If you have seen the first video when he pulls up on site the tyre is well flat and off the bead at the front, I would hazard a guess that the back is probably the same and all he did was push the tyre forward with an air leg/jack. :notworthy I can and have done them myself but not as a first choice My immediate thought is a professional doing his job will make it look very easy, I know from watching different guys do duck tyres, some make a right meal of it, others just crack on and get it done. I'm wondering if too much pressure there might not damage bearings or planetaries, etc? If that's not a concern, a hydraulic jack and blocks should work to break the bead.Ī great find, thanks for posting the links. The video doesn't show it, but I assume that he is placing the air operated bead breaker against the loader frame and then exerting pressure on the tire. He seems to use an air operated bead breaker on the back side. Here are a couple of videos of an experienced fellow removing and reinstalling a 26.5x25 tire. Wondering if they are a waste of time and money. Has anyone tried those products to fix leaks that one can put into the tire through the valve stem? Bars and other companies make products and put out great claims for them. I'm not sure if they charged him again the second time. It cost him six or seven hundred and the tire was flat again the next morning. On the other hand, occasionally I screw things up.Ī neighbor had a flat on his tractor last fall and called the service truck. I'm kind of stubborn and try to do things myself almost always, it turns out that I can find a way to do things. You all might be right about having a service truck come out if this does have to come off. You may be a little paranoid about the ring blowing off, I have never seen one blow off yet, just make sure it is locked in properly and exercise caution when inflating the tyre, don't stand in front of it. The front tyres are easier, because you can use the hydraulics to lift the machine. If the tyre only has a small leak, it can be repaired the same as a tubeless car or truck tyre, but using a larger patch and it is much easier to repair the tyre on the machine. We smear a sealing compound that tyre fitters use around both sides of the tyre to stop the air coming out, until it pushes the tyre out and seals on the rim. Getting the tubeless tyre to seal again when pumping it up can be a problem. You will probably need a new "O" ring, because once it is disturbed, it will be hard to get it to seal again. We repaired one with a leak in it a few days ago and with two of us, we did it in a little over an hour, not that I did a lot. We run quite a few 23.5 x 25 tyres and with the right equipment it is not hard to take them off. I am not saying it can't be done manually, but with a wheel that size, you would have your work cut out. I presume Cat uses the same system as other wheel loaders. You need an air operated bead breaker to push the tyre in off the sleeve on the outside and then push it off the rim on the inside of the wheel. I guess it depends on how far they have to travel. Swampdog, my advice is to ring up the tyre service shop, pay the money and hate it, mind you, $600 sounds a lot of money just to remove, repair and re-fit a loader tyre. Or is that a bad idea?Īny tips on how to go about working on this? Or links to information? That way if the rings blow off the bucket or fork should catch them. And I would put the bucket of another machine up close to the rim or align a fork fastened to the bucket on the other machine inside the rings. When reinflating, I would use a clip on chuck and stand to the side or behind the loader. I probably would leave the rim on the machine when working on the tire. I know that safety is a big issue with installing or inflating these tires. I assume it must have a rubber O ring to seal the metal ring to the rim. But I'd rather not spend the $600 on a service call if I can do it safely myself. OK, I could call a tire shop and have them come out. In the meantime, I'd like to learn a bit about how to fix and install these tires. The valve and valve stem isn't leaking, so it either has a small puncture or is leaking from where the tire meets the rim. So far I haven't figured out where it is leaking from there's snow on the ground and I may not tackle a fix until spring. My 966C with 23.5 x 25 tubeless bias tires has a slow leak on one tire. I looked around the HEF site and elsewhere on the internet and can't find much on repairing and installing loader tires.
