NON-DEPRESSED PARK WIPER

CHEVELLE, CHEVY II AND CAMARO

The Type "E" two-speed electric windshield wiper

assembly (fig. 64) incorporates a non-depressed type

(blades park approximately 2" above windshield molding)

motor and gear train. The rectangular, 12 volt, com-

pound wound motor is coupled to a train consisting of a

helical drive gear at the end of the motor armature shaft,

an intermediate gear and pinion assembly, and an output
gear and shaft assembly. The crank arm is attached to

the output gear shaft.

Two switches, connected in parallel, control the start-

ing, stopping and parking of the Type "E" wiper motor.

The manually operated start, stop switch is located on

the instrument panel, while the cam operated park switch

is located in the wiper gear box.

DEPRESSED PARK 2-SPEED WIPER

CHEVROLET

GENERAL DESCRIPTION

The Type "C" two speed electric wiper assembly (fig.

74) incorporates a depressed park type (blades park

against windshield lower molding when the motor is

turned off) motor and gear train. The wiper has a com-

pound wound 12 volt motor and a gear box section con-

taining the gear mechanism and relay control. The motor

armature is fitted with a worm gear which drives the

main gear assembly and crank arm.

The relay control, consisting of a relay coil, relay

armature and switch assembly, is located in the gear box
section bid controls the starting and stopping of the wiper

through a latching mechanism (fig. 75).

An electric washer pump is mounted on the gear box

section of the wiper and is driven by the wiper unit gear

assembly (fig* 75).

The overhaul procedures for the wiper are broken down

into three major areas: The motor section, gear box

section and washer pump section. Each section maybe

serviced independently of the other.

1.
If new field and case assembly is being installed,

splice the black and black with pink stripe leads of

the new field with the corresponding leads of the

wiper.

2.
Install the rubber thrust disc, steel thrust disc and

felt lubricating washer in the case assembly bearing

in the order indicated.

Lubricate end of armature shaft that fits in case

bearing. Next, install thrust ball in end of shaft.

4.
Assemble armature in the case and field assembly.

5.
Position the partially assembled brush plate over the

armature shaft far enough to allow re-assembly of

the remaining brush in its brush holder;- then position

the brush plate assembly on the mounting tabs in the

position shown in Figure 78.

NOTE: Circuit breaker ground lead will not

reach circuit breaker terminal if brush plate is

positioned wrong.

6. Center the brush plate mounting holes over the

mounting tabs and bend the tabs toward the brush

holders as required to secure the brush plate in

position.

CAUTION: Be sure tabs are centered in brush

plate mounting holes.

7.
Remove brush retainer clips and resolder circuit

breaker ground lead to circuit breaker. Refer to

Figure

8. If new case and field assembly'is used, scribe a line

on it in the same location as the one scribed on the

old case. This will insure proper alignment of the

new case with the scribed line made on the housing

(Step
1
under Brush Plate Removal).

9. Position armature worm shaft inside the housing and,

using the scribed reference marks, line up as near
