(d) Check the valve overall length.
Standard overall length:
Intake
98.29±98.79 mm (3.8697±3.8894 in.)
Exhaust
98.84±99.34 mm (3.8913±3.9110 in.)
Minimum overall length:
Intake
98.19 mm (3.8657 in.)
Exhaust
98.74 mm (3.8874 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder
or replace the valve.
NOTICE: Do not grind off more than the minimum overall
length.
8. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a thin coat of prussian blue (or white lead) to the valve
face. Lightly press the valve against the seat. Do not rotate
the valve.
(c) Check the valve face and seat for the following:
wIf blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
wIf blue appears 360° around the valve seat, the guide
and face are concentric. If not, resurface the seat.
wCheck that the seat contact is in the middle of the valve
face with the following width:
Intake
1.0±1.4 mm (0.039±0.055 in.)
Exhaust
1.2±1.6 mm (0.047±0.063 in.)
If not, correct the valve seats as follows:
wIf the seating is too high on the valve face, use 15° and
45° cutters to correct the seat.
± ENGINEENGINE MECHANICALEG±55

wIf the seating is too low on the valve face, use 60° and
45° cutters to correct the seat.
(d) Hand±lap the valve and valve seat with an abrasive
compound.
(e) After hand±lapping, clean the valve and valve seat.
9. INSPECT VALVE SPRINGS
(a) Using a steel square, measure the deviation of the valve
spring.
Maximum deviation:
2.0 mm (0.079 in.)
If deviation is greater than maximum, replace the valve
spring.
(b) Using vernier calipers, measure the free length of the valve
spring.
Free length:
Blue painted mark
41.74 mm (1.6433 in.)
Yellow painted mark
41.70 mm (1.6417 in.)
If the free length is not as specified, replace the valve spring.
(c) Using a spring tester, measure the tension of the valve spring
at the specified installed length.
Installed tension:
186±206 N (19.0±21.0 kgf, 42±46 lbf) at 34.5 mm
(1.358 in.)
If the installed tension is not as specified, replace the valve
spring. EG±56

(b) Overlap the 2 stripped wire ends inside of the
pressure±contact sleeve as illustrated in the left.
HINT: The blue pressure±contact sleeve
(Part No. 82999±12020) is available individually.
HINT: You might find it easier if you use a miniature screwdriv-
er as a guide as you insert wires into the sleeve.
(c) The crimping tool (AMP Part No. 169060) has color marks on
it. Place the sleeve in the correct section of the tool according
to the color of the sleeve itself.
(d) With the center of the sleeve correctly placed between the
crimping jaws, squeeze the crimping tool until either end
comes into contact at the section marked by ºCLOSE HEREº.

Wire Harness Repair Manual (RM1022E)
What is Wire Harness?
The wire harness (W/H) is systems of electric wires for
automobiles to connect all the electronics parts in
automobile electrically and work them. As more electronics
parts are introduced in automobiles recently, the electric
wires used for the wire harness are increasing in number
and the structure is becoming more complicated. As a
result of that, there are hundreds of connectors, which is
the parts which connects wires mechanically and
electrically, in one vehicle. Therefore, numbers of the
connector terminal (Terminal) or the connector housing
(Housing) are designed to meet many kinds of uses of
circuits. Various components have been improved to
ensure the product reliability or realize a wider space in the
vehicles.
Wire Harness Components
Wire harness mainly consists of wires, terminals, or
housings.
There are various components are designed for many
parts of vehicles, such as one with high heat±resistance,
water±resistance, or bending ability, ones have different
current capacities, or ones are hardly influenced by
electromagnetic noise.
Electric Wire
The electric wires used for the wire harness consists of the
conductor made from numbers of twisted mild copper wire
with a diameter of less than 0.5 mm and the insulator
surrounding the conductor.
The insulator is generally made from vinyl chloride and
covers the conductor with even thickness. The insulators
are color±coded in order to distinguish each wire. The base
colors or the stripe patterns is used to make difference
between insulators. Each color of wires is indicated by the
abbreviation in the repair manual and the electrical wiring
diagram.

The first letter indicates the basic wire color and the second
letter indicates the color of the stripe.
Terminal and housing
Terminal connects wires and housing insulates connecting
parts.
There are the male terminal and the female terminal. The
types of terminals are decided by tab width of male
terminal. And the terminal with the rubber plug or the
rubber ring is used in the part, such as the engine
compartment, which become wet. For the circuit with slight
current at EFI system or ABS system, the gold±plated
terminal is introduced for ensuring reliabilities.
As the number of the circuit is increasing recently, there are
new types of parts introduced. For example, there is the
hybrid type housing, which is a combination of terminals
with different tab width, such as the power source terminal
or the signal terminal. Also, new type of connector such as
the double lock housing, which is designed with the
retainer in addition to the lance to prevent terminal from
slipping off, is available. The new type of connectors are
produced to realize higher product reliabilities and utilized
widely recently. The major characteristics of these new
connectors are shown in the table 1.
There are two types of lances: housing lance, which is
inside the housing and terminal lance, which is inside the
terminal.A
