(b) Disconnect the high−tension cord at the grommet.
Do not pull on the cord.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.Do not wipe any of the oil from the grommet after the
high −tension cord is disconnected.
8. INSPECT HIGH−TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance. Maximum resistance: 25 k Ω per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high −tension cord.
9. RECONNECT HIGH− TENSION CORDS TO DISTRIBU-
TOR CAP AND IGNITION COIL
(a) Assemble the holder and grommet.
HINT:
Connect the high− tension cords to the distributor cap as shown
in the illustration.
(b) Align the spline of the distributor (ignition coil) with the spline of the holder, and push in the cord.

NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the coils themselves. ”Cold” is from −10° C
(14 °F) to 50° C (122°F) and ”Hot” is from 50 °C (122° F) to
100 °C (212 °F).
28. DISCONNECT DISTRIBUTOR CONNECTOR
29. REMOVE DISTRIBUTOR CAP WITHOUT DISCON- NECTING HIGH−TENSION CORDS
30. REMOVE ROTOR
31. INSPECT AIR GAPS
Using a thickness gauge, measure the gap between the signal
rotor and the pickup coil projection. Air gap: 0.2 − 0.4 mm (0.008 − 0.016 in.)
If the gap is not as specified, replace the distributor housing.
32. INSPECT SIGNAL GENERATOR (PICKUP COIL) RE- SISTANCE
Using an ohmmeter, check that the resistance of the pickup coil. Pickup coil resistance:
Cold G1 and G
G2 and G
NE and G185 − 275 Ω

If the resistance is not as specified, replace the distributor hous-
ing.
33. REINSTALL ROTOR
34. REINSTALL DISTRIBUTOR CAP
35. RECONNECT DISTRIBUTOR CONNECTOR
NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the sensor itself.
”Cold” is from −10° C (14°F) to 50° C (122°F) and ”Hot” is
from 50° C (122°F) to 100° C (212°F).

INSTALLATION
1. CHECK NO.1 CYLINDER TO TDC/COMPRESSION
If necessary, remove the cylinder head cover, and check these
conditions:
Turn the crankshaft pulley and align its groove with
the timing mark ”0” of the timing chain cover.
Verify that the timing marks with 1 and 2 dots are in
straight line on the cylinder head surface as shown
in the illustration.
If not, turn the crankshaft 1 revolution (360°) and align the mark
as above.
2. INSTALL DISTRIBUTOR
(a) Install a new O−ring to the distributor.
HINT:
Always use a new O −ring when installing the distributor.
(b) Align the groove of the distributor housing with the protru-
sion on the driven gear.
(c) Apply a light coat of engine oil on the O −ring.
(d) Insert the distributor, aligning the center of the flange with
that of the bolt hole on the cylinder head.
(e) Lightly tighten the hold −down bolt.
3. INSTALL DISTRIBUTOR CAP
4. CONNECT DISTRIBUTOR CONNECTOR
5. CHECK IGNITION TIMING (See page EM−10)
