CHAPTER III WINDSHIELD WASHER
Fig. 1 Windshield Washer Installation (80" Wide Cab Shown)
The windshield washer (Fig. 1) consists of a reservoir
mounted motor driven displacement type pump that delivers
washer solution to the windshield through hoses and nozzles
in the wiper arms. Since the pump motor is integral with
reservoir, only the complete assembly is available for service.
Two types of controls are used with the windshield
washer namely-an integral with wiper control switch type for
electric wipers and an independent control type for air wipers.
(Independent switch is mounted on instrument panel directly
below wiper control valve.) You can operate windshield
washer with either type control simply by pushing in on control
switch for as long as you want nozzles to spray. Spray will
stop as soon as control is released. MAINTENANCE
A minimum of service is required to keep windshield
washer operating. Keep reservoir filled with IH No. 996726-
R2 windshield washer solvent and keep wiper nozzles clean.
If dirt enters reservoir, remove reservoir and flush out with
clean water. Refill reservoir with specified solvent after
