(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.

(a) Remove the 2 nuts, then remove the chain tensioner and a gasket.
NOTICE:
Do not turn the crankshaft.
9. REMOVE NO.2 CAMSHAFT
(a) Hold the No. 2 camshaft with a wrench on the hexagonal lobe, and loosen the camshaft timing gear set bolt.
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.
(c) Remove the 5 camshaft bearing caps.

(d) Raising the No. 2 camshaft, remove the set bolt.
(e) Remove the camshaft timing gear from the No. 2 cam-
shaft with the timing chain wrapped.
(f) Remove the camshaft timing gear from the timing chain.
10. 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 the 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.
11. REMOVE CAMSHAFT TIMING GEAR OR SPROCKET (LEADED GASOLINE)
(a) Clamp the camshaft in a vise and remove the bolt and the camshaft timing\
gear. 12. REMOVE CAMSHAFT TIMING GEAR ASSY(UNLEADED GASOLINE)
(a) Fix the camshaft with a vise, and make sure the camshaft
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/cm2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the paths 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.
(d) Remove the fringe bolt of camshaft timing gear.
NOTICE:

Be sure not to remove the other 4 bolts.

If reusing the camshaft timing gear, release the
straight pin lock first, and then install the gear.

14. INSTALL CAMSHAFT TIMING GEAR ASSY (UNLEADED GASOLINE)
(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 N
m (551 kgf
cm, 40 ft
lbf)
(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.
