Good Afternoon All,

I am repairing my tire machine. The main o-ring ripped that runs the bead breaker on the side of machine. I was able get it apart fine, get the part was no problem, putting it together was no problem. What i cant seem to figure out is what to use to make it slide decent. I can not seem to find anything on the Coats web site. They wont return my emails, calls. it works but the bead breaker is really hard to use. I have tried a few different lubricants that I didn't think would hurt my o-ring. I even tried something that was meant for faucet o-rings. but nothing lasts.

Has anyone ran into this before or have any ideas. Thanks.

Is it possible that your machine has an oil injector system and you don't realize it ?. I know next to nothing about tire change machines but had gone onto their website and picked a machine to look at the manual and it talks about an oil injector system. See if your model unit is on the website if you don't have a manual and perhaps that may help. It would seem odd that a unit could operate without being lubricated and in fact could be why the o ring had failed as whatever lube was in the system was used up.

Well both of you your replies just hit me with a DUHH moment!! It is an older machining and it was missing a few things when I got it. But adding oil before each use makes total since. I will pre lube the chamber and see how it feels. THANKS FOR THE IDEA!! Will post results

Do you happen to know if the air inlet splits off in such a way that the air used for filling the tire is separate from the air cylinder mechanisms so that it would avoid spraying a mist of oil into the tire. If that can be sorted out and install your own stand alone oiler system might be an option. Also a method to produce dryer air for all of your shop air can't hurt as water is a killer to all air tools for sure.

That is a good point. I do have the air hose and boost of air when setting the bead. I will look at how to oil just the cylinders. Yes I have a dryer right before the tire machine.
