(b) Check that each timing mark of the camshaft timing gears
is aligned with each timing mark located on the No. 1 and
No. 2 bearing caps as shown in the illustration.
If not, turn the crankshaft 1 revolution (360) and align the
marks as above.
13. REMOVE CHAIN TENSIONER ASSY NO.1

NOTICE:
Be careful not to damage the cylinder head and valve lifter
with the wrench.
(b) Using several steps, loosen and remove the 10 camshaft
bearing cap bolts uniformly in the sequence shown in the
illustration.

15. REMOVE CAMSHAFT
(a) Using several steps, loosen and remove the 10 camshaft
bearing cap bolts uniformly in the sequence shown in the
illustration.
(b) Remove 5 camshaft bearings.
(c) Remove the camshaft.
(d) Tie the timing chain as shown in the illustration.
NOTICE:
Be careful not to drop anything inside the timing
chain cover.
Do not expose the chain to water, and prevents dust.
16. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise, and make sure the cam-
shaft timing gear does not rotate.
(b) Cover all the oil ports with vinyl tape except an advance
side port shown in the illustration.
(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm
2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the ports with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.

(a) Put the camshaft timing gear and the camshaft together
with the straight pin off the key groove.
(b) Turn the camshaft timing gear assembly to the left direc-
tion (as shown in the illustration) while lightly pushing it to-
ward the camshaft. Push further at the position where the
pin gets into the groove.
NOTICE:
Be sure not to turn the camshaft timing gear to the retard
angle side (to the right direction).
(c) Check that there is no clearance between the gear's
fringe and the camshaft.
(d) Tighten the fringe bolt with the camshaft timing gear fixed.
Torque: 54 Nm (551 kgfcm, 40 ftlbf)
(e) Check that the camshaft timing gear can move to the re-
tard angle side (to the right direction), and is locked at the
most retarded position.
18. INSTALL CAMSHAFT
(a) Turn the crankshaft pulley, and align its groove with timing
mark 0 of the timing chain cover.
(b) Install the timing chain on the camshaft timing gear, with
the painted links aligned with the timing marks on the
camshaft timing gear.
(c) Examine the front marks and numbers and tighten the
bolts in the order shown in the illustration.
Torque:
Bearing cap No. 1 30 Nm (301 kgfcm, 22 ftlbf)
Bearing cap No. 3 9.0 Nm (92 kgfcm, 80 in.lbf)
19. INSTALL NO.2 CAMSHAFT
(a) Put the No. 2 camshaft on the cylinder head with the
painted links of chain aligned with the timing mark on the
camshaft timing gear.
