The Connect rod and bracket assembly is the mechanical linkage that transmits motion from the wiper motor to the wiper arms. Manufactured from high‑strength steel with corrosion‑resistant coating, it features precision‑machined pivot points that ensure smooth, rattle‑free operation. This assembly is designed to withstand the repetitive motion and varying loads of wiper operation, providing reliable performance over the vehicle’s lifetime. Its robust construction prevents flexing and misalignment, ensuring that the wiper blades maintain consistent contact with the windshield for optimal clearing performance.
The Scrape assembly is the wiper blade unit that makes direct contact with the windshield. It features a high‑quality rubber squeegee that effectively removes water, snow, and debris with each pass. The blade is designed with a spoiler to maintain consistent pressure against the glass at highway speeds, ensuring streak‑free wiping. Its durable construction resists cracking and hardening, providing long‑lasting performance even in extreme temperatures. This assembly is a direct replacement for the original wiper blades, restoring full clearing capability to the Driving cab washer device.
The Scrape assembly for the wiper arm is the metal linkage that connects the wiper motor to the blade. Manufactured from high‑strength steel with a corrosion‑resistant finish, it provides the necessary spring tension to keep the blade firmly against the windshield. The arm features an adjustable pivot that allows for precise positioning of the blade, ensuring optimal clearing coverage. Its robust construction and durable coating make it a reliable component of the Driving cab washer device.
The Windscreen wiper motor and bracket assembly is the power unit of the Driving cab washer device. It features a high‑torque electric motor with integrated gear reduction, providing smooth and consistent wiper operation at multiple speeds. The motor is sealed against moisture and dust, ensuring reliable performance in all weather conditions. The mounting bracket is precision‑formed to secure the motor to the cab structure, reducing vibration and noise. This assembly includes the necessary electrical connectors for a simple plug‑and‑play installation, restoring full wiper functionality to the vehicle.
The Hex bolt is a high‑strength fastener used to secure the wiper motor, bracket, and linkage components. Manufactured from grade 8.8 steel with a corrosion‑resistant coating, it provides a secure, vibration‑proof connection that maintains clamping force under extreme conditions. Its precise threading and hex head allow for easy installation with standard wrenches.
The Washer (large) is a wide‑diameter flat washer that distributes clamping load evenly under the hex bolt heads. Manufactured from steel with a zinc‑plated finish, it prevents damage to the mounting surfaces and ensures a secure, rattle‑free connection. Its larger surface area is ideal for applications where high clamping forces are required, such as the wiper motor and bracket mounting.
The Spring washer is a split‑helical locking washer that provides preload and prevents loosening of fasteners under vibration. Manufactured from high‑carbon spring steel, it retains its resilience over a wide temperature range, maintaining tension on the bolt and preventing it from backing off. This washer is used in critical joints of the Driving cab washer device to ensure that all connections remain tight and secure.
The Flat washer is a standard flat disc used to distribute load and protect the mounting surface from damage. Manufactured from steel with a protective coating, it provides a smooth bearing surface under the bolt head, reducing friction and preventing galling during tightening. This washer is an essential hardware component of the Driving cab washer device, ensuring proper torque and load distribution.
