 Topic: Tractor Accident
Posted: 13 Aug 2024 at 7:11pm |
D17 Series III.
I dropped the front right wheel into a hard hole. I was only in first gear LR. There was no feedback through the power steering or the steering wheel.
My wheel is now twisted. Notice how that knob with the grease fitting is now too far from the wheel.
Everything else looks square: Left wheel, steering rods, two connections to the steering linkage directly below the radiator.
How can I repair this?

Get it out of the hole, get it to the shop, measure the distance between the front tires, set them straight and weld that knuckle on,,,

Might be as simple as a shared key at top of knee. It's a half moon key. May need heat to remove the arm.
Good luck

The woodruff key never shears. It is so hard it rips the keyway out of the spindle and steering arm. It is called a "Hi-Pro" key.

We have owned ac tractors since the first one seventys came out and ive never seen that happen. Ive seen our tractors take some licks that I thought it should have. It amazed me what a interference fit and that key would withstand. Sorry for your bad luck. Hope the repair goes good

You won't know what is wrong until you get the snap ring off and remove the steering arm. Then you'll find if; the key sheared, keyway in spindle broke out, or spindle shaft itself broken. But I believe most likely is the keyway has broken out. Those OEM keys are harder than any from a hardware store. I repaired a similar axle in a late D17 3, it was the keyway, needed a spindle and steering arm, the key looked fine. You might try tractor salvage yards for a used "knee assembly" then all you need do is, jack axle side up & support, remove tie rod end, remove tire, 3 bolts holding knee in place, remove, install knee assembly, set axle width and toe in.

Just for the kicks I’d see if that arm is loose and or will pull up without pulling anything apart.

On my D 15 I replaced the steering arm and spindle. Keyway was worn in both. Alex had the good used parts. Good luck

Is that the problem or did the axle shear off the bolts and slide in?

I'll admit I've done it. Yes, you'll have to torch it apart to get it back apart, but it's broken anyway so nothing to loose by welding it. Only thing I'd add is that you might want to replace the bushings in the upright before you weld, if they are worn, because you aren't getting back in there.

Just a FYI, that "knob with a grease fitting" is actually called a tie rod end.

I had something similar happen on a 4020 years ago. Turned out it was the weld between the spindle, and the axle at the bottom of the spindle. Stuck a post between the frame and the tire, and used the steering wheel to straighten it out. Once I had it where it should be, pulled the axle out, turned it upside down and welded it back together.

Years ago I was working for a guy, had a 3010 JD moving hogs with a trailer,, was on a rocky hilltop ; turned the wheel and the spindle broke away at the bottom end- we both thought - HOLY COW - as we were running that thing daily on the highway!

D17 III.
Here's the result. I have a guy that can do things with metal.
The spindle arm just would not come off, even with heat. My guy cut into the spindle arm, not all the way through to the front axle spindle, and not the full length of the spindle arm.
He was able to remove the spindle arm in this fashion. He replaced the Woodruff key, welded the spindle arm and I returned the axle and all to my tractor. The steering system seems undamaged.
What's left? 1) I am having trouble restoring the retaining nut and cotter key onto the spindle arm and tie rod. When I tighten the nut, it turns clear through. 2) The other wheel is knocked just a tad out of alignment. I know how to correct this via the other tie rod. 3) Persian orange.

Have to push/ hammer the rod end deep as you can - get the nut started, put a vise grips on the end of tie rod bolt end the tighten the nut and pin it

It is not uncommon for OLD tie rod ends to SPIN in the hole when you try to tighten the nut.. The threaded stem has damaged threads... You need to take it out of the hole, hold the taper shaft with vice grips and run a thread die down the threaded portion of the rod.. If its not too bad, you might be able to put the nut on and run it up and down the thread to clean it up... When it screws on easier.... install the taper into the hole, install the nut finger tight, then hit it with an impact.

If you dont have a die you can probably fix the threads with a 3 corner file

Honestly , the look of that angle of the tie rod end- it needs a new one ! Just my opinion
