 +At this point, you can lift the top wheel off the assembly. \\ 
 + 
 +**Note**: Use a short piece of pipe (O.D. no bigger than the bearing cage) over the crank pin and against the top bearing cage. \\ 
 +(else the small bearings will fall out and scatter when you pull the rods up) \\ 
 +That was not done here and bearings did scatter. \\ 
 +Then remove the connecting rods. \\

 +The bearings and parts will go everywhere so it's best to have a storage container of sorts to keep them in until you're ready for reassembly. \\

 +Next, the jig has to be drilled to accept the crank pin and allow the bottom flywheel to sit over the holding pins. \\ 
 +The wheel was placed over the pins, leveled and the crank pin location outlined. \\

 +Then another 2" hole was made into the outline for the crank pin. \\
 +Lower the wheel into position and the nut can now be removed with the 1-5/16" socket. \\

 +Then, knock the pin out with punch and hammer (make sure there is something soft under the crank pin for it to land on). \\
 +Again, it'll take a good whack to dislodge the crank pin. \\
