Joints de porte FAW ET déflecteurs de pluie: Le 6 Les secrets essentiels d'un silencieux, Sec, et cabine sans parasites

Welcome to this in-depth guide on the Joints de porte FAW ET déflecteurs de pluie (Assemblée 687). C'est le complet, 6-component-type, “environmental logic” kit for the ‘FAW Front Door’ (Assemblée 683) sur le FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur. This assembly is a critical system with a “triple-threat” logique: 1) to provide a 100% waterproof seal, 2) to eliminate wind noise (Nvh), et 3) to protect the driver from insects and road spray.

Le “logique” de la Joints de porte FAW ET déflecteurs de pluie assembly is to create a complete, multi-layered “comfort cell” for the driver. This is not one single part, but a system of primary seals (joints), secondary seals (runnels), and tertiary accessories (deflectors, nets). This system works with the ‘Door Trim’ (Assemblée 685) to guarantee a quiet, dry, and comfortable cab environment, which is essential for reducing driver fatigue.

This expert analysis is a vital resource for cab technicians, collision repair specialists, and parts managers. Nous déconstruirons l'ensemble Joints de porte FAW ET déflecteurs de pluie kit into its 6 Unité minimale utilisable distincte (MSU) genres. Nous analyserons le “dual-sweep” logic of the window seals, le “low-friction” logic of the runnels, et le “driver comfort” logic of the rain deflectors and insect nets.

Cœur 1: Le “Aero & Météo” Logique (MSU 1 & 6) (Le “Plus long” Module)

This group of MSUs from the Joints de porte FAW ET déflecteurs de pluie kit is the “first line of defense” against the elements and wind noise. It consists of the outer “squeegee” and the aerodynamic “visor.”

1. MSU 1: ‘Outer Window Sealing Strip’ (6103035-A01 / 6103040-A01)

C'est le “outer window sweep” ou “dew wipe.” C'est “logique” is to be a squeegee. It mounts on the *outside* of the ‘Front Door’ (683) shell and presses tightly against the glass.

Water-Shedding Logic: This is its primary function. As the ‘Door Glass’ (683) is rolled down, this strip’s EPDM rubber “lip” scrapes 99% of the water, glace, and dust off the glass. Ce “logique” est critique. It prevents this “dirty” water from being pulled *inside* the door shell, which would otherwise drench the ‘Window Lifter’ (683) and cause it to rust and fail. A failed outer sweep is a primary cause of window regulator failure.

Construction: This MSU has a “dual-durometer” logique. It has a rigid “clip” portion (made of hard, glass-filled polymer) that snaps into the door shell, and a soft, flexible, co-extruded EPDM rubber “lip” that provides the seal.

2. MSU 6: ‘Front Door Rain Deflector’ (6101551BD04 / 6101552BD04)

C'est le “vent visor” ou “wind deflector.” This is a key “driver comfort logic” component in the Joints de porte FAW ET déflecteurs de pluie kit.

Aero Logic (Ventilation): C'est “logique” is to allow the driver to *crack the window open* for fresh air (critical for fighting fatigue) *while it is raining*. The panel’s aerodynamic shape “deflects” the rain up and over the open gap.

Logique NVH (Buffeting): This MSU also solves “wind buffeting.” Driving at high speed with a window cracked open can create a painful, low-frequency “thumping” ou “buffeting” sound as air is pressurized inside the cab. This deflector’s “logique” is to act as a “fairing,” smoothing the airflow past the opening and eliminating this noise.

Cœur 2: Le “Silent Seal” Logique (MSU 2 & 3)

This group of MSUs from the Joints de porte FAW ET déflecteurs de pluie kit forms the “inner” joint, which is critical for NVH (Noise, Vibration, Harshness) et l'étanchéité.

MSU 3: ‘Door Glass Runnel’ (6103051-A01 / 6103052-A01)

C'est le “glass run channel.” This is the EPDM rubber U-channel that the *front* and *rear* vertical edges of the ‘Door Glass’ (683) slide into.

C'est “logique” is twofold: 1) It creates the primary vertical *seal* against wind and water. 2) It is lined with a “flocked” (fuzzy felt) material. Ce “low-friction logic” is essential for the ‘Window Lifter’ (683) moteur, as it allows the glass to slide smoothly with minimal effort. It also provides the main “anti-hochet” logique, holding the glass snugly to prevent it from “clattering” in its frame.

MSU 2: ‘Inner Window Port Sealing Strip’ (6102065BD04 / 6102070BD04)

C'est le “inner window sweep.” C'est le “twin” to MSU 1, but it mounts on the *inside* of the door, as part of the ‘Door Trim’ (685). C'est “logique” is the final “cosmetic” et “acoustique” joint. It hides the “écart” between the trim panel and the glass, and its flocked lip provides a final, silent “anti-hochet” tampon.

Cœur 3: Le “Pest & Debris” Logique (MSU 4 & 5)

This final group of MSUs in the Joints de porte FAW ET déflecteurs de pluie kit is a pure “driver comfort” et “regional” logique.

MSU 5: ‘Front Door Insect Net’ (6103105BD04 / 6103110BD04)

C'est le “anti-insect” logique. It is a custom-fit, tear-resistant mesh screen. C'est “logique” is critical for sleeper cabs or for drivers who are parked for loading/unloading. It allows the window to be fully rolled down for maximum ventilation, while providing a 100% barrier against mosquitoes, flies, and other pests.

MSU 4: ‘Front Door Insect Net Hook Strip’ (6103113BD04)

C'est le “mounting logic” for the net. C'est le “hook” side of a “hook-and-loop” (Velcro-style) fastener system. This adhesive-backed strip (MSU 4) is applied to the door frame. The net (MSU 5) has the “loop” side sewn onto its border. Ce “logique” allows the driver to install or remove the net in seconds, with no tools.

Cœur 4: Le “Installation” Logique (MSU 7 & 8)

Le (implied) hardware for the Joints de porte FAW ET déflecteurs de pluie is listed in a related assembly (684). This hardware’s “logique” is critical for holding the “de construction” parts of this kit in place.

« Boulon à bride hexagonale’ (Q1840612F6) – Quantité 8: C'est le “de construction” logique. These high-tensile bolts are used to mount the *steel* ‘Guide Rails’ (Assemblée 684, MSU 1 & 4) that the ‘Glass Runnels’ (MSU 3) snap into.

‘Combination screw’ (Q2360616F6) – Quantité 12: C'est le “anti-vibration” logique. These screws, with their captive lock washers, are used to secure the ‘Rain Deflector’ (MSU 6) and the ‘Inner Sealing Strip’ (MSU 2) to their mounting points, ensuring a rattle-free fit.
