5. Remove intake valve timing control cover as follows:
a. Loosen and remove mounting bolts in the reverse order as shown in the figure.
b . U s e s e a l c u t t e r [ S S T: K V 1 0 1111 0 0 ( J 3 7 2 2 8 ) ] t o c u t l i q u i d g a s k e t for removal.
CAUTION:

Exercise care not to damage mating surfaces.

Pull out cover keeping levelness without an angle, as
inner part of cover is engaged with the center of camshaft
sprocket (INT).
6. Remove O-rings from front cover.
7. Obtain No. 1 cylinder at TDC of its compression stroke as follows:
a. Rotate crankshaft pulley clockwise to align the TDC identifica- tion notch (without paint mark) with timing indicator on front
cover.
b. Make sure that both intake and exhaust cam noses of No. 1 cyl- inder (engine front side of left bank) are located as shown in the
figure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

a. Remove rear plate cover, and set ring gear stopper (SST).
b. Loosen crankshaft pulley bolt, and then pull crankshaft pulley with both hands to remove it.
CAUTION:

Do not remove crankshaft pulley bolt. Keep loosened
crankshaft pulley bolt in place to protect removed crank-
shaft pulley from dropping.

Do not remove balance weight (inner hexagon bolt) at the
front of crankshaft pulley.
9. Remove oil pan and oil strainer. Refer to EM-187, "
OIL PAN AND OIL STRAINER" .
10. Remove front cover as follows:
a. Loosen mounting bolts in reverse order as shown in the figure.
b . U s e s e a l c u t t e r [ S S T: K V 1 0 1111 0 0 ( J 3 7 2 2 8 ) ] t o c u t l i q u i d g a s k e t for removal.
CAUTION:

Exercise care not to damage mating surfaces.

After removal, handle front cover carefully so it does not
tilt, cant, or warp under a load.
11. Remove front oil seal from front cover using suitable tool.

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.
13. Remove chain tensioner cover from front cover.

Use seal cutter [SST: KV10111100 (J37228)] to cut liquid gasket for remove.
14. Remove oil pump drive spacer.

Set bolts in the two bolt holes [M6 × pitch 1.0 mm (0.04 in)] on
front surface. Using suitable puller, pull oil pump drive spacer
off from crankshaft.
NOTE:
The dimension between the centers of the two bolt holes is 33
mm (1.30 in).
In the figure, a commercial steering puller is used.
15. Remove oil pump. Refer to LU-31, "
OIL PUMP" .
16. Remove chain tensioner (left bank) as follows:

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.
