Removal and Installation
INFOID:0000000006628784
NOTE:
• To remove timing chain and associated parts, start with those on the LH bank. The procedure for removing
parts on the RH bank is omitted because it is the same as that for removal on the LH bank.
• To install timing chain and associated parts, start with those on the RH bank. The procedure for installing
parts on the LH bank is omitted because it is the same as that for installation on the RH bank.
REMOVAL
1. Remove the timing chain cover. Refer to
EM-48, "Removal and Installation"
.
2. Remove the oil pump drive spacer.
• Hold and remove the flat space of the oil pump drive spacer by
pulling it forward.
3. Remove the oil pump. Refer to
LU-14, "Removal and Installation"
4. Remove the chain tensioner on the LH bank using the following steps.
NOTE:
To remove the timing chain and associated parts, start with those on the LH bank. The procedure for

TIMING CHAIN
a. Squeeze the return-proof clip ends using suitable tool and push
the plunger into the tensioner body.
b. Secure the plunger using stopper pin.
• Stopper pin is made from hard wire approximately 1 mm (0.04
in) in diameter.
c.
Remove the bolts and chain tensioner.
WARNING:
Plunger, spring, and spring seat pop out when (squeezing)
return-proof clip without holding plunger head. It may
cause serious injuries. Always hold plunger head when
removing.
NOTE:
• Stop the plunger in the fully extended position by using the
return-proof clip (1) if the stopper pin is removed.
• Push the plunger (2) into the tensioner body while squeezing
the return-proof clip (1). Secure it using stopper pin (3).
5. Remove the timing chain tension guide and timing chain slack guide.
6. Remove the timing chain and crankshaft sprocket.
7. Loosen the camshaft sprocket bolts as shown and remove the
camshaft sprocket.
CAUTION:
To avoid interference between valves and pistons, do not
turn crankshaft or camshaft when timing chain is discon-
nected.
8. Repeat the same procedure to remove the RH timing chain and
associated parts.
INSPECTION AFTER REMOVAL
Check for cracks and any excessive wear at link plates. Replace
chain if necessary.
• In the same way as for the LH bank, inspect the timing chain and
associated parts on the RH bank.

NOTE:
• The illustration above shows the relationship between the mating mark on each timing chain and that of the
corresponding sprocket, with the components installed.
• To install the timing chain and associated parts, start with those on the RH bank. The procedure for installing
parts on the LH bank is omitted because it is the same as that for installation on the RH bank.
1. Make sure the crankshaft key and RH bank camshaft dowel pin
and LH bank camshaft dowel pin are facing in the direction
shown.

TIMING CHAIN
2. Install the camshaft sprockets.
• Install the camshaft sprocket INT (VTC) (A) and camshaft
sprockets EXH (B) by selectively using the groove of the
dowel pin according to the bank. (Common part used for both
exhaust banks.)
NOTE:
Use the groove marked "R" for RH bank and "L" for LH bank.
• Lock the hexagonal part of the camshaft in the same way as
for removal, and tighten the bolts.
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 stopper 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.
7. Install the oil pump drive spacer as follows:
• Install so that the front mark on the front edge of the oil pump
drive spacer faces the front of the engine.
• Insert the oil pump drive spacer according to the directions of
the crankshaft key and the two flat surfaces of the oil pump
inner rotor.
• If the positional relationship does not allow the insertion, rotate
the oil pump inner rotor to allow the oil pump drive spacer to
be inserted.
