I have the same problem with my 5665. One magnet still attached and the rest were stuck to the stator.
The Kohler K series service manual covers several models. For the K301 the flywheel torque is:
Hex nut - 50/60 ftlb.
Hex cap screw - 35/40 ftlb in one part of the manual and 22/27 ftlb in another part of the manual.
The crankshaft taper and flywheel hub are to be clean, dry, and free of lubricants. Threads are to be oiled.
