WINDSHIELD
WASHER PUMP

The windshield washer pump used on the 2-speed Type

"E"
wiper motor assembly is a positive displacement

type pump employing a small bellows, bellows spring and

valve arrangement. The pumping mechanism is actuated

by a four lobe cam and driven directly by the wiper motor

(fig. 71). Thus, when the wiper is operated, this rotor is

always turning with the gear. Programming is accom-

plished electrically and mechanically by a relay assembly

and ratchet wheel arrangement.

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.
