FAW J6P Deuxième Axe: Déconstruction 14 Pièces critiques pour une sortie d'engrenage impeccable

Bienvenue dans cette déconstruction critique du FAW J6P Deuxième Axe, also known as the mainshaft, for the CA10TA160M gearbox in the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This technical guide analyzes the 14 components that make up the complete FAW J6P Deuxième Axe assemblée, which is the heart of the transmission’s “sortir” logique.

Le FAW J6P Deuxième Axe is the output shaft of the main 5-speed gear case. Its logic is to hold all the “conduit” engrenages (1st-4th, Inverse) and the synchronizer sleeves that lock them. The integrity of this one shaft and its components is directly responsible for every gear shift and all power delivery to the wheels.

Cœur 1: Le “Arbre & Ensemble d'engrenages” Logique (The FAW J6P Second Axis)

Ce groupe représente le “colonne vertébrale” et le “driven gears” of the main gearbox. Le FAW J6P Deuxième Axe is the component that the driver is “de liaison” to when they select a gear.

1. Composant: ‘Second axis’ (1701301-A7G)
Ce (Comp 1) is the ‘Second axis’ lui-même, the mainshaft. This is a long, heavy-duty shaft, precision-machined from hardened steel with multiple steps and grooves. Its logic is to act as the central “colonne vertébrale” for all the main driven gears.

Le Logique d'alignement est critique. L'avant “conseil” de ceci FAW J6P Deuxième Axe is supported by the pilot bushing *inside* the ‘First Axis’ (arbre d'entrée). The rear of the shaft is supported by a large bearing in the back of the gearbox case. This two-point support keeps it perfectly concentric.

Le Gear Carrier Logic is its main function. Le “mesures” on the shaft are smooth, hardened surfaces on which all the free-spinning gears (Comp 5, 10, 12, 13, 14) ride, usually on needle bearings. Le “cannelé” sections are where the ‘Sliding gear sleeves’ (Comp 8) sont montés, which are the parts that lock the gears to the FAW J6P Deuxième Axe.

2. The Driven Gears (Comp 5, 10, 12, 13, 14)
Ce groupe comprend: ‘Reverse gear’ (Comp 5), ‘First gear’ (Comp 10), ‘Second gear’ (Comp 12), ‘Third gear’ (Comp 13), and ‘Fourth gear’ (Comp 14).

Le Freewheeling Logic is the key concept. All five of these “driven gears” are in *constant mesh* with their respective drive gears on the countershaft. Cependant, they are *not* fixed to the FAW J6P Deuxième Axe. They all spin freely on the shaft at different speeds.

Lorsque le conducteur sélectionne “3ème vitesse,” they are *not* moving the gear itself. They are moving a ‘Sliding gear sleeve’ (Comp 8) à “verrouillage” the ‘Third gear’ (Comp 13) au FAW J6P Deuxième Axe. At that moment, power flows from the countershaft, through the now-locked Comp 13, and out through the FAW J6P Deuxième Axe.

Cœur 2: Le “Fiançailles” Logique (Manches & Keys)

This group contains the components that perform the physical “verrouillage” of the gears to the FAW J6P Deuxième Axe. This is the core of the synchronizer assembly.

1. Composant: ‘Sliding gear sleeve’ (1701316-A7G) – Quantité 3
Ce (Comp 8) is the ‘Sliding gear sleeve’. There are three of them, likely for the 1-2 changement, le 3-4 changement, and the Reverse shift. This is the component that the driver’s shift fork physically slides back and forth on the splines of the FAW J6P Deuxième Axe.

Le Logique de verrouillage est sa fonction. The ‘sleeve’ has internal splines that match the FAW J6P Deuxième Axe. When the driver shifts, this sleeve slides over a set of external “dents de chien” on the side of the target gear (Par exemple, ‘First gear’, Comp 10). This creates a solid, positive, non-slip lock, making the gear and the shaft spin as one unit.

2. Le “Detent Key” Groupe (Comp 3, 4)
Ce groupe comprend: ‘Three-sided key’ (Comp 3) and ‘Snap ring – clé à trois côtés’ (Comp 4). C'est le “synchronizer key” ou “strut.”

Le Detent Logic is the function of the ‘Three-sided key’ (Comp 3). This small key sits in a groove in the synchronizer hub (which is splined to the FAW J6P Deuxième Axe) and is pushed outwards by a spring (non répertorié) into a groove *inside* the ‘Sliding gear sleeve’ (Comp 8).

This key is what creates the “neutre” position for the sleeve. Il fournit le “instantané” et “cliquez” feeling in the gear lever. The ‘Snap ring’ (Comp 4) is a small retainer that holds this key in its slot, preventing it from falling out during assembly or operation.

Cœur 3: Le “Positionnement & Entretoise” Logique (Rondelles)

This final group of components is arguably the most critical for a long-lasting, calme FAW J6P Deuxième Axe. Their logic is to precisely control the “terminer la lecture” and spacing of all the spinning gears.

1. Le “Reverse Gear” Spacer Group (Comp 6, 7)
Ce groupe comprend: ‘Positioning washer – marche arrière’ (Comp 6) and ‘Limiting washer – marche arrière’ (Comp 7). These are the dedicated spacers for the ‘Reverse gear’ (Comp 5).

Le Thrust Logic est leur fonction. The ‘Positioning washer’ (Comp 6) likely sits behind the gear, setting its base position on the FAW J6P Deuxième Axe. The ‘Limiting washer’ (Comp 7) sits on the other side. Ensemble, these washers create a “sandwich” that controls the gear’s “axial play” (fore-and-aft movement). This precise spacing is essential for proper engagement with the reverse idler gear and the synchronizer sleeve.

2. Le “Main Gear” Spacer Group (Comp 9, 11)
Ce groupe comprend: ‘Limiting washer – engrenage’ (Comp 9, Quantité 4) and ‘Inter-shaft limiting washer’ (Comp 11, Quantité 2).

Le Spacer Logic is the job of the ‘Limiting washers’ (Comp 9). These four washers are the “espaceurs” that sit on the FAW J6P Deuxième Axe *between* the free-spinning gears (Par exemple, between 1st and 2nd, 2nd and 3rd, etc.). They prevent the hardened gears from rubbing directly against each other, which would generate immense heat and destructive metal particles.

Le Thrust Bearing Logic is the job of the ‘Inter-shaft limiting washers’ (Comp 11). These are likely the main “rondelles de butée” pour l'ensemble des engrenages, located at the front and back of the gear stack. They absorb the massive axial forces generated by the helical-cut gears, protecting the FAW J6P Deuxième Axe bearings from being destroyed.

3. Composant: ‘Spring cylindrical pin’ (Q5280310)
Ce (Comp 2) is a ‘Spring cylindrical pin’, également connu sous le nom de “roll pin.” C'est Logique de verrouillage is to act as a secure, vibration-proof fastener. It is likely used to lock the main shift rail (which moves the forks) en place, or to secure a synchronizer hub (which holds Comp 3) au FAW J6P Deuxième Axe, preventing it from rotating or sliding.
