Juntas de puerta FAW y deflectores de lluvia: El 6 Secretos esenciales para un silencio, Seco, y cabina libre de plagas

Welcome to this in-depth guide on the Juntas de puerta FAW y deflectores de lluvia (Asamblea 687). este es el completo, 6-tipo de componente, “environmental logic” kit for the ‘FAW Front Door’ (Asamblea 683) on the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor. This assembly is a critical system with a “triple-threat” lógica: 1) to provide a 100% waterproof seal, 2) to eliminate wind noise (Nvh), y 3) to protect the driver from insects and road spray.

El “lógica” del Juntas de puerta FAW y deflectores de lluvia 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 (juntas), secondary seals (runnels), and tertiary accessories (deflectores, nets). This system works with the ‘Door Trim’ (Asamblea 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, y gerentes de repuestos. Deconstruiremos todo Juntas de puerta FAW y deflectores de lluvia kit into its 6 distinct Minimum Serviceable Unit (Universidad Estatal de Michigan) types. Analizaremos el “dual-sweep” logic of the window seals, el “baja fricción” logic of the runnels, y el “driver comfort” logic of the rain deflectors and insect nets.

Centro 1: El “aero & Weather” Lógica (MSU 1 & 6) (El “Más extenso” Módulo)

This group of MSUs from the Juntas de puerta FAW y deflectores de lluvia kit is the “first line of defense” against the elements and wind noise. It consists of the outer “squeegee” and the aerodynamic “visor.”

1. Universidad Estatal de Michigan 1: ‘Outer Window Sealing Strip’ (6103035-A01 / 6103040-A01)

Este es el “outer window sweep” o “dew wipe.” Es “lógica” 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, hielo, and dust off the glass. Este “lógica” es critico. 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.

Construcción: This MSU has a “dual-durometer” lógica. 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. Universidad Estatal de Michigan 6: ‘Front Door Rain Deflector’ (6101551BD04 / 6101552BD04)

Este es el “vent visor” o “wind deflector.” This is a key “driver comfort logic” component in the Juntas de puerta FAW y deflectores de lluvia kit.

Aero Logic (Ventilación): Es “lógica” 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.

NVH Logic (Buffeting): This MSU also solves “wind buffeting.” Driving at high speed with a window cracked open can create a painful, low-frequency “thumping” o “buffeting” sound as air is pressurized inside the cab. This deflector’s “lógica” es actuar como un “mercado,” smoothing the airflow past the opening and eliminating this noise.

Centro 2: El “Silent Seal” Lógica (MSU 2 & 3)

This group of MSUs from the Juntas de puerta FAW y deflectores de lluvia kit forms the “interno” seal, which is critical for NVH (Ruido, Vibración, Dureza) and sealing.

Universidad Estatal de Michigan 3: ‘Door Glass Runnel’ (6103051-A01 / 6103052-A01)

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

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

Universidad Estatal de Michigan 2: ‘Inner Window Port Sealing Strip’ (6102065BD04 / 6102070BD04)

Este es el “inner window sweep.” es el “twin” to MSU 1, but it mounts on the *inside* of the door, as part of the ‘Door Trim’ (685). Es “lógica” is the final “cosmetic” y “acoustic” seal. It hides the “brecha” between the trim panel and the glass, and its flocked lip provides a final, silent “anti-sonajero” buffer.

Centro 3: El “Pest & Escombros” Lógica (MSU 4 & 5)

This final group of MSUs in the Juntas de puerta FAW y deflectores de lluvia kit is a pure “driver comfort” y “regional” lógica.

Universidad Estatal de Michigan 5: ‘Front Door Insect Net’ (6103105BD04 / 6103110BD04)

Este es el “anti-insect” lógica. It is a custom-fit, tear-resistant mesh screen. Es “lógica” 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.

Universidad Estatal de Michigan 4: ‘Front Door Insect Net Hook Strip’ (6103113BD04)

Este es el “mounting logic” for the net. es el “gancho” side of a “hook-and-loop” (Velcro-style) sistema de sujeción. This adhesive-backed strip (Universidad Estatal de Michigan 4) is applied to the door frame. The net (Universidad Estatal de Michigan 5) has the “loop” side sewn onto its border. Este “lógica” allows the driver to install or remove the net in seconds, with no tools.

Centro 4: El “Instalación” Lógica (MSU 7 & 8)

El (implied) hardware for the Juntas de puerta FAW y deflectores de lluvia is listed in a related assembly (684). This hardware’s “lógica” is critical for holding the “estructural” parts of this kit in place.

«Perno de brida hexagonal’ (Q1840612F6) – Cantidad 8: Este es el “estructural” lógica. These high-tensile bolts are used to mount the *steel* ‘Guide Rails’ (Asamblea 684, MSU 1 & 4) that the ‘Glass Runnels’ (Universidad Estatal de Michigan 3) snap into.

‘Combination screw’ (Q2360616F6) – Cantidad 12: Este es el “antivibración” lógica. These screws, with their captive lock washers, are used to secure the ‘Rain Deflector’ (Universidad Estatal de Michigan 6) and the ‘Inner Sealing Strip’ (Universidad Estatal de Michigan 2) to their mounting points, ensuring a rattle-free fit.
