Yes clutch and magnet have to come off. But its super easy, run center bolt of clutch out, then you run a course thread 5/8 bolt into existing threads in center of clutch hub. That 5/8 bolt pushes clutch off of shaft as you tighten it. So basically the 5/8 threads which are visible after that bolt in center is removed is like a built in clutch puller. Super easy. Then clutch magnet is three small bolts. Its about the easiest compressor clutch on planet earth to remove.
