Broken Steering on 105

[MiniXP]

I was using my '68 105 yesterday and I felt something weird in the steering, then couldn't turn left. I inspected what I could see out in the yard and didn't see anything disconnected. I was then playing with turning the steering wheel back and forth and snapped that off at the steering shaft, which seems like it is going to be an expensive mistake.

I was planning on going through the steering this winter anyways as it had tons of play in it. Trying to put together a parts list of what I should replace.

So far I know I need IH-401661-R1, which is the broken steering shaft.

I'll probably replace the tie rod ends and any similar joints as those all feel loose.

I've read I should rebuild the steering box as well. What parts should I replace there when I have it open?

I've been using this diagram for reference: https://www.cubcadet.com/equipment/A...0-A/0011500012

That shaft is pretty big to be snapping off, got any pics?

I'll go take a few on my lunch break. It looks a bit rusty so that may have contributed to it snapping.

I've been browsing for parts this morning and am considering just buying the entire steering assembly rebuilt, part 703-1085, if I can find one for a good price. Seems that may not be that much more expensive and would save me the time of tracking down all the individual parts.

Yes, it's a 5/8" dia shaft.
Would take a hell of a lot to break that. I'd suspect a severely rusted worm gear and roller bearings that bound up and finally one of them broke loose.
Has this thing sat out in the elements a lot??
Without a center cap on the wheel?
The 70 I got this summer was like that. The big hint was water running out of the tube once I got it out of the tractor!!

Go through the whole thing including axle channel snug-up and even pin and bushings if needed.
Nothing worse than looking like a drunk trying to keep a straight line while mowing the yard!!!
And, nothing like a nice goot-n-tight steering set up on a Cub!!
Just hope the bearing surfaces on the worm gear are not pitted, but be prepared!!

It was in a metal shed that collapsed under snow one winter, so spent a few months there which caused some rust. Center cap was on the wheel, it didn't break up near the wheel, there is still about 10" of shaft attached to the wheel.

Sounds like it took a hell of a lot from that storage shed!

Is it possible that the storage shed falling on it snapped the shaft? If it is in fact broke in half, then it must have taken a beating!

I'd keep an eye out for a cheap roller and pull the assembly, then keep the rest for parts.

No, the storage shed collapsed like 5 years ago. It sat around for awhile after that, then I've been using it to cut my lawn since spring.

The not turning left thing happened before the shaft broke. The shaft breaking was my own stupid mistake, I thought maybe the steering shaft "unscrewed" and tried cranking it hard to the right, apparently quite a bit too hard as that is when it broke.

So the shaft itself is broke in two completely?

Don't feel too stupid. I know a guy who did the EXACT same thing, except the long bolt/plate assembly (#5 in your link) is what broke. The bolt sheared at the joint of the plate.

Yes, snapped it in two.

Here are pictures:

That sure looks like the tube.... The other side looks like the threaded part on top of shaft is broke off.. Or are my eyes getting old?
