1(2) Tighten the bearing caps in the order shown two to
three times by torquing progressively.
Tighten to specification in the final sequence.
(3) Check to be sure that the rocker arm is correctly placedon the lash adjuster and valve stem end.
5. INSTALLATION OF CAMSHAFT OIL SEAL
(1) Install the special tool, Guide, on the camshaft.
(2) Apply oil to the oil seal and insert the seal along the
Guide until it contacts the cylinder head.
(3) Using the special tool, Installer, press-fit the oil seal intothe cylinder head.
2. INSTALLATION OF CAMSHAFT SPROCKET
Using a wrench hold the camshaft at its hexagon (betweenthe
No.2 and No.3 journals) and tighten the bolt to
specification.Caution
Locking the camshaft sprocket with a tool damages the
sprocket.1. INSTALLATION OF CRANK ANGLE SENSOR
(1) Locate the dowel pin on the sprocket side of the intake
camshaft at top.
(2) Align the punch mark on the crank angle sensor housingwith the notch in plate.
NOTE
The crank angle sensor can be installed even when thepunch mark is positioned opposite the notch; however,
the position results in incorrect fuel injection and
ignition timings.
(3) Install the crank angle sensor on the cylinder head.

N14FGAE
MD998709

IFUO157Make the following operations to release the pressure remain-
ing in fuel pipe line so that fuel will not flow out.
(1) Disconnect the fuel pump harness connector at the fuel
tank rear side.
(2) Start the engine and after it stops by itself, turn the ignition
switch to OFF.
(3) Disconnect the battery
(-) terminal.
(4) Connect the fuel pump harness connector.
FUEL PUMP OPERATION CHECK
Nl4FDAG(1) Set the ignition switch at OFF.
(2) Check that when the batten/ voltage is directly applied to
the fuel pump check terminal, the operating sound of the
pump can be heard.
NOTESince the fuel pump is installed in the fuel tank, its
operating sound cannot be readily heard. Remove the fuel
tank cap and listen to the operating sound through the filler
port.(3) Hold the high pressure fuel hose between your fingers and
check that the fuel pressure can be felt.
FUEL PRESSURE TEST
Nl4FNAN(1) Reduce the fuel pressure in the fuel line.
(2) Disconnect the high pressure fuel hose from the delivery
pipe.
CautionCover the hose connection with shop towel to prevent
splash of fuel that could be caused by residual pressurein the fuel pipe line.
(3) Connect a fuel pressure gauge to the special tool (hose
adapter).Use a suitable O-ring or gasket between the fuel pressure
gauge and the special tool so as to seal in order to preventfuel leakage at this time.

FUEL SYSTEM - Service Adjustment Procedures <2.0L Engine>14-51THROTTLE BODY (THROTTLE VALVE AREA)
CLEANINGNl4FtU
(1) Warm up the engine, then stop it.
(2) Remove the air intake hose from the throttle body.
(3) Plug the bypass passage inlet of the throttle body.
CautionDo not allow cleaning solvent to enter the bypass
passage.(4) Spray cleaning solvent into the valve through the throttle
body intake port and leave it for about 5 minutes.
(5) Start the engine, race it several times and idle it for about 1minute. If the idling speed becomes unstable (or if the
engine stalls), slightly open the throttle valve to keep the
engine running.
(6) If the throttle valve deposits are not removed, repeat steps
(4) and (5).
(7) Unplug the bypass passage inlet.
(8) Attach the air intake hose.
(9) Disconnect the battery terminal for 10 seconds or more,
and then reconnect it.
(lO)Adjust the basic idle speed. (Refer to P.14-48.)

H;OSECaution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
INSPECTIONN14GCAll Check the hoses and the pipes for crack or damage.
l Check the fuel tank cap for malfunction.
l Check the fuel tank for deformation, corrosion or crack.
0,. Check the fuel tank for dust or foreign material.
NOTE
If the inside of the fuel tank is to be cleaned, use any one ofthe following:
(1) Kerosene
(2)
Trichloroethylene-(3) A neutral emulsion type detergent
OVERFILL LIMITER (TWO-WAY VALVE)
Set a hand vacuum pump at inlet side or outlet side; the valve
is good if, when a negative pressure (vacuum) is applied, air
flows after a slight negative pressure is initially maintained.
SERVICE POINTS OF INSTALLATION.
Nl4DDAL15. INSTALLATION OF ELECTRICAL FUEL PUMP
(1) Align the three positioning projections of the packing
with the holes in the fuel pump.
(2) When the fuel pump is installed, the holding bolt at the
lower side of the fuel tank should be installed first.
Care should be taken at this time that the O-ring is not
pinched.14. INSTALLATION OF FUEL GAUGE UNIT
Align the two positioning projections of the packing with
the holes in the fuel gauge unit.
Caution
When mounting the fuel gauge unit, incline the float at
the end leftward, and insert it into the fuel tank. Since
the reserver cap is provided in the fuel tank, the fuel
gauge unit will contact the reserver cap if the fuel
gauge unit is inclined rightward during insertion.
