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.

Installation
1) Apply engine oil to pistons, rings, cylinder walls,
connecting rod bearings and crank pins.
NOTE
Do not apply oil between connecting rod and
bearing or between bearing cap and bearing.

2) Install guide hoses (1) over connecting rod bolts.
These guide hoses protect crank pin and threads of
rod bolt from damage during installation of
connecting rod and piston assembly.
3) When installing piston and connecting rod assembly
into cylinder bore, point front mark (1) on piston head
to crankshaft pulley side.4) Install piston and connecting rod assembly into
cylinder bore. Use special tool (Piston ring
compressor) to compress rings. Guide connecting
rod into place on crankshaft.
Using a hammer handle, tap piston head to install
piston into bore. Hold ring compressor firmly against
cylinder block until all piston rings have entered
cylinder bore.

5) Install bearing cap (1):
Point arrow mark (2) on cap to crankshaft pulley
side.
After applying engine oil to rod bolts and 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.
NOTE
Before installing bearing cap, make sure that
checking for connecting rod bolt
deformation. Refer to “Piston Pins and
Connecting Rods Inspection”.
