FUEL INJECTOR AND FUEL TUBE
 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 stretc hed while it was being attached, do not insert it
quickly into fuel tube.
 Insert new O-ring straight into fuel tube. Do not decenter or twist it.
 Insert fuel damper and fuel sub- tube straight into fuel tube.
 Tighten mounting bolts evenly in turn.
 After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
2. Install new O-rings to fuel injector, paying attention to the following. CAUTION:
 Upper and lower O-ring 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 stretc hed while it was being attached, do not insert it
quickly into fuel tube.
 Insert O-ring straight into fuel in jector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip into clip mounting groove on fuel injector.  Insert clip so that protrusion “A ” of fuel injector matches cutout
“A” of 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 protrusion “B” of fuel tube matches
cutout “B” of clip.
 Make sure that fuel tube flange is securely fixed in flange fixing groove on clip.
c. Make sure that installation is complete by checking that fuel injector does not rotate or come off.
 Make sure that protrusions of fuel injectors are aligned withcutouts of clips after installation.
4. Install spacers on intake manifold.
5. Install fuel tube and fuel injector assembly to intake manifold. CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to
EC-87, "
Fuel Pressure Check".
3. Disconnect fuel pump fuse to avoid fuel injection during mea- surement.
4. Remove engine cover with power tool. Refer to EM-19, "
Component".
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-42, "
Component" and EM-43, "Com-
ponent".
6. Connect engine tachometer (not required in use of CONSULT-III).
7. Install compression gauge with an adapter (commercial service tool) onto spark plug hole.
 Use the adapter whose picking up end inserted to spark plughole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. Turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression
pressure and the engine rpm. Perform these steps to check each cylinder.
Compression pressure:
Unit: kPa (kg/cm2, psi) /rpm
CAUTION:
Always use a fully changed battery to obtain the specified engine speed.

HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft are Used:
1. “Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear upper side between cylinder block banks.
2. “Main Bearing Selection Table” columns correspond to main journal diameter grade on front side of crankshaft.
3. Select main bearing grade at the point where select ed row and column meat in “Main Bearing Selection
Table”.
CAUTION:
 Initial clearance for No. 1, 5 journal and No. 2, 3, 4 journal is different. Use two different selection
table for each part.
 No. 1, 5 journal and No. 2, 3, 4 journal have the same signs but different measures. Do not con-
fuse.
4. Apply sign at crossing in above step 3 to “Main Bearing Grade Table”. NOTE:
 “Main Bearing Grade Table” applies to all journals.
 Service parts is available as a set of both upper and lower.
When Cylinder Block and Crankshaft are Reused:
1. Measure the cylinder block main bearing housing inner diameter and the crankshaft main journal diame-
ter. Refer to EM-256, "
Inspection After Disassembly" and EM-256, "Inspection After Disassembly".
