1. Make sure the crankshaft key and RH bank camshaft dowel pin
and LH bank camshaft dowel pin are facing in the direction
shown.
2. Install the camshaft sprockets. • Install the intake camshaft sprocket (A) and exhaust camshaftsprockets (B) by selectively us ing the groove of the dowel pin
according to the bank. (Common part used for both banks.)
• Lock the hexagonal part of the camshaft in the same way as for removal, and tighten the bolts.
• A = I : Intake
• B = V: Exhaust
3. Install the crankshaft sprockets for both banks. • Install LH bank crankshaft sprocket (B) and RH bank crank-shaft sprocket (C) so that their flange side (A) (the larger diam-
eter side without teeth) faces in the direction shown.
NOTE:
The same parts are used but facing directions are different.
4. Install the timing chains and associated parts. • Align the alignment mark on each sprocket and the timing chain for installation.
CAUTION:
• Before installing timing chain tensioner, it is possible to change the position of alignment mark
on timing chain and each sprocket . After the alignment marks are aligned, keep them aligned
by holding them by hand.
• Install the slack guides and tension guides onto the correct side by checking the identification mark on
the surface.
• Install the timing chain tensioner with the plunger locked in with the stopper pin.
CAUTION:
• Before and after the installation of the timing chain tensioner, make sure that the alignment
mark on the timing chain is not out of alignment.
• After installing the timing chain tensioner, remove the stopp er pin to release the tensioner.
Make sure the tensioner is released.
• To avoid chain-link skipping of the timing chain, do not move crankshaft or camshafts until the
front cover is installed.
5. In the same way as for the RH bank, install the timing chain and associated parts on the LH bank.
6. Install the oil pump.

TIMING CHAIN
a. Apply engine oil onto the threaded parts of the bolt and seating area.
b. Select the one most visible notch of the four on the bolt flange.Corresponding to the selected notch, put a alignment mark
(such as paint) on the crankshaft pulley.
14. Rotate the crankshaft pulley in normal direction (clockwise when viewed from engine front) to check for parts interference.
15. Installation of the remaining components is in the reverse of order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-12, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
