You are welcome. I hope that it goes without a hitch.

Thanks again! It's back to it's non-leaking self.

Thanks. I did make improvements to this machine. The video is on my channel. It is called: DIY Tire Changer - Improved V5.0

no need to be a jerk

You are correct. The Kawaski 650 and the Nija use a 15mm(0.59”) front axle and a 17mm(0.67”) rear axle diameter. If you had the skills/equipment to build the tool, it would be a simple task to change the machine axle to 0.5” diameter with the proper sized flanged sleeve bearings. I sized the tool to handle the wheels that I would put on it. To date I have done 3 different motorcycles and multiple automotive style wheels from 13” to 18” in diameter.

@@joejoe9773I think it’s safe to say that most are in awe of your ability to build the tool. Good job! Whatever I cobble together will be a bastardized mix of the Pittsburgh machine, a duckhead mount/demount bar, and a 15mm center post from McMaster. ;)

I used rattle can spray paint made by Rust-Oleum - "Professional High Performance Enamel", 15oz cans. I also used their primer. It has held up well. After I quit banging the wheels with my tire spoons, I re-touched the wheels with the same paint. I have painted the other 4 wheels, after I changed the tires (you learn as you go). The motor home does not see use in the winter.

How do the beads get stuck? I have used beads on multiple motorcycles, automotive tires, trailer tires and motorhome tires. Thousands of miles of use and no off balance detected. No one is paying me. Do what works for you.

Cost savings. Harley recommends new screws if you pull the old ones.

Thanks. I did not make it to sell. I made it to share ideas with other people that are building their own machine.

I tried the changer on a dirt bike tire. It did not work. This wheel had a pair of rim locks installed. The rim locks got in the way of the duck head. So, I used tire spoons. A steel wheel was mounted on the changer. The dirt bike wheel on top of that. A bit of overkill, but it did get the wheel at a better height than a plastic 5 gallon bucket.

I bought the duck head and clamp protectors on Amazon. I added a link to both in the description of the video. Hopefully, the link works for you.

That top support arm made a big difference. Everything stays in alignment as the duck head is rotated around the wheel rim. It seems easier to rotate. I wonder if I could have stayed with the 3 clamp system.

When I had a stubborn bead, I have been able to get it to seat by bouncing the tire/wheel on the ground. I don't go over 40psi, the bead area still has some wet lube on it and my tire bouncing is not very gentle. I hope that helps. Some people break the bead again and try reinflating the tire.

I like that. I have been working on learning the limits of my machine and then improving it. I have gone from 3 clamps to 4, added an overhead arm to support the machine's axle and improved the duck head attachment. This new version should be posted next week. I will have some simple sketches with dimensions at the end of the video.
