BX won't pull a hill-PROBLEM SOLVED!

[dodge man]

If anybody has followed my other thread, I figured out why my BX is having problems going up a hill. This is my other thread, but I thought I'd start a new one. http://www.tractorbynet.com/forums/kubota-owning-operating/240157-bx-wont-pull-hill.html

In the other thread, someone suggested I pull up to a tree and in 4 low, it should spin the tires. I did this once, everything spun. I backed up and did it again, and only the fronts spun. So I put it in just two wheel low, and same thing, the rears are not spinning. The funny thing is, I can hear the engine digging in and a little bit of HST whine. I'm thinking broken axle or something. So I do it again and lean way out and look at the rear wheel. Well the problem is the rim is spinning inside the wheel. I spent something like $116 at the dealer, to have them tell me nothing was wrong. The drove it up and down some hills and never had a problem. I can't really fault them for not finding this problem.

So does anybody have any ideas on how to make this stop? I thought I would raise the rear tire pressure a little. I know this is a problem on drag cars, where the run low tire pressure and get great traction. On them, they bolt the tires to the rim. I'm don't think this would work on my BX. I also have rimguard in the rims, if this makes any difference. I thought it might make the rims a little slippery?

That Rimguard must be some kind of slippery. I have never had or heard of a tractor tire slipping on the rim. Kubota TORQUE!

 

[escavader]

I have heard of this ,what are you running for pressures?

 

[aczlan]

What PSI are you running the rears at?

[radioman]

I have rimguard in mine also- what pressure do you have yours at?

 

[dodge man]

I didn't check it, but I'd say between 12 and 15 psi. Thats what I try and keep it at.

Well hey the good news. is you don't have a broken axle/stripped splines etc that is catching some of the time or something like that
I am thinking air those puppies up to 20 lbs and your problem goes away?

This has been a head scratcher...who would of thunk it?:laughing: I never could figure out why the rear tires seemed to not work some of the time and some of the time they did.. this has been a great learning experience!

I think you should edit your title from "PROBLEM SOLVED" to "PROBLEM FOUND"

That said, I think the best solution might be to pump out the Rimguard, and remount the tires with a liberal dose of bead sealer painted on the rim, then replace the ballast. I wonder if the bead wasn't sealed well in the first place & the Rimguard provided the lubrication to let it slip. In any event, the bead sealer is an excellent adhesive.

 

[k0ua]

I am thinking, (others please chime in) that maybe you pump them up to the max recommended pressure to help seat the beads better and force out the slimy rimguard on the bead. Then leave them at that for a day or 2 to let the slimy rimguard dry on the joint of the metal rim and the tire bead, then maybe lower them to 20 or so for better traction.. what do you think? I am betting they are around 10 or 12 pounds now, and it is just not enough to keep the bead seated hard, you had a little rimguard escape and now it is coated the whole bead with rimguard...

That's a good idea
Rimguard gets pretty sticky when it dries.

Thats exactly what I was thinking. I'm happy its a pretty minor problem, just not happy I didn't figure it out sooner. I described how a leaned way out to look at the tire and thats how I saw the problem. I did this last week when I was first having problems. I have a $100 that says when I did this last week, it was the other tire spinning in the rim and I didn't see it because I was looking at the other side.

Holy cow!!!:thumbsup::thumbsup:

Very informative thread. Let us know how you solve the problem.:thumbsup:

When I was getting ready to put Rimguard in my rear tires, the guy who owns the tractor store near me suggested putting tubes in the tires first so he could fill the tubes.

He told me that the tires can spin on the rims. It also makes it easier to deal with punctures, making it easier to evacuate the Rimguard, save it and reload after tire repair and new tube.

So I followed his advice.

You may want to pump the Rimguard out, dismount the tires, clean everything up and redo it with tubes.

 

[DieselMonk]

My rears on the NH TC55DA are tubed, so are my brothers 3045 and never had a problem with spinning the rim inside the tire. Use quality tubes with a metal valve stem, don't cheap out, other than that you will be changing the tubes soon again due to valve stem dry rotting.

 

[radioman]

you guys are making me nervous with rimguard in mine with no tubes.
What I recommend is follow the other poster advice to reseal the tires with sealer, BUT don't pump it out. It should be easy to work with as its not too hard for one person to manhandle.
What I would do, like when one time I was out at my folks house digging out a stump and the tire stem was leaking rimgaurd where brass threads meets the rubber. I took tire off and took it to my FEL, popped the bead on one side and inserted a new stem. To dodgeman- pop bead on one side, clean that bead with a rag and let it sit for 15 mins to let bead dry and then spray bead with tire bead sealer found at napa or parts plus. air back up and let it sit over night before using. Do same on the other. (tip - look the other way with mouth closed when reseating bead back on rim. don't ask me how I know :ashamed

 

[dougtrr2]

Interesting problem. I am amazed that the rims could spin inside the tires and you weren't losing air pressure. I would have thought the tires would go flat in a matter of hours if they could spin around the rims. Learn something new everyday.

Take Care,

[rmilho]

learn something new every day...thanx! sorry it cost you and we were the learners...but at least it's not drivetrain.

 

[Gary Fowler]

I think James KOua is correct in doing a max inflation pressure based on what is stamped on the tire and leave is that way for at least a week (longer is not going to hurt your tire as long as you dont exceed the max pressure just may loose a little traction) Running it around and working the tractor with max pressure will thoroughly seat the tire bead to the rim. You can then reduce the pressure to whatever you need to get the full tread contact with the ground. You should have any problem after that. I would say that when they put in the rimguard, they never reseated the tire completely which is what let it slip and not the slippereness (is that a word) of the beet juice.

 

[Don87]

Lots of people have a misconcetion that loaded tires need less air, but such is not the case.

The tires need to be inflated to proper air pressures as per the manual.

I personally did pretty much what Gary Fowler said. I overinflated my tires, then adjusted my air pressure so the full tread width was in contact with my concrete garage floor.

I have no clue as to how much air is in my tires,( I can guarantee it's more than 15lbs.) but I do have Rimguard in them.
