I know that the pins fit from the outside before ballast and that the tires are an 1 1/2" to 1 3/4" wider now. I hadn't realized that the video (same tractor as mine) was set so wide. For stability's sake it wouldn't hurt to widen the stance but I'm certainly not equipped to remount the wheels myself (especially with 550 to 600 extra lbs of ballast each). Is my best bet to get it back to the dealer?

This makes no sense. It is impossible that the tires grew to that degree. Did you watch the guy fill them?

They were filled in my presence, on the tractor while jacked up.

Then I can only say that you had been inserting the pins angled in the opposite direction and the curvature of the tire on part toward the axle gave you room to make the installation from the outside.

After my tires were filled the the tire man with plenty of experience lowered the pressure to 15 #. He said it to take into consideration there's such a small area in the tire to hold air . I've forgotten the rest of the details.

Only issue with the inserting the pins from the inside is the likelyhood of something snagging the linch pin out.

That said, you have a FEL. It doesn't take much of a bump or hole (DE may be flat but I'll bet it has holes) to tip over a tractor... especially when using the FEL. I would set the wheels for a greater width. As said before, another set of hands & a hard flat surface makes changing the tires easy.

If you insert the pins from the inside I would use a nylock nut and bolt to retain the pins.

I run 16 psi on my 110tlb rear tires without ballast added. My 4520 is 14 psi with 330 lbs of iron on each rear wheel. Don't understand why you need so much pressure?

FWIW, Deere does not recommend adding ballast to the rear of my 110tlb for backhoe use. You might inquire about this with your dealer to make sure it is okay to do this with your tractor and hoe. Adding 1200 lbs to the tires may make it harder to pick up the rear wheels with the hoe when repositioning or moving off a ditch.

Thank you all for the advice. It works fine with the pins on the inside. There is nothing in the 485A manual regarding either ballasted tires or wheel mounting positions. Having said that, I think that I'll have the wheels remounted to the 6th position from the 4th if for no other reason than stability. I don't see buying an engine hoist for this one project especially when I use my FEL for all other lifting.

You are trying to insert pins away from axle. Insert pins closer to axle. Inserting from axle side closer to rim not tire into outside hole should work.

Is it possible to insert the pins into the outside frame, just thru the first flat bar till flush, then back the tractor back between the frame mount. Could this have been how you disconnected it the first time. That is the only way I see that the pins could have been removed from the tractor the first time around

With the ballast in the rear tires can the hoe pick up the tractor rear end and move from side to side?

Are those welds or super glue ? That is possibly the worst factory weld I have seen .

I was wondering the same thing. Looks like the tire's cross section is narrower, at rhe radius from the axle where the pin goes.


Rather than tryng to get the pin into the hole from the tread side of the tire, try it from the bead side.

 

[Junkyard Jim]

drc343 and Baby Grands will be an easy thing to check, but Gary beat me to it about putting the pin in part way first. Even if you have to put it all the way in until you get close, ie past the fattest part of the tire, then pull it out to get it to clear. It may mean another time off and on the tractor, but if you want it to go that way, it may work.

Keep an eye out on craigslist for an engine hoist. They are handy for a lot more things than you may think and you could have remounted your wheels by now.

Good luck with it, Jim

Yessir - how'd I miss that?

Just like there is more than one way to skin a cat, there is more than one way to say the same thing. Full credit to Spyderlk for pole position.

I'm grateful for all the responses but there is no angling these pins in. I posted pics back on post #29. The lift arms really have nothing to do with the pins except that they are used to lift the frame attached to the backhoe so that it aligns with the frame attached to the tractor. For lack of a better description, the attachment point on the tractor is fixed (doesn't move) and is "male". The attachment point on the backhoe is "U" shaped ("female") and is lifted into alignment by raising the entire backhoe frame with the lift arms. I might be able to start the pin into the backhoe frame before lifting it into position and inserting it completely when in position. This would gain me the width of one side of the "U" (maybe 1/2" at best). The problem would then be removing it later. I obviously would not have the space to get it out. I could end up in the position of having to remove the wheel in order to get my backhoe off. Remounting the wheels is my best bet, with the easiest fix being to keep inserting the pins from the inside and secured with a bolt and nylon nut instead of a simple snap pin. I'm not very good at explaining things but if you look at my pics in post #29 I think you'll see what I mean. Thanks again for all the advice.

So we are stuck with magic as the explanation. :confused3:

 

[Jsandy]

Well, lets try this explanation on for size. How about my CRS is acting up again and the tractor was actually delivered with the pins on the inside and I didn't notice. When I went to put it back on 6 weeks later I read the manual to refresh my recollection and "remembered" that my dealer delivered it as per the manual. My consternation/frustration at not being able to install the pin correctly caused a massive brain fart which led me to not consider that my dealer delivered it "wrong" because they didn't take the time to remount the wheels when they couldn't get it pinned correctly. Not magic, I just can't remember sh%%. That, and I trusted my dealer (silly me). If the pins can't be inserted from the outside (and they can't), and it is impossible for the tires to have expanded (and it apparently is), and it isn't magic (which it probably isn't), I can't think of another explanation. The solution still remains remounting the wheels or living with the pins on the inside.

CRS huh - it happens to the best of us!!! LOL
Thanks for giving up the update

 

[bigdeano]

You could rent an engine hoist for a day for not very much. Then you wouldn't have it laying around taking up space.

 

[MMagis]

I think your most recent theory makes the most sense.

In regards to changing the tire position, if you have a decent garage and a couple of specific tools, you should be able to do it yourself. I mounted one of the loaded tires on my Ford 3000, smaller than yours but the same method should work. Especially since you don’t really have to move it much. I put a piece of heavy pipe in the rafters, attached a pulley to it, and then used the winch on my Ranger to keep the tire upright. If you have to move it, I put one of those cheap frames with casters from TSC under the tire. I had a buddy there with me, just in case. But from trailer to mounted only took a few minutes.
