CLOCK ADJUSTMENT
I
Adjustment of the clock is auto-
matic. If the clock runs slow or fast,
i
merely reset the clock to the proper
time. This action adjusts the clock
automatically. Turning the knob clock-
wise, the clock will go faster. By turn-
ing the knob counterclockwise the
clock will go slower.
The clock fuse is in the fuse panel
which is mounted on the dashboard
above and to the right of the brake
pedal.
SPEEDOMETER REPAIR
PROCEDURES
LOOSE CABLE ATTACHING
N UTS
1. Cable nuts should be tightened
with pliers to approximately 18 to 25
in-lbs.
2. Cable nuts should start and run
up freely by hand for at least three to
four turns.
3. A loose cable nut can cause a
bent cable core. Tightening will not
always correct the problem.
DEFECTIVE CABLE CORE
AND HEAD
Before removing a speedometer
head, disconnect the cable a t the
head and insert a short section of
cable core in the head. Rotate the
section of core to check for any drag-
ging or noise. The speedometer shaft
should turn freely and evenly.
If a new speedometei head is being
installed, examine the square drive hole
for sufficient lubricant. If lubricant is
needed, apply a 3/16 inch diameter
ball of C5AZ-19581-A lubricant in the
drive hole. Also set the odometer to
the reading shown on the head being
replaced.
DEFECTIVE CABLE CORE
AND HOUSING
1.
To check for a kinked cable core
remove and wipe dry. Lay the core
out straight on a flat surface and roll
it back and forth. Any kinks or
damage will be seen. Then take an
end in each hand, allowing core to
hang in approximately a 9 to 12 inch
loop. Rotate both ends'to be sure core
turns evenly.
2. Routing of the cable housing is
particularly important where the cable
leaves the speedometer head. The opti-
mum routing would provide that the
cable and housing take virtually no
change of direction for a t least a
length of 8 inches from the speedo-
meter head.
3. When installing a new cable and
housing it is necessary that extra care
be taken to see 'that the new assembly
is guided and routed properly to elim-
inate any kinks.
4. Proper lubrication of the cable
core is accomplished by a light appli-
cation of BSAZ- 1958 I-A lubricant aft-
er the cable has been wiped clean. A
light film is all that is required.
DEFECTIVE DRIVE AND
DRIVEN GEARS
1.
A scored, nicked or gouged
driven gear is usually indicative of a
defective drive gear on those vehicles
that have the drive gear integral with
the transmission output shaft. The
output shaft should be carefully in-
spected for imperfections and replaced
if necessary.
2. A driven gear with two or three
adjoining teeth badly scored is indica-
tive of improper assembly procedure.
The gear should be inserted in the
transmission while simultaneously
turning the drive shaft. This will in-
sure initial gear engagement and pre-
vent gear damage. Force should never
be used.
3. Whenever a drive gear is re-
placed, a new driven gear should also
be installed, regardless of its apparent
condition.
