Coats 70x Tire changer

[outlawspeeder]

I bought a tire change machine and need to build the swing arm for it.
Looking for someone that has one or access to one to grab some measurements.

The swing arm is the one that mount and unmounts the tire and has the duckhead on it...
Need to know;
1. How long the arm is, pin to pin.
2. What size is the arm and wall thickness.
3 How long the vertical part is with wall thickness.
4. The length of the 1.5 x1.5 moving part.

Photos will help.
I've ordered the spring and the duckhead. The cost of the Arm is just out of control for something that can't be more than $50 on steel.

Thank for the help.

You bought a broken tire machine that's missing the entire mounting arm?! Do you have the locking mechanism?!
A picture of what you have would help other members I'm sure. I have a different model of Coats machine but in general the swing arm will extend to the exact center of the table/platter where the wheel sits.

I need to clarify my hobby. I rebuild things for the cheapest I can. From purchase price to all parts needed. I've build a complete machine shop this way. (thisisjust4fun.weebly.com)

djbmw,
I would say I got a good deal for $400 and the only thing it need, is one arm. I can get the arm on Flee Bay for under $300 the rest of the for under $200. I figure I can weld up what I need for under $50 and do my own machining to make it work. I looked at broken 70x for 2k or more.
So the Arm length goes from pin to center of the platter. That's one spec I needed. Thank You. Thoughts on wall thickness for the arm.

TY. I found that and in a couple of places. Would like to find the drawings but I think that is asking too much.
I might have to do some work in Fusion 360 and post them for the next person.

Background on the Coats 70X, It is one of the most common models made. Damm near ever tire shop has one or two. There is even a business rebuilding these and selling them for over $5k. If you are not a fabricator, you can buy any part for these. It will work on tires from small garden tractors to 22" wheels. It will even pull tires from motor cycle wheels without have to pull the rotors. What I bought it for.

This is what I have but without the tire lift after breaking the bead. The arm information I am looking for is the one used to dismount tire.

I used to work in a tire shop. I wouldn't be able to use that machine. Too complicated.

They come a long way. In 1983 in Kmart I was spinning a nut down on one these bad boys.
