Ring Nut
- Type: A specialized threaded fastener, typically a large, high-strength nut with specific features (e.g., castellated design, locking mechanism, or specific shape for a key/tool) used to secure a component, most commonly identified as the retaining nut for the front wheel bearing or hub assembly.
- Function: Its primary purpose is to precisely tighten and secure the front wheel bearing onto the spindle or hub, setting the correct preload and preventing lateral movement of the wheel. This is critical for:
- Wheel Security: Keeping the wheel securely attached to the vehicle.
- Bearing Longevity: Ensuring proper bearing preload for optimal lifespan and smooth operation.
- Safe Handling: Maintaining wheel alignment and preventing excessive play that could compromise steering and stability.
- Components: A single, robust, precisely machined metal nut, with internal threading. It may include features for a specific tightening tool (e.g., a spanner wrench or a large socket with specific lugs) and a locking mechanism (e.g., a cotter pin and castle nut design, or a self-locking thread).

Windshield Washer pump
The Windshield Washer Pump is a universally essential component for any vehicle, and your Maserati is no exception. It’s responsible for ensuring clear visibility by spraying washer fluid onto the windscreen, enabling the wiper blades to clean away dirt, dust, and debris. This pump is shared across several Maserati models, including the 4200, GranTurismo, and GranCabrio, which speaks to its robust and standardized design.
Product Name: Windshield Washer Pump
Application: Maserati 4200 GT (Coupé, Spyder, GranSport), GranTurismo, GranCabrio, and other compatible Maserati models.
Typical Part Number: 65358700 (This part number is widely cross-referenced for 4200, GranTurismo, GranCabrio, and even some Quattroporte models, making it a highly common Maserati washer pump).

- Mounting: Typically designed to be directly mounted into the washer fluid reservoir via a rubber grommet seal.
- Material: Durable, high-grade plastic housing (e.g., ABS) and corrosion-resistant internal components, built to withstand various washer fluid compositions and operating temperatures.
- Flow Rate/Pressure: Engineered to deliver sufficient pressure and volume of fluid for effective and even spray across the entire windshield.
- Durability: Resistant to vibrations, thermal cycling, and potential clogging from impurities in washer fluid.
WindShield Wiper Housing
- Type: Exterior body trim panel / housing for the windshield wiper mechanism.

- Components (if part of a larger assembly under this name): In some listings, this “housing” might refer to the main frame that holds the wiper motor and linkage. However, most commonly it refers to the visible exterior cover. The part number 66420800 specifically refers to a “Windshield Wiper Housing” that can be a larger assembly for the 4200.
Wiper Brush
-
- Type: Often conventional or beam-style (flat blade) wiper blade, designed for high-performance vehicles.
