* The driver's seat only may be Special Or-
dered with Four-Way powered seat adjusters.
All seat adjusters and stationary supports are
bolted to the seat bottom frame; however, a com-
bination of bolts and/or nuts are used to retain
the adjusters or stationary supports to the floor
pan assembly. The four-way (tilt) seat adjusters
are actuated by a 12-volt, reversible shunt wound
motor with a built-in circuit breaker.
The seat adjuster operating mechanism incor-
porates a transmission assembly which includes
two solenoids and two drive cables leading to the
seat adjusters. One solenoid controls the vertical
movement of the seat while the other solenoid
controls the horizontal movement of the seat.
When the control switch is actuated, the motor
and one of the solenoids are energized simulta-
neously. Then the solenoid plunger engages with
the driving gear dog. The driving gear rotates
the drive cables and operates both adjusters.
When the adjusters reach their limit of travel, the
drive cables stop their rotating action and torque
is absorbed by the rubber coupler connecting the
motor and transmission. When the switch con-
tacts are opened, a return spring returns the
solenoid plunger to its original position disen-
gaging it from the driving gear dog.
