To reinstall the rubber hose securely, make sure of hose inser-
tion length and clamp orientation. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
SMA021D
Hose ClampingNJGI0001S0602If old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there
is a trace of tube bulging left on the old rubber hose, align
rubber hose at that position.
Discard old clamps; replace with new ones.
SMA022D
After installing leaf spring clamps, apply force to them in the
direction of the arrow, tightening rubber hose equally all
around.
PRECAUTIONS FOR ENGINE OILSNJGI0001S07Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
Health Protection PrecautionsNJGI0001S0701Avoid prolonged and repeated contact with oils, particularly
used engine oils.
Wear protective clothing, including impervious gloves where
practicable.
Do not put oily rags in pockets.
Avoid contaminating clothes, particularly underclothing, with
oil.
Heavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
First Aid treatment should be obtained immediately for open
cuts and wounds.
Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
Wash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.

may cause damage to the heated oxygen sensor, result-
ing in the MI coming on.
6. Remove exhaust manifold cover.
7. Loosen mounting nuts in reverse order shown in figure to
remove exhaust manifold and catalytic converter assembly.
INSPECTION AFTER REMOVAL
Surface Distortion
●Use a reliable straightedge and feeler gauge to check the flat-
ness of exhaust manifold fitting surface.
INSTALLATION
●Install in the reverse order of removal after this step.
●Tighten mounting nuts for exhaust manifold and catalytic con-
verter assembly in order shown in figure.
●Before installing exhaust manifold support, apply liquid gasket to
contact surface on engine side.

CAMSHAFT
c. Slowly turn intake camshaft in direction A (counterclockwise:
intake manifold side).
●Perform while applying air pressure.
CAUTION:
Be careful not to dislocate camshaft retaining spanner.
d. During above step, operating click (a sound indicating internal
lock pin is disengaged) is heard from inside of intake camshaft
sprocket. After hearing it, slowly turn intake camshaft in direction
B (clockwise: exhaust manifold side), and set to most advanced
position.
●Perform while applying air pressure.
●When vane rotates solely against sprocket, lock pin is disengaged even if operating click is not heard.
●If lock pin is not disengaged, apply vibration by jiggling the camshaft with a spanner.
●If lock pin is not disengaged with above step, hit intake camshaft in front by using plastic hammer.
e. The following status indicates that most advanced position is
achieved: vane starts rotating on its own, then sprocket also
starts rotating when camshaft is turned. When above status is
achieved, this step is complete.
●Most advanced position is confirmed when stopper pin groove
and lock pin breathing groove are aligned.
f. Stop air, insert stopper pin [approximately 3 mm (0.12 in) dia.,
length of inserted part is approximately 15 mm (0.59 in)] into
pinhole on camshaft sprocket to fix most advanced position.
NOTE:
In the figure, an Allen wrench [a/f 2.5 mm (0.091 in), short part:
approximately 20 mm (0.79 in), long part: approximately 50 mm
(1.97 in)] is used for stopper pin as an example.
CAUTION:
Load (spring reaction force) is not applied to stopper pin.
Pin is easily detached. Therefore, secure it with vinyl tape to
prevent detachment.
5. Remove chain tensioner.
●Remove in the following order.
a. Press plate down, and release stopper tab.
b. Insert plunger into tensioner body until it stops.
c. Secure plate by passing stopper pin (such as a hard wire)
through plate hole and body hole. (Plunger is also secured.)
d. Remove mounting bolts, and remove chain tensioner.

CAUTION:
Be sure to remove dowel pin.
NOTE:
●Dowel pins of crankshaft and signal plate are provided as a
set for each.
●If dowel pin is not available (when crankshaft and signal plate
are reused), use M6 bolt [length under head: 10 mm (0.39 in)
or longer] as its substitute.
6. Install the crankshaft to the cylinder block.
●While turning the crankshaft by hand, check that it turns smoothly.
7. Install main bearing cap.
●Main bearing cap is identified by identification paint No. made
on it before it is removed.
●Install it with arrow facing to front.
NOTE:
Main bearing cap cannot be replaced as a single part, because it
is machined together with cylinder block.
8. Tighten main bearing bolts in several steps in numerical order
shown in the figure.
●Apply engine oil onto thread and seat of mounting bolt.
●After tightening bolts to specified torque, make sure that
crankshaft rotates smoothly.
●Check crankshaft side clearance. Refer to EM-84, "CRANK-
SHAFT SIDE CLEARANCE" .
9. Install piston to connecting rod.
a. Using snap ring pliers, install snap ring to groove of piston rear side.
●Install with chamfered side facing piston pin side. Refer to EM-70, "Disassembly and Assembly" .
b. Install piston to connecting rod.
●Using hot-air blower, heat piston to 60 to 70°C (140 to 158°F) so that piston pin can be easily inserted
by hand. Insert piston pin into piston and connecting rod from front side of piston.
●Assemble so that front mark on piston head and oil hole in
connecting rod are positioned as shown in the figure.
c. Install snap ring to front side of piston.
●Refer to step “a” to install snap ring.
●After installation, make sure that connecting rod moves
smoothly.
