IH 856:How do I remove the inner duals from the axle shafts?

Hi, fellas:

We had an uncommonly cold snap here in Southeastern Arizona, and the water in the rear inner tubes on my IH 856 froze and broke one of the inner tubes. I jacked the tractor and blocked it up, but now I'm stumped; there's one large bolt with a splined 7/8" head that runs through the wheel and clamps it to the axle shaft, but I turned it counterclockwise about four turns and it bound up again, and I can't get it to go anywhere except four turns clockwise, four turns counterclock, even though I've put some pretty fair torque on it with a four-foot cheater pipe.

Anyone know what's going on here?

Thanks in advance,

John-Henry

You have wedge-lock wheels.you need a speacial tool to complete the job.(you can make one-I did)Turn left till tight,smack bolt head with big hammer-repeat-use a 10Ft cheater.You might get lucky.

By "inner duals" you mean Primarys,right?

My 1066 had a wedge on either end of that bolt. You unscrew the bolt to push the wedges apart. There should be a pair of horseshoe-shaped plates that are fastened to the hub to prevent the wedges from pushing out too far. Also, turn the wheel so that the bolt is on the underside of the axle, taking weight off the wedges, making them easier to move. The horseshoe plates will be stored on one wheel or the other.

If you had the book,this question would be already answered.order one.

If you are only wanting to repair / replace the inner tube you do not need to remove the wheel from the tractor. Any qualified farm tire technician has the needed tools to do this repair. You will need the outside dual removed. I have fixed many of them this way. Happy trails...

Tractor tires are much easier to work on when upright and mounted to the tractor. Why are you trying to remove it?

Yes, those wedge-lock wheels require that special tool. You'll never get it done without it.

Loosen the lock bolts, turn in the push bolt til tight. whack the axle shaft on the top with sledge and turn the wheel while hitting. Every now and then tap the 12 point lock bolt in a little. You will not knick the axle its hard as "the hubs of he!!".

First of all I"d like to thank everyone who replied this this question; I"ve used the "Net for a lot of things, and I figured that if I managed to find the right Discussion Board I might get an answer or two, but I didn"t expect this kind of response.

I ought to say that I"ve owned this tractor for ten years or so; bought it from a neighbor who had quit farming, and I probably haven"t put 40 hours on it in those ten years. I"ve used a ripper to tear up a little bit of mesquite, a disc to turn a few acres to exercise horses (and to make a soft spot to land when I"m riding the rank ones) and a big drag to smooth out some rough spots.

I"ve got a 17-acre irrigation right on the place, though, and I"ve decided to put in some permanent pasture, but as I said we had a heck of a freeze down here a couple of months ago, and it broke three of the four water-filled tubes on the tractor. The two front tires needed their tubes replaced (10.00 x 16"s) and I ordered them in a couple of days ago, but when I turned my attention to the rear tire I realized that I was getting into deep water.

For example, I didn"t know that it"s easier to change out a tube with the tire mounted to the tractor; we have a little old shop not too far away, and the fella there told me to pull the tire, bring it in, and he"d fix it for me, so that"s the direction that I was headed.

So, here are a few (new) questions that I have for ya"ll:

1) DeltaRed says: "You have wedge-lock wheels. You need a special tool to complete the job.(you can make one-I did) Turn left till tight, smack bolt head with big hammer-repeat-use a 10Ft cheater. You might get lucky.

And Rustyfarmall says: "Yes, those wedge-lock wheels require that special tool. You"ll never get it done without it."

But Redtom says: "Loosen the lock bolts, turn in the push bolt til tight. whack the axle shaft on the top with sledge and turn the wheel while hitting. Every now and then tap the 12 point lock bolt in a little. You will not knick the axle its hard as "the hubs of he!!."

And he doesn"t mention a tool at all.

I"m not trying to come in here and start a fight between other members, but who is right here, and if I do need to build a tool, what does it look like and how does it work?

2) Then a couple of other fellas say that I don"t have to take the tire and wheel off at all, which sounds fine to me, but what do I need to break it down in place? We don"t have any mobile tractor services in this part of the world, so I"m kind of on my own, although like most rural places there are plenty of fellas around here that are used to doing a lot with a little, so I can probably beg or borrow whatever I might need.

And by the way, I can post pictures if it"ll help; I"ll just have to fool around a little bit and find some server space.

Thanks again,

John-Henry
