      *a	Protrusion (for position alignment)
      *b	Protrusion (for stopper)
      *c	Cutout

   2. Insert the tail exhaust pipe baffle sub-assembly to the position where it can be pressed in by hand.
   3. Using a plastic-faced hammer and wooden block, uniformly tap the tail exhaust pipe baffle sub-assembly onto the tail exhaust pipe assembly.
      NOTE:

      • Lightly tap the top and bottom of the tail exhaust pipe baffle sub-assembly so that the tail exhaust pipe baffle sub-assembly is pressed in without a tilt.
      • Press the tail exhaust pipe baffle sub-assembly in until the protrusion on the tail exhaust pipe assembly is fit into the cutout area of the tail exhaust pipe baffle sub-assembly.
      • Check that there is no looseness in the tail exhaust pipe baffle sub-assembly.
