    Posted: 29 Oct 2024 at 6:33pm
By gosh, I got both wheels moved with just two jackbolts.  I set them on about 70".  Not close enough for spraying or cultivating (not that it is done much today) it will not be running on a row when planting.  I also think my clamp on duals will narrowly miss the row with this setting.  I had quite a time with one wheel but finally got it. I didn't understand how you could move the wheel by lowering the jack as Lynn stated but after doing it, it is apparent and easy.

Come to think of it, it seems a practice to seed the outside couple rounds (Headlands?) then fill in the center, and that required driving on the outside rounds to make a turn.

I've never seen any tracks in the new growth that looked like where the tractor/seeder pulled over the seeded area.

^^^^I kind of wondered if it wouldn't be OK as is.  I THINK if it is just the edge of the tire it would be better than if the center was running on the row.  If I leave them as is, I would put the duals on.  The duals are clamp on and I am pretty sure the dual would miss the next row and take some pressure off of the inside tire.  The Kinze split row planters have a tire running on the row and it seems they don't have any trouble.

I pull a 12-30 Kinze with my 220 which has 30.5-32's. Outer 10 inches of tire run where rows are. Has no effect on planting or emergence. Just saying.

I don't think that the 7000 series can get down to a true 30 inch setting. The cab interferes. With an 18.4 tire , 31 or 32 inch spacing is about as close as it gets.

Thanks for the info, Mr. Marshall.  I can get two bolts loaned to me.  I need to move the wheel IN.  I am going to use the 7030 for planting and as it is now, the tire runs over the row about an inch.

Usually, I can get the wheel to move with two of the special bolts. With the wheel jacked up, turn it until the axle keyway is up. Back the bolts out of the top wedge about an inch. Completely remove the lower wedge bolts and use the pusher bolts in that wedge. The wheel should move in and then the wedge will continue to be pulled out of the wheel. This way, the top wedge still keeps the wheel indexed to the keyway and then can be moved in or out on the axle by lowering the jack.

Call your local bolt supply store, not a chain store but place that caters to factories, williams bolt used to be around here.  They might be able to order you the bolt special then you can have it machined.

Since you are a Canadian, I can lend you my bolts if you only need to use them one time. See my email on my profile and we can go from there. Also much easier to send pictures if you want to have some made.  Nothing against my American friends but customs is a PITA.

I have come to believe 2 "Might" work if the wedges have been removed recently and cleaned up

BUT in my case, I doubt they have moved since delivered from dealer... so 4 would for sure be required

otherwise I would risk breaking the ears off the wedges

Wont work. You have to move the casting off the wedges. You cant take out one wedge at a time. Get 4 bolts

Could you get by with 2 bolts instead of 4?  Since there are 2 halves, it looks like it might be possible.

Calvin, do you have the specs on the bolts?

how long overall?
how long the reduced section?

Thanks.

I will probably be buying some from a machinist, but I'd sure like to know just for S&Gs

Steve is correct. Jack bolts for the two piece wedges are 7/8" "12" tread. Not NC or NF !
My local Mennonite threading specialist made a bunch for me but Must are sold. He was also able to get me a 7/8" 12 tap to clean the threads in the wedge which is very important. I sold some to Alex at A-C Service in Wisconsin. He post on Facebook regularly and he may still have some for sale

12 threads per inch is an old "MACHINE STANDARD"... used on bolts from  1 inch up to 3 or 4 inches in diameter... Used to assemble big  Steam turbines, big Generators, etc... Different diameters, but EVERYTHING was 12 threads per inch.. I guess it made it simple for the guys running the lathe to cut EVERYTHING the same pitch....

 the 7/8 diameter 12 thread is something of an ODD BALL.. Nobody really used the smaller bolts in a 12 thread design..Leave it to ALLIS to make something you can not buy on the open market.... You MIGHT find a bolt somewhere... but i doubt it.
Like them all, but love the "B"s.

That would likely work just fine if you can find 7/8-12 grade 8 bolts to start with. 14 is the standard fine thread. Now I'm going to have to do some research to see if they are out there.


McMaster Carr would be the 1st place I'd look

That was my thought too Gary, though I did a general Google search first. M/C didn't come up in the results, just looked at the first couple pages. Google, completely worthless, again! I did not find one single 7/8-12 bolt in my limited searching. Lots of 7/8-9 by 12" long.

I'm staying with the E-bay price seems high but really isn't. The amount of time it would take to make a set, provided one has the necessary machines, and figuring out the proper material, and doing a good job of heat treating them. One might be able to make them out of some sort of pre-hard material. That would eliminate the heat treating but makes the machining harder.... I would have to dig the book out to see what type of steel to start with, you sure wouldn't want to just use cold rolled steel!

Dale, that is a very generous offer! Will have to keep this in mind though I doubt I will ever need a set.

That's exactly what I was thinking

some hobby shop with a lathe could probably do it. 
in the listing, they are grade 8

But no one seems to know the overall length, or the length of the turned down portion

I'm going to guess it is quite important to overall strength

Easiest route is probably just to buy those ones on E-bay Steve posted. They can be made but that aint going to be cheap either. Kind of a bitter pill to swallow for a one time thing. If you could find a set to borrow?

He might. That’s where I got mine. Just be sure you clean out the threaded holes before putting bolts in. That will make scrap bolts very fast!

most 7/8 bolts are going to be 9 or 14 threads per inch.. The "12" thread is a Machine Standard for "large bolts" ... but are sometimes hard to get..... You should check if they are available in Canada first... the ones on e-bay might be the Cheapest route.
