Canon EF 17-40mm f/4 L USM lens clean the USM motor focus sensor strip bar - repair focusing problem

This video is about disassembling the USM motor, cleaning the focus strip, then assembling the USM motor of a Canon EF 17-40mm f/4 L USM lens. The lens was hunting during focusing, and this was caused by a dirty focus strip. So I had to disassemble the USM motor, clean the focus strip then assemble the motor. To view how to remove the USM motor from the lens, see the "related videos" section below.
