Hi all,



I'm trying something with Google photos where you can share multiple images with a link and I want to see if this works.



We had to have Mycronic (Mydata) come in for our MY19 as we had something going on with the motion. Our technician here noticed metal particles in the bearing lubrication of the head which ain't good. The machine has

60,000 hours power on time, so it's been around awhile.



Got the drive belt off and then started looking at things, we were shocked and at the same time grateful for what we discovered. The toothed roller on the left hand side of the drive was full of radial cracks and was close to coming apart and no telling what would have happened if it did. The Mycronic field service engineer said he's never seen anything like it and he's been with them in excess of 25-years. Said belt replacements occur somewhere between 30,000 - 50,000 hours, but he's never seen a roller crack like this:
