(1) Apply engine oil to the thrust portion of the intakecamshaft.
(2) Lightly place the intake camshaft on top of the cylin-
der head as shown in the illustration so that the No.
1 and No. 4 cylinder cam lobes face downward.
(3) Lightly push the camshaft towards the front without
applying excessive force.
(4) Place the No. 2 and No. 5 bearing caps in their prop-
er location.
(5) Temporarily tighten these bearing cap bolts uni- formly and alternately in several passes until the
bearing caps are snug with the cylinder head.
(6) Place the No. 3, No. 4, No. 6 and No. 7 bearing caps
in their proper location.
(7) Temporarily tighten these bearing cap bolts, alter- nately tightening the left and right bolts uniformly.
(8) 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.
(9) Temporarily tighten the bearing cap bolts, alternate-
ly tightening the left and right bolts uniformly.
(10) Uniformly tighten the 14 bearing cap bolts in several
passes.
Torque: 16 N·m (160 kgf·cm, 12 ft·lbf)
(b) Install the exhaust camshaft. (1) Set the timing mark (2 dot marks) of the camshaftdrive gear at approx. 35 ° angle by turning the hexa-
gon wrench head portion of the intake camshaft
with a wrench.

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.

7. CHECK VALVE TIMING
(a) Turn the crankshaft pulley, and align its groove with the timing mark ”0” of the timing chain cover.
NOTICE:
Always turn the crankshaft clockwise.
(b) Check that the timing marks (1 and 2 dots) of the camshaft
drive and driven gears are in straight line on the cylinder
head surface as shown in the illustration.
If not, turn the crankshaft 1 revolution (360° ) and align the
marks as above.
8. CHECK AND ADJUST VALVE CLEARANCE (See page
EM−4)
Turn the camshaft and position the cam lobe upward and check
and adjust the valve clearance.

lybdenum disulpfide lithium base grease, NLGI No.2.
(h) Install the inner race in the cage through the large open-
ing.
(i) Position the protruding end of the inner race toward the wide side of the cage.
(j) Assemble the cage and inner race to the outer shaft by
fitting the 2 large openings in the cage against the pro-
truding parts of the outer shaft.
(k) Make sure to position the wide side of the cage and the inner race protruding end outward.
(l) Fit in the inner race and cage and install the 6 bearing balls in the outer shaft (See step (c)).
(m) Pack molybdenum disulpfide lithium base grease, NLGI No.2 in the outer shaft.
(n) Install a new snap ring on the inner shaft.
(o) Hold the outer shaft in a vise and while compressing the snap ring, install the inner shaft to the outer shaft.
(p) Make sure that the inner shaft cannot be pulled out.
