4448760100 Loader Parts Wiper Motor for ZW370 ZW550

The wiper motor with part number 4448760100 is a high-quality replacement component manufactured or certified by Hitachi, specifically designed for Hitachi ZW series wheel loaders. According to industry accessory matching conventions, this motor is mainly suitable for medium and large wheel loader models such as Hitachi ZW310-5, ZW310-6, ZW330-6, etc. It is used to drive the front windshield wiper to ensure clear visibility for drivers in rainy and snowy weather. Due to slight differences in electrical interfaces, installation brackets, and output torque among models of different generations and configurations, it is necessary to provide the specific model, serial number, and physical photos of the old motor of the equipment before procurement for final accurate matching.

The wiper motor is a permanent magnet DC motor, which serves as the core power source of the wiper system. It converts high-speed rotation into high torque and low-speed output through a built-in worm gear reduction mechanism, driving the wiper arm to oscillate back and forth. Motors usually have low-speed, high-speed, and intermittent working modes, controlled by a combination switch in the cab, and integrated with an automatic reset device to ensure that the wiper blades can accurately return to the initial (parking) position after the switch is turned off. To adapt to the harsh working environment of the loader (dusty, humid, continuous vibration), the motor housing is made of high-strength engineering plastic or metal material, and has a high level of protection, which can effectively prevent dust and water.

The maintenance core of this motor lies in regular inspection, correct use, and preventive maintenance. Daily use: It is necessary to avoid starting the wiper when the windshield is dry. Instead, spray glass water for lubrication to reduce motor load and rubber strip wear. Regularly remove dust and oil stains from the surface of the motor, but be careful to prevent the high-pressure water gun from directly flushing the wiring ports. Troubleshooting: If the wiper does not work, has abnormal speed, or cannot be reset, the corresponding fuses, relays, and control switch circuits should be checked first. These are often the more common fault points.
