SERVICE POINTS OF INSTALLATION
9. INSTALLATION OF DISTRIBUTOR
(1) Align the notch on the crankshaft pulley with the timing
mark “T” on the timing indicator to set the engine so
that the No. 1 cylinder is at the compression top dead
center.
(2) Align mating mark on distributor housing with mating mark
on distributor driven gear.
(3) Install distributor to cylinder head while aligning mating
mark on distributor attaching flange with center of distrib-
utor installing stud and tighten nut.
l-4. INSTALLATION OF SPARK PLUG CABLE
Improper arrangement of spark plug cables will induce voltage
between the cables, causing miss firing and developing a
surge at acceleration in high-speed operation. Therefore, be
careful to arrange the spark plug cables properly by the fol-
lowing procedure.
1. Install the spark plug cable clamps as shown in the illus-
tration.
2. The numerals on the support and clamp indicate the spark
plug cable No.
3. Pay attention to the following items when the spark plug
cables are installed.
(1) Install the cables securely to avoid possible contact
with metal parts.
(2) Install the cables neatly, ensuring they are not too
tight, loose, twisted or kinked.
