WIPER ARM
DESCRIPTION
The wiper arms are the rigid members located
between the wiper pivots that protrude from the cowl
top panel near the base of the windshield and the
wiper blades on the windshield glass (Fig. 15). These
wiper arms feature an over-center hinge that allows
easy access to the windshield glass for cleaning. The
wiper arm has a die cast metal pivot end with a
large tapered mounting hole at one end. A removable
molded black plastic pivot cover fits loosely over and
pivots on the wiper arm hinge pin, then snaps over
the pivot end to conceal the wiper arm retaining nut.
The wide end of a tapered, stamped steel channel
hinges on and is secured with a hinge pin to the
pivot end of the wiper arm. One end of a long, rigid,
stamped steel strap, with a small hole near its pivot
end, is riveted and crimped within the narrow end of
the stamped steel channel. The tip of the wiper blade
end of this strap is bent back under itself to form a
small hook. Concealed within the stamped steel
channel, one end of a long spring is engaged with a
wire hook on the underside of the die cast pivot end,
while the other end of the spring is hooked through
the small hole in the steel strap. The entire wiper
arm has a satin black finish applied to all of its vis-
ible surfaces.
Near the hook of the wiper arm steel strap is a
locating hole for the washer nozzle that is mounted
on the wiper arm. A U-shaped molded plastic guard
snaps onto the underside of the strap to conceal and
protect the washer nozzle hose. There are also two
small molded plastic washer nozzle hose routing
brackets clipped onto the underside of the wiper arm
pivot end.
The wiper arms for this model are unequal in
length, with the longer arm being installed on the
left (driver) side of the windshield. A wiper arm can-
not be adjusted or repaired. If damaged or faulty, the
entire wiper arm unit must be replaced. The washer
nozzle, nozzle hose, routing brackets, and pivot end
cover are available for individual service replace-
ment.
