Welcome to this essential teardown of the Protetor de câmbio FAW J6P para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. This is not just a piece of trim; it is a critical interface and storage module. Este guia detalha o 3 core components that form the complete assembly for flawless service.
O Protetor de câmbio FAW J6P is a multi-function component that is central to the cab’s interior. It serves several crucial functions: it acts as a protective housing for the gearshift linkage, it provides vital sound and thermal insulation from the transmission tunnel, and it integrates essential, at-hand storage for the driver.
In the high-vibration environment of a CA3250P66K2L1T1E dump truck, a component like this must be engineered for extreme durability. A poorly designed guard will rattle, squeak, and transmit excessive heat and noise into the cab, leading to driver fatigue and complaints. This deconstruction will analyze the main guard (5305011-B27) and its integrated storage box (5305021-B27).
We will explore the logic behind its material selection (typically high-impact, textured PC-ABS), its structural mounting points, and the way its components are assembled. Para um técnico, understanding the Protetor de câmbio FAW J6P is key to performing interior service, diagnosing noise, vibração, e dureza (Nvh) problemas, or replacing damaged parts correctly.
This is the largest component and the foundation of the Protetor de câmbio FAW J6P. It forms the visible, estética “console” that surrounds the gear lever.
1. Componente: ‘Gearshift Guard’ (5305011-B27) – Quantidade 1
Esse (Marca 1) is the main structural housing. É um grande, complexo, injection-molded part that is precisely shaped to fit the cab’s floor panel and the lower dashboard.
A Lógica Material: This guard is not made of simple, flimsy plastic. It is molded from an engineered thermoplastic, typically a PC-ABS (Policarbonato / Acrilonitrila Butadieno Estireno) mistura. This material is chosen for its superior combination of properties: high impact strength (to resist cracking from boots or tools), high-temperature resistance (to withstand heat from the transmission tunnel), and UV stability (to prevent fading).
The Acoustic Logic: A primary, unseen function of the Protetor de câmbio FAW J6P is noise, vibração, e dureza (Nvh) controlar. The large surface area of the guard acts as an acoustic barrier. It is often backed with a layer of sound-deadening felt or foam (não listado, but part of the assembly) to absorb and block transmission gear whine and road noise from entering the cab.
A Lógica Térmica: The transmission tunnel on a heavy-duty truck can become extremely hot. Esse Protetor de câmbio FAW J6P acts as a heat shield, protecting the driver’s legs from radiant heat and helping the climate control system operate more efficiently.
The Aesthetic Logic: This component is a major part of the cab’s interior design. The surface is given a “technical grain” or texture (a process done inside the injection mold) that makes it resistant to scratches, scuffs, and fingerprints. This texture also reduces glare, which is a key safety consideration.
A lógica do serviço: This main guard is the part that takes the most abuse. It is often cracked by heavy objects or broken during dashboard service. A technician replacing the 5305011-B27 must carefully disconnect the storage box (Essencial 2) and any underlying electrical connectors (like the Hi/Lo range switch) before unbolting the main guard from the floor.
This component is a sub-assembly that is integrated directly into the main guard, fornecendo essencial, at-hand storage for the driver.
1. Componente: ‘Gearshift Guard Storage Box’ (5305021-B27) – Quantidade 1
Esse (Marca 2) is the storage box module. A nota “(配备储物盒)” ou “with Storage Box” confirms this is a key feature of the Protetor de câmbio FAW J6P. This box is typically mounted in the rear section of the main guard, accessible to the driver.
The Ergonomic Logic: This box is designed for “at-a-glance” utility. It provides a convenient, secure place for the driver to store essential items like logbooks, pens, keys, or a phone, preventing them from sliding around the cab.
The Construction Logic: This box is molded from the same durable PC-ABS material as the main Protetor de câmbio FAW J6P to ensure a perfect color and texture match. It is often designed with a non-slip rubber mat at the bottom to prevent items from rattling.
A Lógica de Integração: This component is not just glued in; it is designed to be mechanically fastened *to* the main guard (Essencial 1). It uses tabs, clipes, or its own set of small screws (not detailed in this diagram) to create a single, solid assembly. This two-piece construction (guard + caixa) is often simpler and stronger to manufacture than molding one, extremely complex part.
A lógica do serviço: A common failure is a cracked storage box, or the box itself coming loose from the main guard. A technician would service this by first removing the entire Protetor de câmbio FAW J6P assembly from the floor, then turning it over to access the fasteners that secure this storage box (5305021-B27) to the main guard (5305011-B27).
These are the critical fasteners that secure the entire Protetor de câmbio FAW J6P conjunto (Essencial 1 e 2) to the cab’s floor panel or transmission tunnel.
1. Componente: 'Parafuso combinado de cabeça panela com recesso cruzado’ (Q2360616F6) – Quantidade 3
Esse (Marca 3) is a set of three specific, high-reliability screws. The small quantity suggests they are for key structural mounting points, supplemented by hidden clips.
The Combination Screw Logic: The name ‘Combination Screw’ (组合螺钉) é crítico. It means each screw (Q2360616F6) has a pre-installed, arruela cativa (likely a spring lock washer and a flat washer). This is a non-negotiable feature for a high-vibration environment.
This design ensures that the locking washer is present every time and exerts constant tension. This tension prevents the Protetor de câmbio FAW J6P de vibrar solto, which is the number one cause of interior squeaks and rattles.
A lógica principal: “Cabeça de panela com recesso cruzado” (十字槽平圆头) specifies a Phillips drive with a low-profile, wide head. This pan head distributes the clamping load over a wider area of the plastic guard, preventing the screw from cracking the mounting boss or pulling through the hole.
A lógica do serviço: When a driver reports a “solto” ou “chocalho” Protetor de câmbio FAW J6P, a technician’s first action is to locate and check the torque on these three screws. They are often hidden under small cosmetic caps or beneath the storage box’s rubber mat. They must be tight, mas não com torque excessivo, as this could strip the floor-pan threads.
