Yes, a simple fix assuming it's similar to the DC07/14: remove soleplate and brushroll, then the brushroll holder. Remove the clutch cover (3 screws). Unhook belt from motor spindle and the clutch then just pulls out (needs a good tug sometimes). Reverse sequence to replace.
The job is a lot easier with a belt removal tool, though not essential. You'll otherwise just need a T15 Torx driver.
