6. After all bolts are tightened, retighten them to the specified torque in numerical order as shown below.
   • If liquid gasket protrudes, wipe it off immediately.
7. After installing rear timing chain case, check the surface height difference between following parts on oil pan (upper) mounting surface.

   Standard 

   Rear timing chain case to lower cylinder block: 

   -0.24 to 0.14 mm (-0.0094 to 0.0055 in) 

   • If not within the standard, repeat the installation procedure.

2. Install timing chains (secondary) and camshaft sprockets (INT and EXH).
   • Align the mating marks on timing chain (secondary) (copper color link) with the ones on camshaft sprockets (INT and EXH) (punched), and install them.
   NOTE:

   • Mating marks for camshaft sprocket (INT) are on the back side of camshaft sprocket (secondary).
   • There are two types of mating marks, circle and oval types. They should be used for the right and left banks, respectively.
   Fig 9: Aligning Timing Chain Mating Marks With Ones On Camshaft Sprockets

   Right bank : Use circle type. 

   Left bank : Use oval type. 

   • Align dowel pin and pin hole on camshafts with the groove and dowel pin on sprockets, and install them.
   • the camshaft front end with dowel pin on the back side of camshaft sprocket, and install them.
   • On the exhaust side, align dowel pin on camshaft front end with pin groove on camshaft sprocket, and install them.
   • In case that positions of each mating mark and each dowel pin do not fit on mating parts, make fine adjustment to the position holding the hexagonal portion on camshaft with wrench or equivalent.
   • Bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is enough to prevent the dislocation of dowel pins.
   • It may be difficult to visually check the dislocation of mating marks during and after installation. To make the matching easier, make a mating mark on the top of sprocket teeth and its extended line in advance with paint.

3. After confirming the mating marks are aligned, tighten camshaft sprocket bolts.
   • Secure camshaft using wrench at the hexagonal portion to tighten bolts.

1. Install crankshaft sprocket.
   • Make sure the mating marks on crankshaft sprocket face the front of engine.

2. Install the primary timing chain.
   • Water pump (G).
   • Install primary timing chain so the mating mark punched (B) on camshaft sprocket is aligned with the blue link (A) on the timing chain, while the mating mark notched (E) on the crankshaft sprocket (D) is aligned with the copper link (F) on the timing chain, as shown below.
   • When it is difficult to align mating marks (A) with (B) and (E) with (F) of the primary timing chain with each sprocket, gradually turn the camshaft using a wrench on the hexagonal portion to align it with the mating marks.
   • During alignment, be careful to prevent dislocation of mating mark alignments of the secondary timing chains.

• When installing timing chain tensioner (primary), push in plunger and keep it pressed in with stopper pin.
• Remove any dirt and foreign materials completely from the back and the mounting surfaces of timing chain tensioner (primary).
• After installation, pull out stopper pin.

• Apply new engine oil to both oil seal lip and dust seal lip.
• Install it so that each seal lip is oriented as shown below.
