FUEL INJECTOR AND FUEL TUBE
Removal and InstallationINFOID:0000000001538819
CAUTION:
Do not remove or disassemble parts unless instructed as shown.
REMOVAL
1. Remove engine room cover using power tool. Refer to EM-24, "Removal and Installation".
2. Release fuel pressure. Refer to EC-494, "
Fuel Pressure Check".
3. Disconnect the negative battery terminal.
4. Disconnect fuel injector harness connectors.
5. Disconnect fuel hose assembly from fuel tube (RH bank and LH bank). CAUTION:
• While hoses are disconnected, plug th em to prevent fuel from draining.
• Do not separate fuel co nnector and fuel hose.
6. Remove fuel injectors with fuel tube assembly.

7. Remove fuel injector from fuel tube.
a. Spread open to remove clip.
b. Remove fuel injector from the
fuel tube by pulling straight out.
CAUTION:
• Be careful with remaining fuel that may leak out from fuel
tube.
• Do not damage injector nozzles during removal.
• Do not bump or drop fuel injectors.
• Do not disassemble fuel injectors.
8. Remove fuel damper from each fuel tube.
INSTALLATION
1. Install fuel damper to each fuel tube.
a. Apply engine oil to O-ring and set it into the cap of fuel tube. 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 for- eign material.
• When installing O-ring, be car eful not to scratch it with
tool or fingernails. Also be careful not to twist or stretch
O-ring.
b. Make sure that backup spacer is in the O-ring connecting sur- face of fuel damper.
NOTE:
Backup spacer is fuel damper assembly part.
c. Insert fuel damper until it seats on fuel tube. CAUTION:
• Insert straight, making sure that the axis is lined up.
• Do not pressure-fit with excessive force.
d. Install cap, and then tighten bolts evenly by turns. • After tightening bolts, make sure that there is no gap between cap and fuel tube.
2. Install O-rings to fuel injector paying attention to the items below. CAUTION:
• Upper and lower O-ring are different.
• Handle O-ring with bare hands. Never wear gloves.

TIMING CHAIN
Check for cracks and any excessive wear at link plates. Replace
chain if necessary.
• In the same way as for the LH bank, inspect the timing chain andassociated parts on the RH bank.
INSTALLATION
NOTE:
• The above figure shows the relationship between the ma ting mark on each timing chain and that of the cor-
responding sprocket, with the components installed.
• To install the timing chain and associated parts, start with those on the RH bank. The procedure for installing parts on the LH bank is omitted because it is t he same as that for installation on the RH bank.

5. Press the valve guide from the camshaft side to the dimensions
as shown.
CAUTION:
Cylinder head contains heat . When working, wear protec-
tive equipment to avo id getting burned.
6. Ream the cylinder head valve guide using suitable tool.
VALVE SEAT CONTACT
• After confirming that the dimensions of the valve guides and valves are within specifications, perform this procedure.
• Apply prussian blue (or white lead) onto the contacting surface of the valve seat to check the condition of the valve contact on the
surface.
• Check if the contact area band is continuous all around the circum- ference.
• If not, grind to adjust the valve fi t and check again. If the contacting
surface still has NG conditions even after the re-check, replace the
valve seat.
VALVE SEAT REPLACEMENT
When the valve seat is removed, replace it with oversized (0.5 mm, 0.020 in) valve seat.
1. Bore out the old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess in the cylinder head. Set the machine depth stop to ensure this.
2. Ream the cylinder head recess diameter for service valve seat.
• Be sure to ream in circles concentric to the valve guide center.
• This will enable valve seat to fit correctly.

Use Undersize Bearing Usage Guide
• Use undersize (US) bearing when the oil clearance with
standard size main bearing is not within specifica-
tion.
• When using undersize (US) bearing, measure the inside di ameter of the bearing installed and grind the jour-
nal until the oil clearance falls within specification.
