As a Certified TIA Commercial Instructor, I found it interesting that during the course, lots of questions came up about obsolete mulit-piece rims. It is really clear, if it is obsolete throw it out. It is a safety issue for not only your techicians but also your customers.
Download the attached PDF and keep it close when you are servicing these units and keep your technicians and customers safe. These are examples of where the identification stamps are.
If you have any questions on this, or what to learn more about being a TIA Certified Shop, please contact me.
