8. Loosen mounting bolts in reverse order as shown in the figure.
9. Remove fuel tube protector.
10. Pull out fuel tube and fuel injector assembly rearward of engine.
CAUTION:

When removing, be careful to avoid any interference with fuel injector.

Use a shop cloth to absorb any fuel leaks from fuel tube.
11. Remove fuel injector from fuel tube with the following procedure:
a. Open and remove clip.
b. Remove fuel injector from fuel tube by pulling straight.
CAUTION:

Be careful with remaining fuel that may go out from fuel
tube.

Be careful not to damage fuel injector nozzle during
removal.

Do not bump or drop fuel injector.

Do not disassemble fuel injector.
INSTALLATION
1. Note the following, and install O-rings to fuel injector.
CAUTION:

Upper and lower O-rings are different. Be careful not to confuse them.

Handle O-ring with bare hands. Do not 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.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert O-ring straight into fuel tube. Do not decenter or twist it.

Insert until you hear a “click” sound and actually feel the engagement.

To avoid misidentification of engagement with a similar sound, be sure to perform the next
step.
c. Before clamping fuel feed hose with hose clamps, pull quick connector hard by hand holding “A” position.
Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
d. Install quick connector cap to quick connector connection. (On
both the engine side and the vehicle side)

Install so that the arrow mark on the side faces up.
CAUTION:

Make sure that quick connector and fuel tube are
securely fit into quick connector cap installation groove.

If quick connector cap cannot be installed smoothly,
quick connector may have not been installed correctly.
Check connection again.
NOTE:
There is quick connector cap for the engine side and for the
vehicle side, and they have different shapes. The figure shows engine side as an example.
8. Install fuel feed hose to hose clamp.
9. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then make sure
there are no fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
2. Start engine. With engine speed increased, make sure again there are no fuel leaks at connections.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.

CAUTION:
Be careful not to drop mounting bolts inside front cover.
NOTE:
Use approximately 0.5 mm (0.02 in) dia. hard metal pin as a
stopper pin.
c. Secure hexagonal part of camshaft with wrench. Loosen cam-
shaft sprocket mounting bolts and remove camshaft sprockets.
CAUTION:

Do not loosen mounting bolts with securing anything
other than the camshaft hexagonal part or with tension-
ing timing chain.

Do not rotate crankshaft or camshaft while timing chain
is removed. It causes interference between valve and pis-
ton.
NOTE:
Chain tension holding work is not necessary. Crankshaft
sprocket and timing chain do not disconnect structurally while
front cover is attached.
9. Remove camshaft position sensor (PHASE) from cylinder head back side.
CAUTION:

Handle carefully to avoid dropping and shocks.

Do not disassemble.

Do not allow metal powder to adhere to magnetic part at sensor tip.

Thickness of new valve lifter can be identified by stamp mark
on the reverse side (inside the cylinder).
Stamp mark “696” indicates 6.96 mm (0.2740 in) in thickness.
NOTE:
Available thickness of valve lifter: 26 sizes range 6.96 to 7.46 mm (0.2740 to 0.2937 in) in steps of 0.02
mm (0.0008 in) (when manufactured at factory). Refer to EM-110, "
Available Valve Lifter" .
5. Install the selected valve lifter.
6. Install camshaft. Refer to EM-47, "
INSTALLATION" .
7. Manually rotate crankshaft pulley a few rotations.
8. Make sure that valve clearances for cold engine are within specifications by referring to the specified val-
ues. Refer to EM-50, "
INSPECTION" .
9. Install all removed parts in the reverse order of removal. Refer to EM-47, "
INSTALLATION" .
10. Warm up the engine, and check for unusual noise and vibration.
