 This is a 91-99 flywheel assembly but the process is basically comparable for 03 and prior flywheel assemblies. \\

+Use a 1-5/16" socket wrench to remove the crank pin nut on the sprocket side. \\
+With the crank nut off, lower the all-thread below the top wheel and retighten the nuts. \\
+You'll be knocking the top wheel sideways next to loosen it from the crank pin. \\

+Do not attempt to hit the hardened flywheel with a steel hammer alone. \\
+You need to use a soft metal hammer (brass, lead etc.) to keep from exploding the flywheel into your body parts. \\
+A sledge hammer hitting a block of aluminum against the wheel was used below (a rubber mallet will do you no good in this instance). \\
+Hit the top wheel 90º to the crank pin hole on the outside edge to knock it sideways and loosen itself from the crank pin taper. \\
+Basically hit the outside edge in the vicinity of the holding pin hole. The soft metal will not hurt the flywheel. \\

+It takes a pretty good whack to move it and swing it off to one side.\\
+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. \\
