3. If car cruises above engagement speed, screw the
orifice tube inward.
NOTE: Each 1/4 turn of the orifice tube will change
cruise speed approximately one mph. Snug-up lock nut
after each adjustment.
If a regulator is found to be defective and not simply out
of adjustment, it must be replaced. During replacement,
check the hoses which connect to the regulator and replace
any which are cracked or deteriorated.
SERVO UNIT
Before adjusting the servo cable, make sure the
carburetor is set at its lowest idle throttle position by
manually setting the fast idle cam at its lowest step with the
ignition switch "OFF". Adjust the cable so there is as little
lost motion at the servo as possible. Servo cable adjustment
procedures are shown on the mounting illustrations.
If the servo unit is found to be defective, replacement
is required. Note the condition of the hoses and replace any
which are cracked or deteriorated.
BRAKE RELEASE SWITCHES (FIG. 9-10)
Electric
The Cruise Master brake release switch electrical
contacts must be switched open when the brake pedal is
depressed .38" to .64", measured at the brake pedal.
An inoperative switch must be replaced. Switch
replacement procedure is identical to standard brake lamp
switch replacement.
An inoperative (sticking, plugged or leaking) vacuum
valve must be replaced. Vacuum valve replacement is similar
to brake switch replacement. Be certain that the hose to the
valve is connected firmly and is not cracked or deteriorated.
COLUMN MOUNTED ENGAGEMENT
SWITCH
The engagement switch is serviced only by replacement
of the turn signal lever assembly. Replacement procedures are
in the steering section, and wire routing is shown in Figs. 9-8
and 9-9.
Remove and Replace
Regulator and Servo mounting are shown in Figs. 9-15
through 9-20. Vacuum schematics are shown in Figs. 9-21
and 9-22. These do not show physical routings, but rather
proper vacuum connections.
Vacuum
The vacuum valve plunger must clear the pedal arm
when the arm is moved 5/16 inch, measured at the switch.
