Installation Procedure

Important:  If replacing the engine flywheel (manual transmission), note the position and length of the original flywheel weights (if applicable). Flywheel weights of the same length must be installed into the new engine flywheel in the same location as the old flywheel weights were in the old engine flywheel.

1. Note the position of the flywheel weights and install the NEW flywheel weights as required.

   A properly installed flywheel weight will be flush or slightly below flush with the face of the engine flywheel.
