned up all the interior trim parts were in Case colours. Everything fitted correctly but now i'm wondering if the orbital unit isn't correct as you say.
I did check that when I replaced the orbital unit last time but it's worth checking again

I have a retrofit auto steer kit fitted to a NH t6.
We had to fit an isolation valve to it as it was bloody dangerous without it.
Once fitted it was back to normal.

Tracking was the first thing done and it was miles out! Tyre wear has been spot on since.
Interesting, any pictures where you fitted it? The valve block is mounted directly on the orbital unit in this instance so I don't think its possible to do, even to test. I will have a look at hydraulic schematics now and check though.

Look like this answers my question
Quote from the workshop manual - The steering unit is of the non reactive type
And this is from google -Non-load reactive (non-reversing)— The non-load reactive steering unit keeps the steered wheels in the steered position when the operator releases the steering wheel. The cylinder ports are blocked in the neutral valve position. The operator must steer the wheels back to the straight ahead position.
