   *a	Paint Mark	*b	Timing Mark
   *c	"0" Timing Mark	-	-

   1. Turn the crankshaft clockwise to align the timing mark (cutout) on the crankshaft pulley assembly with the "0" timing mark on the No. 2 timing chain cover assembly.
   2. Check that the timing marks are positioned as shown in the illustration.
   3. If the timing marks are not positioned as shown in the illustration, turn the crankshaft clockwise and then align them again.
   4. Place paint marks on the chain sub-assembly at points aligned with the timing marks on the camshaft timing gear assembly and camshaft timing exhaust gear assembly.

   *a	Approximately 15°	*b	Pin
   *c	Pin Hole (No. 1 Chain Tensioner Assembly Side)	*d	Pin Hole (Chain Tensioner Slipper Side)
   *e	Hold	-	-
   	Turn	-	-

   1. Rotate the crankshaft approximately 15° clockwise.
   2. Rotate the crankshaft approximately 15° counterclockwise.
   3. Align the pin hole of the No. 1 chain tensioner assembly with the pin hole of the chain tensioner slipper, and then insert the pin.
   4. Using the hexagonal portion of the exhaust camshaft sub-assembly, secure the exhaust camshaft sub-assembly.
      NOTE:

      Do not damage the camshaft housing sub-assembly, cylinder head sub-assembly and spark plug tube.

   5. Remove the 2 bolts from the camshaft timing exhaust gear assembly.
   6. Using the hexagonal portion of the intake camshaft sub-assembly, secure the intake camshaft sub-assembly.
      NOTE:

      • Do not damage the camshaft housing sub-assembly, cylinder head sub-assembly and spark plug tube.
      • Do not disassemble the camshaft timing gear assembly.
   7. Using a 10 mm bi-hexagon socket wrench, remove the bolt from the camshaft timing gear assembly.

   1. Secure the chain sub-assembly to the vehicle using rope, etc.
      NOTE:

      Do not drop the chain sub-assembly into the timing chain cover assembly.

   2. Uniformly loosen and remove the 9 bolts in the order shown in the illustration.
   3. Uniformly loosen and remove the 13 bolts in the order shown in the illustration.
      NOTE:

      Uniformly loosen the bolts while holding the camshaft horizontally.

   4. Remove the No. 1 camshaft bearing cap, No. 2 camshaft bearing cap, 2 No. 3 camshaft bearing caps and No. 4 camshaft bearing cap.

      HINT:
