Shop update. Finally finished up refurbishing the tire machine! Note I didn't repaint the whole machine, just a few select things and a decent cleaning. A rundown of the items repaired:
I have replaced all the air lines, as they were replaced before with SAE tubing, and were brittle and misrouted. The air lines on this are 8mm, 10mm, and 12mm, all used in different spots. This is important because the push lock fittings were all leaking from the incorrect OD tubing being used. I had to replace a majority of the push lock fittings as well from this issue.
The rim clamps have all been blasted, painted, and lubed for free operation. I also cup wire wheeled the table and wiped down with WD40 to protect it from rust.
I order pre coiled tubing for the tire inflator nozzles. I tried to coil my own tubing, but filed miserably. Strait hose (like was there) were just dragging the machine while the table spun an was distressing the fittings.
The rim clamp cylinders were leaking at the cylinder end caps and air line banjo fittings. So, I disassembled the cylinders, cleaned them, replaced the end cap O-rings, and used new nylon/plastic seals on the air line banjo fittings.
The foot pedal air valves were leaking, this was caused by stripped out threads where the push lock fittings thread into. Likely caused by the person who haphazardly replaced the air lines previously. I sourced these from amazon fairly easily.
The pedal cover plate was blasted, repainted, and a new decal was applied.
The overpressure relief valve on the tank was leaking, this just required a good cleaning to get the O-ring to seal again. I also replaced the tank gauge with a fresh one for my older eyes.
The air pressure regulator, dryer, and oiler was leaking pretty much everywhere, so I bought a more compact replacement and installed it with a better mounting tab, the original mounting was janky.
I purchased a new lube bucket, and fabricated a mounting bracket to keep it in place.
The inflator gauge housing was plastic, destroyed, and the gauge was barely legible. So, I bought a larger gauge for a Coats machine, and fabricated a new steel box to house it. While I was there, I replaced the inflator hose with a better quality hose.
I also re-tapped the side cover threads as the holes were stripped out.
I had to straiten out the feet to keep the machine firmly planted on the floor and get rid of the rocking it used to have.
Lastly, but not all installed yet, are nylon/plastic rim savers. These are placed on the rim clams, the duck head, and the bead breaker (already installed).
A few pics, I still need to do some final cleaning:
This machine will get USED, and is a great addition to my shop! Now, to get a wheel balancer! I am pleased with the purchase, as they are fetching 1K plus used depending on the shape, and I have $600 all in on this machine. I also have the piece of mind knowing this is effectively a mechanically new machine, and should last my lifetime.
