The WWF wiper system provides a totally self-contained oscillating shaft requiring no external linkage. The universal popularity of the WWF motor is enhanced by the fact that the motor gives a marine quality sealed casing. All parts exposed to weather are corrosion resistant. Consequently, the WWF motor is ideal for any type of service or vehicle. WWF motors default at a 110o wipe angle that can be adjusted to 1 of 7 different wipe angles.
