434 steering box

KenS · Feb 19, 2009

Im trying to remove the steering column/box on my 434 diesel.
Anyone thats done one , do you remember how many bolts held it on?
Ive take 4 bolts that are 5/8 wrench size off.
Also I bigger nut that was on a bigger sized stud.
So all together Ive taken 5 things off and its still so tight it wont wiggle?

I think you will find there are 2 dowel pins holding the steering box on. They should look like a threaded stud sticking up (the larger nut you removed was on one of them) If you put that large nut back on and tighten it down, it should pull the dowel out. The dowel is 1/2" but the thread is larger.

Thank you thats exactly what I did.
Ive got it off and torn apart.
Looks like a bearing gone but its been gone for so long I cant even tell where it went.
No oil at all in box just pieces of a bearing.
Anyone know where the bearing went or if I can even buy a bearing?

Ken,
The bearings (both upper and lower) consist of a cup, some loose 1/4" balls and then they mate up to the sufaces on the worm gear.
The cups and balls should be available from any CaseIH dealer.
Don.
