Cruise Control Servo Cable: Adjustments
Power Unit Adjustment
With air conditioner off and idle speed solenoid disconnected (if equipped), set curb hot idle speed to 500 RPM, then shut engine off. Unsnap swivel
from ball stud, then hold chain taught. Center of swivel should extend 1/8 inch beyond center of ball stud. If not, remove swivel and chain assembly
retainer, then position chain into swivel cavities which will give adjustment stated above. Reinstall retainer.
Engagement-Cruising Speed Zeroing
The only transducer adjustment possible is engagement-cruising speed zeroing. No adjustment should be performed unless the servo unit and brake
release switches are properly adjusted and all vacuum lines are checked for kinks, leaks or punctures.
If cruising speed is lower than engagement speed, loosen orifice tube locknut and turn tube counterclockwise. If cruising speed is greater than
engagement speed, turn orifice tube clockwise. Each 1/4 turn of orifice tube will alter engagement-cruising speed approximately one m.p.h.. After
adjustment is completed, tighten locknut and test system at 50 m.p.h..

automatically adjust switch and valve.
Clutch Release Switch & Valve
With clutch pedal at rest, push switch and valve assembly forward against bracket or arm. Pull pedal rearward with a force of 15---20 lbs. to
