  1. Position clutch disc with damper springs toward transmission and side marked "Flywheel Side" toward flywheel. Use clutch aligner to support and center clutch disc.
  2. Position pressure plate on flywheel. Using a crisscross sequence, tighten pressure plate attaching bolts gradually and evenly to prevent distortion. Remove clutch aligner. Apply a light coat of graphite grease to ball socket, fork fingers at release bearing end, inside of release bearing collar and clutch fork groove.
  3. To complete installation, reverse removal procedure. Torque all bolts to specification. Check system for proper operation.
