Panneau de toit FAW J6P: Déconstruction 17 Pièces critiques pour un contrôle parfait du levier de vitesse

Welcome to this specialized deconstruction of the Panneau de toit FAW J6P, the top cover assembly for the CA10TA160M 10-speed transmission. This guide is for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau, analyser le 17 components that form the Panneau de toit FAW J6P, the critical interface between the driver’s shift lever and the gearbox’s internal rails.

Le Panneau de toit FAW J6P est le “Human-Machine Interface” de la boîte de vitesses. Its logic is to translate the driver’s “X-Y” (side-to-side and fore-aft) hand movements into a precise, isolated “Z” (downward) motion onto the correct shift rail. This assembly ensures smooth, precise gear selection and is the key to the entire shift-feel and interlock system.

Cœur 1: Le “De construction & Scellage” Logique (Le logement)

This group represents the foundational “châssis” of the entire shift lever mechanism. All other components in this list are mounted *inside* or *onto* this single part, le Panneau de toit FAW J6P.

1. Composant: ‘Top cover’ (1702211A703)
Ce (Comp 5) is the main ‘Top cover’, le Panneau de toit FAW J6P fonderie. C'est un véhicule robuste, complex component, precision-cast from iron or aluminum. Sa logique est triple:

Le Logique d'alignement est sa fonction la plus critique. Le Panneau de toit FAW J6P is machined with precise, parallel bores. These bores are the “tunnels” that support the ‘Shift shaft’ (Comp 11) and ‘Select gear arm’ (Comp 15), ensuring they move smoothly and engage the internal rails perfectly.

Le Logique d'étanchéité is its second function. This component acts as the final “roof” pour le “Upper Cover” assemblée, sealing the shift mechanism from the elements. It is sealed to the lower housing by the ‘Gasket’ (Comp 10).

2. Composant: 'Joint – capot supérieur’ (1702216-A7G)
Ce (Comp 10) is the main static seal. This precision-cut gasket sits between this Panneau de toit FAW J6P (Comp 5) and the ‘Upper Cover’ (from the previous breakdown, article 56). Its logic is to prevent high-temperature oil “éclabousser” from escaping the gearbox and to keep water/dirt *out* of the shift mechanism.

3. Composant: ‘Breather plug assy’ (1702240-A7G)
Ce (Comp 9) est le “poumon” of the entire gearbox. Ce Élément de connexion FAW J6P (as it is also a connector) threads into the Panneau de toit FAW J6P.

C'est Venting Logic est critique. As the gearbox heats up, the oil and air inside expand, creating positive pressure. This ‘Breather plug’ is a one-way valve that “exhales” this pressure. This prevents the pressure from building up and blowing out the main oil seals (comme Comp 3 et 8).

Cœur 2: Le “Shift” Logique (Fore-Aft Motion)

This group represents the components in the Panneau de toit FAW J6P that are responsible for the driver’s “pousser-tirer” (forward-and-backward) mouvement. C'est le “Y-axis” of the H-pattern, which engages the gear.

1. Composant: ‘Shift shaft & arm assy’ (1702220A703)
Ce (Comp 11) est le noyau “shift shaft.” The external “bras” of this assembly connects to the driver’s shift lever linkage. Le “arbre” portion slides fore-and-aft *inside* the bores of the Panneau de toit FAW J6P (Comp 5).

Le Logique d'actionnement is to transfer the “pousser/tirer” motion from the driver, down through the Panneau de toit FAW J6P, to the ‘Shift selector head’ (Comp 12).

2. Composant: ‘Shift selector head’ (1702231A703)
Ce (Comp 12) est le “finger” at the bottom of the ‘Shift shaft’ (Comp 11). Its logic is to be the single part that engages the “gates” on the shift rails (housed in the cover *below* this Panneau de toit FAW J6P). When the driver pushes forward, ce “tête” pushes the selected shift rail forward.

3. Le “Shift Shaft Bushing & Joint” Groupe (Comp 3, 4, 7, 8)
Ce groupe comprend: ‘Top cover oil seal assy – shift shaft’ (Comp 3 & 8) and ‘Sliding bush – capot supérieur’ (Comp 4 & 7).

