Case 930 Split

Walt7777777 · Jul 11, 2008

I need to half my case 930 to replace the starter gear on the flywheel. Does not look like alot of bolts holding it together. I do not have a stand to mount the halfs, but can weld something up. Anyone have any ideas they can share with me on getting this done.

I know you have to heat the ring to get it on, I'm told a torch will do, but what is the easiest way to get it off.

Any help appreciated.

Thanks,

Walt

disconnect everything between the halves (lines, wires,etc) , remove sheet metal, front axle and wheel assembly, all fluids. On my little allises, i've gotten two people to hold it and lower it. and i've used used a front end loader when there wasnt any body around.

Lanse,

Do you have ANY idea how much HEAVIER a 930 Case is than a little Allis "B"???

And, yes, I HAVE split several 930 Cases over the years.

On a tractor that heavy, I'd be inclined to let a shop do it, with the proper equipment. Best way I've found to do splits in general is to suspend the front half with a sling from above- this will prevent it from flopping over sideways on the bolster shaft when the two halves part. Back half with a heavy floor jack underneath, preferalbly with a transmission cradle or some such, and roll it backward by just pulling on the rear tires.

Can be done with stands, but I highly recomend a over head hoist for the front end. Not that bad if you go at it right on a concrete floor with a hoist.

Nope. Im just running ideas here

It's an old tractor but low hrs, can't really afford to take to a shop, I am a farmer.

I have an old bull dozer I could support the tractor with, but a case 930 weights around 7-8,000 pds with the loaded tires. It has a wide front, so I don't think it would roll over when split. There are threaded holes on each side of the back half that I could bolt a frame onto, not sure how I would suppor the other half.

Can someone who split a 930 let me know how they did it?

Thanks,

Walt

Many years ago I split an International 856 for a clutch job. Didn't have a concrete floor, so we laid down planks on the dirt. Didn't have the proper stands, so we improvised with a floor jack and a few chunks of wood. Needless to say the only good that came from that project was the education, and it was an expensive education.

Lanse, your Allis B is a nice little tractor, but it could almost ride along as a passenger on that Case 930.

I wouldn't attempt it on something that big with anything less than an overhead hoist and a good floor jack.The second tractor that I ever split was a G1000 Minny Mo,I was about 15 when I did it,Dad did help seperate it and put it back together but he was never much on mechanical things.It's not a terrible job but be careful.

With a wide front tractor,I've already used wood blocks between the axle and frame to keep them from tipping,they will tip some because of the axle pivot.It isn't a huge problem until you go to put it back together again.If you support the front end real solid,with stands near the rear of the engine,you may be able to roll the rear away on a good floor jack.The problem with that is,when you go to put it back together,you've got to be pretty gently,if the front is hanging securely in a sling,you can horse it around a lot more to line things up.

Lance just to give you an idea of how heavy a case 930 is. Your B Allis is around 2000-2500lbs but a case 930 is around 4 or 5 times more or in other words around 8000-10000lbs

I found out that putting a ring gear in an oven at 500 degrees and letting it sit there till the oven reaches temp then dropping it on works real nice. You can also freeze the flywheel but when I did a ring gear on a TO20 a couple weeks ago I found the freezer thing probably would not have been needed. The ring gear I did dropped right on and in about 30 minutes had cooled to the point that it was good and tight but the froozen flywheel may have speeded the cooling a bit

The wide front won't keep it from flopping over- you know how, when you hit a hole with one front wheel, the axle tilts as the wheel goes into the hole? That's because the front end is suspended on a longitudinal shaft called a "bolster", and once the front half of the tractor is not attached to the rear, there's nothing to keep it from flopping over sideways if you're jacking from underneath. With fairly disastrous results.

Tractor is over 10,000 lbs. if the rear tires are loaded. You also didn't state which version of 930 it is and that will make some differences in what is required. I have split both 6 & 8 speed 930s. If I recall correctly, the steering column will also have to be supported separately. As previously stated, use wooden wedges between the bolster and front axle. Use long splitting pins or 3/4 in bolts to get and keep things lined up. Be particularly careful bringing them back together or you will damage the oil seal in the end of the crank. You should seriously consider replacing the clutch disk at this time as the labor is exactly the same. It is a 2 person job to roll the halves back together. I am puzzled that your ring gear is shot as I have 1 w/ over 25,000 hrs and 1 w/ 15,000hrs and neither has had the ring gear turned or replaced. Buy the I &T shop manual before starting, be extremely careful and good luck.

I did a case 1490 a few years ago. I am lucky to have two heavy duty 4 wheel floor dollies that I cribbed up to the housings from. so it was just a matter of jacking up then taking the weight with wedges on the cribbing then pushing the rear back. some extra air pressure helps here. Be sure that the casings are level before you pull them apart, pushing together is tough if they're not. I did it all myself except that a friend came by just as I was about to push back together. But it was pushing easily anyway.
