FAW J6P Ashtray Assembly: Deconstructing 5 Critical Parts for Flawless Cabin Utility

Welcome to this in-depth analysis of the FAW J6P Ashtray Assembly for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This is not just an ashtray; it is an integrated utility module, including a 12V power port. This guide deconstructs the 5 critical components that form the complete system.

The FAW J6P Ashtray Assembly is a vital component for driver comfort and cabin functionality. In a modern heavy-duty truck, this area serves a dual purpose: as a traditional, flame-retardant ashtray and as the primary 12-volt power socket for charging devices and running auxiliary equipment.

This teardown will analyze the complete system, from the main housing (Part No. 8203010-EO6C) to the cigar lighter components (Socket and Head). We will also investigate its integration into the dashboard’s core structure. For a technician, understanding this system is key to solving electrical faults (like a non-working charger) or fixing rattles from a poorly-secured FAW J6P Ashtray Assembly.

The engineering of these components is focused on safety, specifically fire prevention. The materials used must be high-temperature, flame-retardant polymers and ceramics to handle the heat from the cigar lighter. We will explore the logic of each part, from the removable liner to the bimetallic switch in the lighter itself.

Core 1: The “Housing & Containment” Logic (The Ashtray)

This component is the primary housing that the user interacts with. It is engineered for safety, ease of use, and integration with the dashboard.

1. Component: ‘Ashtray Assy’ (8203010-EO6C) – Qty 1
This (Mark 1) is the complete FAW J6P Ashtray Assembly housing. The ‘Assy’ (总成) designation means it includes the outer shell, the damped opening mechanism, and the removable inner liner.

The Housing Logic: The main body is molded from a high-grade, flame-retardant polymer (like Polycarbonate or PC-ABS). This material is chosen for its high-temperature resistance, impact strength, and its ability to self-extinguish, which is a critical safety requirement for any component designed to hold embers.

The Damping Logic: A quality FAW J6P Ashtray Assembly does not just “spring open.” It features a damped mechanism, often a small, internal rotary damper with viscous grease. This allows the ashtray to open smoothly and silently when pressed, a sign of quality that also prevents the driver from being distracted by a sudden, jarring movement.

The Liner Logic: Inside the main housing is a removable metal liner. This is a critical feature for cleaning. This liner is typically stamped from aluminum or stainless steel, allowing it to be removed and washed without having to clean the entire assembly. It also provides a non-flammable first point of contact for embers.

The Service Logic: This ‘Assy’ is the main component a technician would replace. Common failures include a broken damping mechanism (causing the door to snap open or not stay closed), a cracked plastic housing, or a lost liner. The entire unit (8203010-EO6C) is replaced to solve these issues.

Core 2: The “Structural Interface” Logic (Mounting System)

This group of components defines how the FAW J6P Ashtray Assembly is securely mounted into the dashboard to prevent all rattles and vibration.

1. Component: ‘Instrument panel weld assy’ (5310030-A01) – Qty 1
This (Mark 3) is the host structure. This is not part of the ashtray, but rather the structural “backbone” of the entire dashboard, made of welded steel. This component is the primary anchor point, ensuring the ashtray is mounted to the truck’s chassis, not just flimsy plastic.

The Interface Logic: This steel ‘Weld Assy’ has specific, pre-threaded holes or brackets designed to align perfectly with the FAW J6P Ashtray Assembly housing. This ensures a deep, secure, and vibration-free installation.

2. Component: ‘Cross recessed pan head tapping screw’ (CQ2714219) – Qty 4
These (Mark 2) are the four fasteners that complete the installation.

The Tapping Screw Logic: These are not standard bolts. They are “self-tapping,” meaning they are designed to cut their own threads as they are driven into the plastic bosses of the dashboard trim. This is a high-speed, high-reliability manufacturing method that also provides excellent vibration resistance as the threads bite tightly into the material.

The Service Logic: A rattle from the FAW J6P Ashtray Assembly area is often caused by these four screws. A technician must ensure they are all present and tight. Over-tightening can strip the plastic, requiring a new dash component or a thread repair.

Core 3: The “Power Port” Logic (The Lighter Socket)

This is the “female” part of the 12V power system, which is a key utility of the modern FAW J6P Ashtray Assembly.

1. Component: ‘Cigar lighter socket assy’ (3725030-A01) – Qty 1
This (Mark 4) is the complete socket that is mounted within the ashtray housing. It is the power source for both the lighter head (Core 4) and any 12V accessory.

The Electrical Logic: This socket provides three connections. A center “hot” terminal (for the +12V feed), a main “ground” shell (the outer metal wall), and often a third terminal for an illuminated light ring, which helps the driver locate the port in the dark.

The Thermal Logic: This is the most critical logic. The socket must be made of a high-temperature, heat-resistant material, often a ceramic base or a phenolic-resin composite. A standard plastic socket would melt instantly when the red-hot lighter element is held against it. This ceramic design is a key fire-prevention feature.

The Standardization Logic: This socket is built to a global standard (often ISO 4165), which defines its diameter and depth. This standardization is why the FAW J6P Ashtray Assembly can also function as a “power port” for phone chargers, GPS units, or other 12V devices.

The Service Logic: This is a common point of failure. Technicians will often find the socket inoperative. This is rarely a failure of the socket itself, but rather a blown fuse (from an overloaded device) or corrosion on the contacts from moisture, which prevents a good connection.

Core 4: The “Heater Element” Logic (The Lighter Head)

This is the “male” plug and the actual heating component of the FAW J6P Ashtray Assembly system.

1. Component: ‘Cigar lighter head assy’ (3725020-A01) – Qty 1
This (Mark 5) is the removable, spring-loaded lighter head. It consists of the knob the driver touches and the internal heating element.

The Heating Logic: Inside the metal end is a high-resistance coil, typically made of a Nichrome (nickel-chromium) alloy. When the user pushes the lighter in, this coil makes contact with the +12V center pin and the ground shell, completing a circuit. The high resistance of the coil causes it to heat up to red-hot temperatures in seconds.

The Bimetallic Switch Logic: This is the “pop-out” mechanism. The lighter head has two small, springy arms that latch it into the socket when pushed. These arms are made of a bimetallic strip (two different metals bonded together).

As the Nichrome coil heats up, it also heats these bimetallic strips. Since the two metals expand at different rates, the strips bend. After 5-10 seconds, they bend enough to “unlatch” themselves from the socket, and a spring “pops” the lighter head out, breaking the circuit.

The Safety Logic: This simple, non-electric mechanism is a brilliant piece of engineering. It’s a temperature-activated switch that automatically prevents the element from overheating and causing a fire. It is a core safety feature of the FAW J6P Ashtray Assembly.

The Service Logic: These are the most common components to fail. The Nichrome coil can burn out, or the bimetallic strips can fatigue and stop latching. A technician will not repair this; the entire 3725020-A01 head is a single, low-cost replacement part.
