Pretty straight forward, take cover off, remove nut and washer, screw the puller (counterclockwise) then using your impact gun give a couple blips it will come right off!
Be careful you don't loose the woodruff key (half moon shape), it goes back on the crank with the rounded side down!
If the woodruff key is damaged at all use a new on. It will save ya a headache in the end!
