Pressure Plate Inside View

Inside View

View of the inside of the pressure plate with red arrows showing the eccentric position of the failed fulcrum ring.  To get this view, you have to take the pressure plate apart by cutting through the six sets of leaf springs located around the parameter of the assembly.  You can cut through them with an abrasive wheel on a hand grinder or a Portaband saw like I did.  The position of the failed fulcrum ring remains undisturbed. You will also expose the hidden pads and discs to inspect for any wear or warpage.  If the pressure plate assembly is as clean as this one, there will be no wear.  You might also see the original white ink identification stampings on the wear pads.  You can prove wear or no wear by measuring the thickness of the pads with a caliper.  If the pressure plated is coated with black residue, you will expect to see wear.  It'll take a few blades to cut the springs.  Keep track of your expenses, save your receipts.

To extract the fulcrum ring, You need to grind down all 18 rivets and punch them out.  Once you do this, you will also have released the residual stresses in the diaphragm and the diaphragm finger ends will all return to an equal height.
