Will radius rods from N series fit 800? I have
heard they can be stratened. How do you do that?
Here is a pic.

I straightened a pair of rods just like that on a TEA 20 in a hydraulic press just fine. Just move them along not all pressure in one place

Forgot to mention. Fixes the castor so tractor steers much better

No.
Hundred Series radius rods are much longer than those for an N.
I'm guessing 4 or 5" longer.

Wow! Those look like Robin Hood's bow ready to release.
Yes, they can be straightened. A hydraulic press works. I don't have a press (though I have used one to straighten them), so I use an 4"x6" timber with a 20 ton jack resting on the timber. Using a short length of channel iron 6" to 8" in length, rest the radius rod in the channel iron. Rest it on the jack and then chain the radius rod to the timber.
When straightening, go very slowly. Allow time for the radius rod to adjust. For something as bent as yours, I would give yourself several hours of small adjustments. I have heard that no heat should be used. On the other hand, one radius rod on my daily worker at the farm was nearly snapped in two and my friend successfully welded it back together. That was nearly 8 years ago.
Slightly over-adjust as the rod will want to return to a slightly bent shape.
BUT...no point in fixing those radius rods until you have replaced the worn king pin and bushing that caused the bent radius rods in the first place.

You can straightened it. But in my area they can be had for cheap. Look around. If you can't get a good deal on one, fix yours. But once fixed it will not be as strong as it once was.

Time isn't a part of the equation Colin - unless you work very slow 
When we still had access to the giant machine shop we could do one of those in a couple of minutes.
Alas, it was all auctioned off. Photo is of the 600 ton hydraulic press they had there.
Made short work of it.

UD - And you didn't snag it?? :-( I bet that press did the job nicely. I had heard otherwise-that going slowly would reduce the stress on the metal and reduce the chance of going to far and damaging the radius rod...

Hey Chum,
I got one you can have....just pay the postage

a couple 2x4 pieces, some chain and a bottle jack will re-bend that rod, bend it past straight a hbit so when it relaxes it will be straight-ish.
use the wood to spread out the contact point of the bottle jack.
bow down, use chain under the jack and up to each turned up end.
crank away

I once worked at a place that had one something like that when I was young. We use to put pennies in it to see how big they would get. We were making our money grow :/

Two tree's about a foot apart with another tree directly behind the first two. Wedge the arm between the first two tree trunks so the bow in the arm is facing the third tree. Hook up one end of a come-along to the end of the arm sticking out and the other end to a chain wrapped around the third tree.
Tighten the come-along as fast or as slow as you want until the arm is just a hair passed straight.
Cant tell you how many chrome bumpers I straightened out this way or how much 1/2" flat stock I formed bows in. The bigger the tree trunk the bigger the radius of the bow.
