Wiper Arm: Description and Operation
Wiper Arm - Description
DESCRIPTION
The wiper arms are the rigid members located between the wiper pivots that protrude from the cowl plenum cover/grille panel near the base of the
windshield and the wiper blades on the windshield glass. 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 (4) with a large tapered mounting hole (5) at one end. A molded black plastic cap fits over the wiper arm
retaining nut to conceal the nut and the mounting hole following wiper arm installation.
The wide end of a tapered, stamped steel channel (3) hinges on and is secured with a hinge pin (6) to the blade end of the wiper arm pivot end. One end
of a long, rigid, stamped steel strap (2), 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 (1). Concealed within the stamped steel channel is a long
tension spring (7) which is engaged with a wire hook on the underside of the die cast pivot end and is hooked through a small hole in the steel strap. The
entire wiper arm has a satin black finish applied to all of its visible surfaces.
The right and left wiper arms are unique and are not interchangeable. A wiper arm cannot be adjusted or repaired. If damaged or ineffective, the entire
wiper arm unit must be replaced.
