 INSTALLATION

Note the following, and install in the reverse order of removal.
  • Check if the knock pins (2 each) of cylinder block and flywheel are not dropped, adjust the flywheel knock pin position so that it is inserted into the knock pin insertion hole (convex shape) () of drive line torsional vibration damper, and install them.
