arm travel.
PULLEY HOUSING AND CABLE
ASSEMBLY
The windshield wiper pulley housing and cable assemblies, right
and left, are inserted in the openings in the front cowl panel at the
base of the windshield and are retained on the inside by a bolt and
clamp. A burred bushing is provided for attachment and adjustment
of the wiper arm. The small brass tube in each housing is for use with
a windshield washer attachment.
