Valve head radial runout
Check each valve for radial runout with a dial gauge and
“V” block. To check runout, rotate valve slowly. If runout
exceeds its limit, replace valve.
Valve head radial runout
Limit: 0.08 mm (0.003 in.)
Seating contact width
Create contact pattern on each valve in the usual
manner, i.e., by giving uniform coat of marking
compound to valve seat and by rotatingly tapping seat
with valve head. Valve lapper (tool used in valve lapping)
must be used.
Pattern produced on seating face of valve must be a
continuous ring without any break, and the width of
pattern must be within specified range.
Standard seating width “a” revealed by contact
pattern on valve face
Intake and Exhaust: 1.0 – 1.4 mm (0.0389 – 0.0551
in.)Valve seat repair
A valve seat not producing a uniform contact with its
valve or showing width of seating contact that is out of
specified range must be repaired by regrinding or by
cutting and regrinding and finished by lapping.
1)Exhaust valve seat:
Use valve seat cutters (1) to make two cuts as
illustrated in figure. Two cutters must be used: the
first for making 22° angle, and the second for making
45° angle. The second cut must be made to produce
desired seat width.
Seat width for exhaust valve seat
“a”: 1.0 – 1.4 mm (0.0389 – 0.0551 in.)
2)Intake valve seat:
Use valve seat cutters (1) to make three cuts as
illustrated in figure. Three cutters must be used: the
1st for making 22° angle, the 2nd for making 60°
angle, and 3rd for making 45° angle. The 3rd cut
(45°) must be made to produce desired seat width.
Seat width for intake valve seat
“b”: 1.0 – 1.4 mm (0.0389 – 0.0551 in.)
3)Valve lapping:
Lap valve on seat in two steps, first with coarse size
lapping compound applied to face and the second
with fine-size compound, each time using valve
lapper according to usual lapping method.

Connecting Rod Bearing General Information
Service connecting rod bearings are available in
standard size and 0.25 mm (0.0098 in.) undersize
bearing, and standard size bearing has 5 kinds of
bearings differing in tolerance.
For identification of undersize bearing, it is painted red at
the position as indicated in figure, undersize bearing
thickness is 1.605 – 1.615 mm (0.0632 – 0.0635 in.) at
the center of it.
Connecting Rod Bearing Visual Inspection
Inspect bearing shells for signs of fusion, pitting, burn or
flaking and observe contact pattern. Bearing shells
found in defective condition must be replaced.
Connecting Rod Bearing Clearance
1) Before checking bearing clearance, clean bearing
and crank pin.
2) Install bearing in connecting rod and bearing cap.
3) Place a piece of gauging plastic (1) to full width of
crank pin as contacted by bearing (parallel to
crankshaft), avoiding oil hole.4) Install rod bearing cap (1) to connecting rod.
When installing cap, be sure to point arrow mark (2)
on cap to crankshaft pulley side, as shown in figure.
After applying engine oil to rod bolts, tighten cap nuts
(3) gradually as follows.
a) Tighten all cap nuts to 15 N⋅m (1.5 kgf-m, 11.0 lb-
ft)
b) Retighten them to 45°
c) Repeat Step b) once again.
Tightening torque
Connecting rod bearing cap nut (a): Tighten
15 N⋅m (1.5 kgf-m, 11.0 lb-ft) 45° and 45° by
the specified procedure
5) Remove cap and using a scale (1) on gauging
plastic envelope (2), measure gauging plastic (2)
width at the widest point (clearance).
If clearance exceed its limit, use a new standard size
bearing referring to “Selection of Connecting Rod
Bearings: ”.
After selecting new bearing, recheck clearance.
Connecting rod bearing clearance
Standard: 0.029 – 0.047 mm (0.0011 – 0.0018 in.)
Limit: 0.065 mm (0.0026 in.)
6) If clearance can not be brought to its limit even by
using a new standard size bearing, use next thicker
bearing and recheck clearance or regrind crank pin
to undersize and use 0.25 mm undersize bearing.

Main Bearings InspectionS6RW0D1406040
General Information
• Service main bearings are available in standard size
and 0.25 mm (0.0098 in.) undersize, and each of them
has 5 kinds of bearings differing in tolerance.
• Upper half of bearing (1) has oil groove (2) as shown
in figure.
Install this half with oil groove to cylinder block.
• Lower half of bearing does not have an oil groove.
Visual Inspection
Check bearings for pitting, scratches, wear or damage.
If any malcondition is found, replace both upper and
lower halves. Never replace either half without replacing
the other half.
Main Bearing Clearance
NOTE
Do not rotate crankshaft while gauging
plastic is installed.
Check clearance by using gauging plastic according to
the following procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.
3) Place a piece of gauging plastic (1) the full width of
bearing (parallel to crankshaft) on journal, avoiding
oil hole.4) Tighten main bearing cap No.1 bolts (1) – (10) and
main bearing cap No.2 bolts (11) – (20) gradually as
follows.
a) Tighten bolts (1) – (10) to 30 N⋅m (3.0 kgf-m,
22.0 lb-ft) according to numerical order in figure.
