INSTALLATION
1. When installing O-ring to fuel injector, follow instructions described below.
CAUTION:
●Handle O-ring with bare hands. Never wear gloves.
●Lubricate O-ring with new engine oil.
●Do not clean O-ring with solvent.
●Make sure that O-ring and its mating part are free of foreign material.
●Be careful not to scratch it with a tool or fingernails during installation. Also be careful not to
twist or stretch O-ring. If O-ring is stretched while being attached, do not insert it into fuel tube
immediately.
●Insert O-ring straight into fuel tube. Do not angle or twist it.
2.
Install fuel injector to fuel tube with the following procedure.
a. Insert clip into clip mounting groove on fuel injector.
●Insert clip so that lug “A” of fuel injector matches notch “A” of
the clip.
CAUTION:
●Do not reuse clip. Replace it with a new one.
●Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.
●Insert it while matching it to the axial center.
●Insert fuel injector so that lug “B” of fuel tube matches notch
“B” of the clip.
●Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel
injector does not rotate or come off.

to fuel piping.
2. Start engine, and re-check connections for fuel leakage by increasing engine speed. 1st step : 11.8 - 13.8 N·m (1.2 - 1.4 kg-m, 9 - 10 ft-lb)
2nd step : 17 - 23 N·m (1.7 - 2.4 kg-m, 13 - 17 ft-lb)

d. Referring to mating marks on intake and exhaust camshaft
sprockets, put paint mating marks on timing chain links.
4. Set intake camshaft sprocket to most advanced position.
CAUTION:
Removal/installation of intake camshaft sprocket is required to maintain most advanced position
because of following reasons. Therefore, follow procedure exactly.
●Sprocket and vane (camshaft in front) rotate and become
offset within specific angle range.
●When engine is stationary, vane is located at most
retarded position. Vane is fixed to sprocket by internal
lock pin. Therefore, it does not rotate.
●If camshaft sprocket mounting bolts are turned under
above circumstance, lock pin will be damaged by lateral
load (shear stress). It may cause non-standard operation.
●Set intake camshaft sprocket to most advanced position as
follows.
NOTE:
“Rotating direction” means direction viewed from engine front side.
CAUTION:
Do not remove chain tensioner before performing this step.
a. Using a wrench, hold hexagonal part so that intake camshaft
does not move.
b. Using an air gun, apply air pressure to intake valve timing con-
trol solenoid valve advanced side oil passage on top surface of
No. 1 camshaft bracket.
●Keep applying air pressure until step “d” is completed.
CAUTION:
●Be careful not to damage oil passage from interference of
air gun tip.
●Thoroughly wipe off oil before applying air pressure.
When applying air pressure, cover around air gun using a rag. Wear protective glasses if neces-
sary.

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.
