Technical Coats 20/20 questions

I assume the “inflator” is actually a bead setter. My dad made one to seat beads on his truck tires (22.5’s) and I’ve used it for vehicle tires too.

So take an air fitting and thread the ID the same as the valve stem. Screw it on.
Then attach your air hose to it, and air is just blowing and making noise.
The business end is a 10 gallon air tank, then a ball valve, then a curved up assembly to sorta mimic rim circumference.
135/150 lbs of air in the tank, throw the ball valve, seats the tire enough to let the incoming air at the stem take over.
This is as I assume, like the “inflator” is, ie air up the tank, check. Now work the machine and not use supplied air, but separate air supply as it was filled earlier and hit the pedal/lever.

I could get a pic of my dads set up if needed, but would be in the am.

 

The black end tank fills with air .The lower bottom peddle operates tire inflator hose at 1/2 press .full press empties tank into inflator ring for filling tire to make a bead seal. Right hand peddle operates the tire bead braker rams and center pole spinner motor for mounting and dismounting bar tool . There is parts schematics on line and manuels .you can also contact COATS number is on line also .

 

Hi ERguitar this is super useful. I plan to retore my 20/20 and will put a video together and this will be very important to have the unit working.

I had an old Coats............but it was the newer style..........but it was old when I got it and had been well used and someone repainted it.


It worked just fine, but it was limited as to how large a wheel it would do. Notice the size of the table on it. I figured it was old enough that some of the seals and hoses might become problematic. Weighing it's value against having to deal with any future problems, I sold it. Think I got $800 for it. A friend of mine had bought a new foreign made one and it would deal with larger tires/wheels. He was very happy with it's abilities..........and it looked really nice as well. So I opted for one like his that was on sale. I'm very happy with it as well. The directions however left a lot to be desired, so he came over and helped me put the connections in the right places. Now, I realize my new one is not nostalgic, but it's very easy to use and it will do the tires on the new vehicles that each of us own as well as our nostalgic rides. I definitely don't want to break a wheel on my wife's Rav 4.......can't imagine what a replacement might cost. I also don't want to break any of the new Cragar wheels I bought for my 32 when I mount them. If I remember correctly one of the problems with the old style tire changers was marring the finish, not just breaking them. Just some things to consider before making a decision.
