A rattling sound, apparently originating in the clutch, may be caused if the clutch-pedal pull-back spring is disconnected. Connect the spring, and check to see if the rattling is eliminated.
 If rattling continues it may due to weak pressure-plate retracting springs or excessive clearance between driving lugs and cover. The clutch assembly must be replaced.
