(d) Remove the camshaft timing gear and chain from the in-
take camshaft and leave on the slipper and damper.
35. REMOVE CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the exhaust camshaft. (1) Bring the service bolt hole of the driven sub −gear
upward by turning the hexagon wrench head por-
tion of the exhaust camshaft with a wrench.
(2) Secure the exhaust camshaft sub −gear to the main
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 − 20 mm (0.63 − 0.79 in.)
HINT:
When removing the camshaft, make sure that the torsional
spring force of the sub −gear has been eliminated by the above
operation.
(3) Set the timing mark (2 dot marks) of the camshaftdriven gear at approx. 35 ° angle by turning the
hexagon wrench head portion of the intake cam-
shaft with a wrench.
(4) Lightly push the camshaft towards the rear without applying excessive force.
(5) Loosen and remove the No. 1 bearing cap bolts, al-
ternately loosening the left and right bolts uniformly.

(4) Loosen and remove the No. 3, No. 4, No. 6 and No.
7 bearing cap bolts, alternately loosening the left
and right bolts uniformly in several passes, in the
sequence shown.
NOTICE:
Do not remove the No. 2 and No. 5 bearing cap bolts at this
stage. (5) Remove the 4 bearing caps.
(6) Alternately and uniformly loosen and remove theNo. 2 and No. 5 bearing cap bolts.
HINT:
As the 4 No. 2 and No. 5 bearing cap bolts are loosened,
make sure that the camshaft is lifted out straight and level.
If the camshaft is not being lifted out straight and level, re-
tighten the 4 No. 2 and No. 5 bearing cap bolts. Then re-
verse the order of above steps from (e) to (c) and repeat
steps from (a) to (f) once again.
NOTICE:
Do not pry on or attempt to force the camshaft with a tool
or other object.
(7) Remove the 2 bearing caps and exhaust camshaft.
36. DISASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagon wrench head portion of the camshaft in a vise.
NOTICE:
Be careful not to damage the camshaft.
(b) Insert a service bolt (A) into the service hole of the cam-
shaft sub−gear.
(c) Using a screwdriver, turn the sub− gear clockwise, and re-
move the service bolt (B).
NOTICE:
Be careful not to damage the camshaft.
(d) Using snap ring pliers, remove the snap ring.

(7) Install and torque the 2 mounting bolts.
Torque: 21N·m (210 kgf·cm, 15 ft·lbf)
2. ASSEMBLE EXHAUST CAMSHAFT
(a) Mount the hexagon wrench head portion of the camshaft in a vise.
NOTICE:
Be careful not to damage the camshaft.
(b) Install the camshaft gear spring (1), camshaft sub −gear
(2) and wave washer (3).
HINT:
Align the pins on the gears with the spring ends.
(c) Using snap ring pliers, install the snap ring.
(d) Insert a service bolt (A) into the service hole of the cam- shaft sub−gear.
(e) Using a screwdriver, align the holes of the camshaft main
gear and sub− gear by turning camshaft sub − gear clock-
wise, and install a service bolt (B).
NOTICE:
Be careful not to damage the camshaft.
3. INSTALL CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being installed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.

camshaft.
(3) Engage the exhaust camshaft gear to the intake
camshaft gear by matching the timing marks (two
dot marks) on each gear.
(4) Roll down the exhaust camshaft onto the bearing journals while engaging gears with each other.
(5) Lightly push the intake camshaft towards the front without applying excessive force.
(6) Install the No. 4 and No. 6 bearing caps in their proper location.
(7) Temporarily tighten the bearing cap bolts uniformly and alternately in several passes until the bearing
caps are snug with the cylinder head.
(8) Place the No. 2, No. 3, No. 5 and No. 7 bearing caps
in their proper location.
(9) Temporarily tighten these bearing cap bolts, alter- nately tightening the left and right bolts uniformly.
(10) Place the No. 1 bearing cap in its proper location. When doing this, check that there is no gap be-
tween the cylinder head and the contact surface of
bearing cap.
(11) Temporarily tighten the bearing cap bolts, alternate-
ly tightening the left and right bolts uniformly.
(12) Uniformly tighten the 14 bearing cap bolts in several
passes.
Torque: 16 N·m (160 kgf·cm, 12 ft·lbf)
(13) Bring the service bolt installed in the driven sub −
gear upward by turning the hexagon wrench head
portion of the camshaft with a wrench.

tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge.
If necessary, adjust.
(b) Check for cuts, damage or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nut\
s.
If necessary, tighten them.
4. TIRE ROTATION
Check the owner’s manual supplement in which the maintenance schedule is shown.
