Canon EF 70-200mm f/4 L USM disassembly

This video is about disassembling the Canon EF 70-200mm f/4 L USM lens to remove the USM motor. I had a Canon 70-200mm f4 lens which had problems with the USM motor. The focusing did not work, and it was caused by a faulty USM motor. So I had to disassemble the lens, replace the USM motor with a new one, then assemble the lens. In this video I'll show you how to disassemble the lens to get access to the USM motor. If you're interested in the assembly video, then the link is in the description below.
