repairing worn conveyor rollers
If your dollies wear down on one side such that the bolts on the wheels have lost their heads, you can take chain link fence tension bars (1/2" flat bar), weld them to the left over studs then back out the stud to replace the roller plastic.

- PS...you cut the tension bars into 2" long pieces and you use both ends of the bar to weld to the headless bolt.
There is a much more simple technice. Just Get an air activated hammer punch and an electric hand hel grinder with a cuttin wheel. Cut or grind what little is left of the head. Use the Hammer punch( air chisel) to punch out the bolt and replace. It saves hours and is much easier.
What brand roller it that?
I was referring to Sonnies...where the bolts are threaded into the axle.
You can usually still get an impact socket on the head... unless you really neglected your rollers (which I assume is what your reffering too). In that case tap it with a drill bit and get a back out tool. dragging out the welder it to much dam work! Hell, I keep a few dollys aside and just switch them out and work on the old one on a bench.
I've got a tracking problem at one wash that's wearing of one side. Don't know what's causing the problem. The drive sprocket is in line and the takeup sprocket is in line. But on the lower section I'm tracking to the inside.
When you've got a bunch of rollers to repair the welder method works faster.
Jimmy B. why not get a transit (you said you like equipment) or even cheaper a laser transit! set up at one end of your wash, and shoot down the tunnel to the other end. check alignment of each track section, also... check and see if they are plumb and level (same). If you claim that they are all in alignment, my monies is on you have a section or 2 that is leaning to starboard.
Jimmy J.
It was set up with a transit but you may be right. I did have one section that moved and I had to shift back in place.
