Inspection
1. Visually check the motor housing for evidence of cracks
or other damage. Check for excessive shaft end play
indicating worn or damaged bearings. Replace motor if
worn or damaged.
2. Inspect the wiper blade for serviceability. Replace wiper
blade when worn.
3. Inspect the wiper arm and parts of the linking component
kits (pantograph adapter, pivot shaft, wiper motor link
and crank, wiper motor bracket) for damage. Replace as
needed.
Installation
1. Verify the pivot shaft and the wiper motor link and crank
are in place on the motor bracket. (Washers and clip
springs fasten the link to the pivot pins on the crank and
the pivot shaft. The pivot shaft’s pivot pin mounts in the
hole nearest the end of the pivot shaft’s lever.)
2. Connect the wiper motor to the motor bracket with
screws and washers. Connect the wiper motor’s shaft to
the wiper motor crank with the nut and washer. Secure
the adapter and the gasket of the pantograph adapter to
the cab exterior with capscrews and lockwashers.
