This was supposed to be posted the other day but somehow I forgot to press the "Post" button.
I've mounted up another set of 020's this last weekend. The shims I made for the receiver hitch worked perfect. They virtually removed any twist flex in the mount. As mentioned earlier I wanted to set it up so that one of the arms was directly in line with the mounting bar from the vehicle. The problem was that the the height adjustment was in the way. What to do now? Well, I took the rear tire I use to keep my jack from sliding around the bed and threw it under the Tire Stripper with a piece of 3/8" plywood on top the tire to form a platform of sorts. Now the height adjuster was above the mounting plate and it bolted right up. My thought was that the first area of bead to break is the hardest and with everything in line, vehicle mount bar and platform arm, I would get the least flex or twisting when mounted to a vehicle and not the ground. This also worked.
The front tire went on without a hitch. I must not have had enough Wheaties that morning because I needed a little help pulling the bar to get the last of the rear tire over the rim. Success again, tires mounted without the use of spoons. When inflating the tires there was on problem with getting the beads to seal either.
I am liking this machine the more I use it. The tips in their videos about using a ratchet strap to pull the beads into the valley of the rim work well. I'd still like to try the mount/dismount bar on the No-Mar but have to make a new pivot rod first. Another thing about the Tire Stripper is that adjusting the spacer blocks is very easy to do. Put them approximately where you thing they may go, put a tire on the machine, lift the tire slightly and slide the block into position and snug the wing-nut. No need to crank it down as it just supports the wheel. Storage space is another benefit of the Tire Stripper. The whole package will store into a 12" x 12" x 44" space, and that includes the vehicle mount bar.
More info as I lean it.
