Use screwdriver for removal.
CAUTION:
Be careful not to damage front cover.
12. Remove O-rings from cylinder heads (right and left bank) and cylinder block.

NOTE:
To remove timing chain and related parts, start with those on left bank. The procedure for removing parts
on right bank is omitted because it is the same as that for left bank.
a. Press tab in the direction of arrow (or turn lever in the direction of arrow) to unlock the locking with the groove that stops ten-
sioner plunger from returning.

Lightly press tensioner plunger to release the tension of
spring for this operation.
b. Push in tensioner plunger to align the hole on lever and that on pump main body.

Pushing in tensioner too far does not allow the holes to align.
Therefore, push in plunger to the degree at which the start of
stopper groove and tab engages.
c. Insert stopper pin [hard wire with approx. 0.5 mm (0.020 in) diameter or similar tool] to fix plunger. With plunger fixed, remove chain tensioner.
17. Remove chain tension guide and timing chain slack guide.
18. Remove timing chain and crankshaft sprocket.
CAUTION:
After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
the piston head.
19. With hexagonal part of camshaft locked with wrench, loosen mounting bolts securing camshaft sprocket to remove camshaft
sprocket.
CAUTION:
Do not loosen mounting bolts with securing anything other
than the camshaft hexagonal portion or with tensioning the
timing chain.
20. Perform same procedure as for left bank, remove timing chain and related parts on right side.
21. Use scraper to remove all traces of old liquid gasket from front cover and opposite mating surfaces.

Remove oil liquid gasket from bolt hole and thread.
22. Use scraper to remove all trace of liquid gasket from chain tensioner cover and intake valve timing control covers.

1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
2. Install camshaft sprockets.

Install onto correct side by checking with identification mark
on surface.

Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)

Lock the hexagonal part of camshaft in the same procedure
as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.

Install each crankshaft sprocket so that its flange side (the
larger diameter side without teeth) faces in the direction
shown in the figure.
NOTE:
The same parts are used but facing directions are different. Camshaft dowel pin
: At cylinder head upper face side in each bank
Crankshaft key : At cylinder head side of left bank

a. Install new O-rings onto cylinder heads (right and left bank) and
cylinder block.
b. Apply a continuous bead of liquid gasket with tube presser [SST: WS39930000 ( — )] to front cover as shown in the fig-
ure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
c. make sure again that the mating marks on timing chain and that on each sprocket are aligned. Then, install front cover.
CAUTION:
Be careful to avoid interference with the front end of oil
pump drive spacer. Such interference may damage front oil
seal.
d. Tighten mounting bolts in numerical order as shown in the fig- ure.

There are four type mounting bolts.
e. After all mounting bolts are tightened, retighten them in numerical order as shown in the figure. CAUTION:
Be sure to wipe off any excessive liquid gasket leaking onto surface mating with oil pan.
11. Install intake valve timing control cover as follows:
a. At the back of intake valve timing control cover, install new seal rings (three for each bank) to the area to be inserted into camshaft sprocket (INT).
CAUTION:
Do not spread seal ring excessively to avoid breaks and deformation.
