+ | This is a 91-99 flywheel assembly but the process is basically comparable for 03 and prior flywheel assemblies. \\ | ||
+ | The table is a 3/4" piece of plywood hinged to the wall with a 2x4 stood up under it. \\ | ||
+ | To make it easier, no measuring of the holes was done. \\ | ||
+ | |||
+ | A 2" hole saw was used to bore a hole for the pinion shaft to sit down in. | ||
+ | The size of the hole isn't really critical as long as it's bigger than the shaft. \\ | ||
+ | The 2" hole just gives some leeway to position the wheels to drill for the holding pins. \\ | ||
+ | |||
+ | Then a 3/8" drill bit was run into the holes to the board to mark the hole locations. \\ | ||

+ | The location can be adjusted if needed before drilling the holes. \\ | ||
+ | Once the holes are drilled, run 2 pieces of 3/8" x 12" threaded rod into the holes with nuts and washers on top and bottom. \\ | ||
+ | Make sure they're tall enough to go through the holes in the top wheel. \\ | ||
+ | Then set the wheel over the all-thread (or holding pins). \\ | ||

+ | 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. \\ | ||
+ | It takes a pretty good whack to move it and swing it off to one side. The soft metal will not hurt the flywheel. \\ | ||
