Welcome to this critical deconstruction of the FAW J6P Left Rearview Mirror for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This is not just a piece of glass; it is a complex, multi-functional safety system. This guide analyzes the 3 critical component types for this driver’s side assembly.
The FAW J6P Left Rearview Mirror is the driver’s primary tool for monitoring traffic, obstacles, and the rear of the trailer. For a 6×4 dump truck operating on chaotic job sites and in tight urban environments, a clear, stable, and comprehensive field of vision is non-negotiable.
This teardown will analyze the main mirror assembly (8202015-A01J), its cosmetic cover, and its high-strength mounting hardware. We will explore the integrated electrical systems, such as the remote adjustment motors and the heating element, which make the FAW J6P Left Rearview Mirror a true all-weather, functional tool.
For a technician, understanding this system is key to diagnosing common electrical faults, replacing damaged glass, or servicing the mounting. A vibrating, loose, or non-functional FAW J6P Left Rearview Mirror is a critical safety defect that can ground a vehicle, and replacing it correctly is essential.
This is the core component of the FAW J6P Left Rearview Mirror system. It is a complete, factory-sealed assembly containing all functional and structural parts.
1. Component: ‘Left Rearview Mirror Assy’ (8202015-A01J) – Qty 1
This (Mark 1) is the entire assembly. The ‘Assy’ (总成) designation is critical, as it confirms this part includes the outer housing, the internal mounting arm, the primary and convex glass, the adjustment motors, and the heating element.
The Dual-Mirror Logic: This is not a single mirror. A heavy truck FAW J6P Left Rearview Mirror is a “dual-view” system. It contains two separate pieces of glass:
1. **Primary Mirror (Upper):** A large, flat piece of glass. Flat glass provides a 1:1 reflection, allowing the driver to accurately judge the distance and speed of vehicles behind them.
2. **Convex Mirror (Lower):** A smaller, curved piece of glass. This convex “fisheye” shape bends the light, providing a much wider field of vision. Its sole purpose is to eliminate the truck’s massive “blind spot” directly beside and below the cab, revealing cars, cyclists, or obstacles.
The Housing Logic: The outer shell of the FAW J6P Left Rearview Mirror is molded from a high-impact, durable polymer like ABS (Acrylonitrile Butadiene Styrene). This material is chosen for its strength, light weight, and resistance to stone chips. Its aerodynamic “low-drag” shape is designed to slice through the air, preventing wind-buffeting from shaking the mirror glass.
The Structural Arm Logic: This housing is mounted on an extremely rigid arm, often made of die-cast aluminum or steel. This arm’s only job is to be rigid. Any flex in this arm would cause the mirror to vibrate, rendering it useless. This solid mounting is a hallmark of a quality heavy-duty FAW J6P Left Rearview Mirror.
The Breakaway Logic: This arm is often designed with a high-tension spring-loaded pivot. This allows the entire mirror assembly to “break away” or fold inward upon a significant impact (like hitting a tree branch). This saves the mirror from being torn off, allowing the driver to simply “pop” it back into place.
Housed within the main assembly is the sophisticated electrical system that elevates the FAW J6P Left Rearview Mirror from a simple reflector to an active safety tool.
The Remote Adjustment Logic: Inside the housing, behind the primary glass, is a 4-way electric motor actuator. This allows the driver to remotely adjust the mirror’s angle (up/down/left/right) from a switch inside the cab. This is a critical safety and convenience feature, allowing for precise adjustments without leaning or stopping.
The Heating Logic: Laminated to the back of both mirror glass panels is a heating element, similar to a rear window defroster. This element is tied to the truck’s defrost circuit. When activated, it quickly melts ice and evaporates fog or mist from the mirror’s surface, ensuring 100% visibility in poor weather. A non-heated mirror is a major liability in cold or wet climates.
The Wiring Harness Logic: The mounting arm of the FAW J6P Left Rearview Mirror is hollow, acting as a protected conduit. A factory-sealed wiring harness runs from the motor and heater, through this arm, and into the door, where it connects to the main body harness. This design protects the wires from snagging, UV damage, and water intrusion.
The Service Logic (Electrical): Electrical faults are common service items. A technician diagnosing a non-functional FAW J6P Left Rearview Mirror would first check the fuse, then the switch, and finally the integrity of this harness connector in the door. The motors and heating elements are considered part of the main 8202015-A01J assembly and are not typically replaced individually.
This component is the “finishing touch” that hides the mounting hardware and integrates the FAW J6P Left Rearview Mirror with the cab’s interior.
1. Component: ‘Left Lower Mounting Base Decorative Cover’ (8202021-A01) – Qty 1
This (Mark 2) is a precision-molded plastic trim piece. Its sole function is cosmetic and integrative. It is the last part to be installed.
The Concealment Logic: The primary job of this cover is to hide the “ugly” parts of the installation. Once the FAW J6P Left Rearview Mirror is securely bolted on (with Core 4 fasteners), this cover snaps into place over the mounting flange and the bolt heads.
The Aesthetic Logic: This part (8202021-A01) is molded with a specific color and “grain” texture to perfectly match the truck’s A-pillar and door panel trim. This creates a seamless, factory-finished look, rather than exposing a raw metal bracket.
The Service Logic: This is the first part a technician must remove to service the FAW J6P Left Rearview Mirror. It is almost always held on by hidden plastic clips. A plastic trim-removal tool must be used to carefully pry it off without breaking these clips or scratching the surrounding paint. These covers are fragile and a common replacement item during mirror service.
This group of fasteners is the final, and most critical, link. They are all that holds the entire FAW J6P Left Rearview Mirror assembly to the truck, fighting against constant wind-force and vibration.
1. Component: ‘Socket Head Cap Combination Screw’ (T2180630F6) – Qty 5
This (Mark 3) is a set of five identical, high-strength bolts.
The Socket Head Logic: The part name ‘Socket Head Cap Screw’ (内六角圆柱头) specifies an Allen-key (hex) drive. This is a deliberate engineering choice. This type of drive allows for very high torque to be applied in a confined space (i.e., inside the door frame) where a large socket wrench cannot fit. It also provides a secure, non-slip grip, preventing the “rounding off” that can happen with a Phillips screw.
The Combination Logic: The term ‘Combination Screw’ (组合螺钉) is critical. It means each bolt (T2180630F6) has a pre-installed, “captive” lock washer. This is the single most important feature for a component subject to extreme, constant vibration.
This captive washer exerts constant spring tension on the bolt, making it impossible for it to vibrate loose. This is what guarantees the FAW J6P Left Rearview Mirror stays rigid and rattle-free for years.
The Service Logic: A “vibrating” mirror is almost always caused by these five bolts losing torque. A technician must remove the decorative cover (Core 3) to access and re-torque these fasteners. When installing a new FAW J6P Left Rearview Mirror, these bolts must be tightened in a star pattern to ensure the mounting flange sits perfectly flat against the door frame.
