Flywheel and Clutch

Here are pictures of the original flywheel that has been lightened on the inside and outside faces and rim equal to the amount if weight that was added to the counterweights on the crankshaft. 


Lightened flywheel.


This  equalizes the rotating mass so that it is distributed along the crankshaft length instead of just at the back end at the flywheel.  This keeps the flexing of the crankshaft to a minimum and eliminates beating the babbitt bearings out of the center main.  The outer ring that centered the A model pressure plate has been milled off and the flywheel drilled and tapped for the late model Ford v-8 and 9-n tractor pressure plate.  Mike and I found some of these at Wilson's tractor parts in Shelby.  

Late model pressure plate.

The one in the picture is brand new and I have two spares.  This clutch holds better and uses half the pedal pressure of the original A pressure plate.  Now that this is finished we will take the crankshaft, flywheel and pressure plate to be balanced.  I hope they will allow me to photograph the balancing process!  If not you can look it up on You Tube and see it done.
