Had to remove the prop to put some nutplates in. The 2-1/4" prop extension would not come of to take the rear f so had to set the prop on some wood blocks and hammered the pins with a brass rod and a heavy hammer taping each pin untill it came off with the S-602-1 rear spinner bulk head would come off, this is the way the Sensenich support said to do it and it did come off.