Le Bushing Logic is for smooth operation. The two ‘Sliding bushes’ (Comp 4, 7) are low-friction liners pressed into the Panneau de toit FAW J6P (Comp 5). They allow the ‘Shift shaft’ (Comp 11) to slide back and forth with minimal effort and no metal-on-metal contact.

Le Dynamic Seal Logic is the job of the two ‘Oil seal assemblies’ (Comp 3, 8). These are critical *dynamic* seals. They are mounted in the Panneau de toit FAW J6P to prevent gearbox oil from “splashing” up the shift shaft and leaking out of the top of the transmission.

Cœur 3: Le “Sélectionner” Logique (Side-to-Side Motion)

This group represents the components in the Panneau de toit FAW J6P that handle the driver’s “side-to-side” mouvement. C'est le “X-axis” of the H-pattern, which *selects* which shift rail to engage.

1. Composant: ‘Select gear arm’ (1702241A703)
Ce (Comp 15) is the ‘Select gear arm’. This component is also connected to the driver’s shift lever linkage. Its logic is to *rotate* the ‘Shift shaft’ (Comp 11) along its long axis.

Ce Rotational Logic is what moves the ‘Shift selector head’ (Comp 12) from side-to-side. This action is what “selects” which shift rail (1/R., 2/3, ou 4/5) the ‘Shift selector head’ is aligned with, *before* the driver “shifts” (pushes/pulls) il. C'est le “selector” une partie du Panneau de toit FAW J6P mécanisme.

2. Le “Verrouillage de sécurité” Groupe (Comp 16, 17)
Ce groupe comprend: ‘Fastening screw’ (Comp 16) et « Ligne de verrouillage en fil d'acier’ (Comp 17).

Le Logique critique des fixations est leur fonction. The ‘Fastening screw’ (Comp 16) is what locks the ‘Select gear arm’ (Comp 15) to its shaft. Because this fastener is *inside* the Panneau de toit FAW J6P, it must *never* come loose.

The ‘Steel wire lock line’ (Comp 17) est un “sécurité intégrée” appareil. This wire is threaded through a hole in the head of the screw (Comp 16) and twisted, making it physically *impossible* for the screw to vibrate loose. Il s'agit d'un élément de sécurité essentiel du Panneau de toit FAW J6P assemblée.

Cœur 4: Le “Attache & Lien” Logique (Matériel)

This final group includes all the miscellaneous hardware that mounts the Panneau de toit FAW J6P to the gearbox and connects the external linkages.

1. Le “Mounting Bolt” Groupe (Comp 6, 13, 14)
Ce groupe comprend: « Boulon à bride hexagonale’ (Comp 6, Quantité 4), « Rondelle élastique’ (Comp 13, Quantité 1), and ‘Hexagon head bolt with guide neck’ (Comp 14, Quantité 1).

Le Logique de serrage est leur fonction. These are the main bolts that securely fasten the Panneau de toit FAW J6P (Comp 5) au “Upper Cover” (from the previous breakdown, article 56).

The ‘Flange bolts’ (Comp 6) are self-locking and resist vibration. The ‘Guide neck’ boulon (Comp 14) is a high-precision bolt, likely used at a critical alignment point, with a ‘Spring washer’ (Comp 13) to provide constant tension. These ensure the Panneau de toit FAW J6P remains rigid and oil-tight.

2. Le “Lien” Groupe (Comp 1, 2)
Ce groupe comprend: ‘Dust cover – capot supérieur’ (Comp 1, Quantité 2) and ‘Lever transmission type hose clamp’ (Comp 2).

Le Logique de protection is the job of the ‘Dust cover’ (Comp 1). These are flexible rubber “soufflet” ou “bottes” that slide over the external shift linkages (like the ‘Select gear arm’). They protect the pivot joints from dirt, sable, et de l'eau, which would quickly wear them out.

Le Logique de serrage of the ‘Hose clamp’ (Comp 2) is to securely fasten these ‘Dust covers’ (Comp 1) onto the linkages, ensuring a tight seal. These are essential for the long-term reliability of the Panneau de toit FAW J6P‘s external mechanism.
