IH 434 Steering Box removal

Analyte · Dec 6, 2019

I'm working to pull the steering box out of my 434 as it's got a lot of slack and needs rebuilt.

It appeares to be a straight forward removal, but it's not working out that way. I've disconnected all the steering parts, plus I've removed the 4 bolts and nut up top that hold the box to the frame. I see nothing else to remove, but it's still down tight to the frame. Is there bolts underneath or elsewhere that I've likely missed?

I've tapped it with a hammer and block of wood so it's not just stuck, I've overlooked something. The model is an oddball in my area so I've had to figure a lot out on my own.

Thanks,
Kerry

Looking at the caseih parts book there appear to be 6 bolts that hold it to the top of the chassis.

There is six on one side, the left side when sitting on the tractor. On the right I can only find two after looking a lot.

Tapping with a block of wood all around, it feels solid on both sides. Even if I missed one, I'm guessing it should twist or move a little at least.

Any idea where the third bolt on the other side could be?

It is stuck on the two dowl pegs if it is the same as the B275 and B414 tractors.

Where are the two dowels located as I don't see them on the diagram? If I know the location, possible I could use a few small chisels to tap between the box and frame to get it unstuck

Thanks!

I got the box out yesterday. I'll have to buy a new steering wheel since I was forced to cut the other off. It was so badly corroded I had not choice.

I started pulling the box apart and it appears to have wheel bearing grease in it. Very think stuff so that could be one of the roads to it's failure.

I found it odd that there is no bearing and race on top of the worm shaft like noted in the drawings. I actually had two spacers instead so only one bearing was used, at the bottom of the worm shaft. It doesn't appear to have been opened up before...

Should I reassemble per the drawings or go back with the double spaced on top? Just want to do what's best.

Thanks
