Nipped down to these chaps Precision Clutch Components for them to have a look at my pressure plate and friction plate. They tested the pressure plate on their special press and showed me it was all working fine and lifting as it should. No cracks or signs of too much wear. The friction plate, however, told another story. Apart from being worn down near to the rivets it was evident that there is a groove in the flywheel which will need to be sorted before a new friction plate is put back on. So, the next mission is to source another flywheel or have the current one repaired or re-faced.
