Pottery wheel belts in Equipment Use and Repair Posted July 15, 2018 · Report reply Hello Marcia, I have a similar question because I need a belt for a CXC. So we can use belts from auto supply stores? I have a used CXE that needs a new belt. I called one clay pottery supplier place and they said it might need to be ordered directly from Amoco and that I should call back on another day when their customer service person who knows about belts is there. I went to the Brent webpage and found out what size I need. I know it’s a six groove V belt. The belts at the auto store looks totally different from the ones in the Brent video so I know that the auto people call their v groove belt s serpentine. I just wasn’t sure I could use a non-Brent belt.
