Vilebrequin FAW J6P: 14 Pièces critiques pour une puissance de rotation parfaite

Bienvenue dans cette déconstruction experte du Vilebrequin FAW J6P, le “colonne vertébrale” du moteur pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau.

This is not a single part but a complete “Assemblage logique” de 14 composants, all engineered to perform one task: to convert the violent, linear force of six pistons into the smooth, continuous rotational power that moves the truck.

Le “logique” de la Vilebrequin FAW J6P (P/N 1005014-36D) is all about force-transfer and balance, making it the most critical component for engine reliability.

Le “Metallurgy Logic” de la Vilebrequin FAW J6P est sa caractéristique la plus importante. This is not a cast-iron component; it is drop-forged from a single billet of high-tensile steel. Ce “forged logic” is essential to withstand the two opposing forces that try to destroy it: le “compression” (the downward push of the combustion stroke) et le “tension” (the high-RPM “extensible” as it pulls the piston back up). The entire assembly, from the ‘Silicone oil damper’ at the front to the ‘Flywheel’ at the back, is a precisely balanced system designed to run for millions of cycles without failure.

Ce guide technique est une ressource essentielle pour les reconstructeurs de moteurs, techniciens d'atelier d'usinage, et gestionnaires de pièces de flotte. We will deconstruct the entire 14-component group into its four primary “logique” systèmes: le “Structural Core Logic” (the crankshaft itself), le “Front-End NVH & Logique de conduite” (the damper and pulley assembly), le “Rear-End Power Transfer Logic” (the flywheel assembly), et la critique “Internal Sealing & Gearing Logic.” Ceci est le guide complet du Vilebrequin FAW J6P.

Cœur 1: Le “Noyau structurel” Logique (Composant 6)

This component is the literal and functional “colonne vertébrale” of the entire rotating assembly.

1. Composant: ‘Crankshaft’ (1005014-36D / 1005014-36Base de données)
Ce (Comp 6) est le principal Vilebrequin FAW J6P. C'est “Forged Logic” means it is forged from a single, high-tensile steel billet to handle the “compression” et “tension” forces. C'est “Logique d'équilibrage” is in the massive, intégré “counterweights.” These are precisely weighted to cancel out the massive, oscillating forces of the six pistons, providing a smooth rotation and preventing the engine from shaking itself apart. C'est “Fluid Logic” is a network of internal oil galleries, drilled through the shaft. Oil is fed *in* via the main bearings and flows *out* through the “rod journals” to lubricate the connecting rod bearings. This internal lubrication is the lifeblood of the Vilebrequin FAW J6P.

Cœur 2: Le “Front-End NVH & Conduire” Logique (Comp 1, 2, 3, 4, 8)

This group of components bolts to the “nez” or front of the Vilebrequin FAW J6P. Its logic is to dampen vibration and drive the engine’s accessories.

1. Le “Amortissement NVH” Logique: ‘Silicone oil damper’ (1005190-36D) & « Boulon d'amortisseur’ (1005048K29D)
C'est le “harmonic damper” (Comp 3). C'est “logique” est critique: every combustion stroke *twists* the Vilebrequin FAW J6P slightly. C'est “torsional vibration.” This damper, which is a heavy steel ring floating in a layer of silicone oil, est “à l'écoute” to that exact frequency. It oscillates *out of phase* with the crank, absorbing the twisting energy and turning it into heat. Ce “logique d'amortissement” prevents the Vilebrequin FAW J6P from finding its resonant frequency and shattering. It is held on by six (6) ‘Damper bolts’ (Comp 1).

2. Le “Accessoire & Timing” Logique: (Comp 2, 4, 8)
The ‘Multi-groove belt pulley’ (Comp 2) bolts to the damper. C'est “logique” is to transfer the crank’s rotation to the serpentine belt, which drives the alternator, pompe à eau, et compresseur de climatisation. The ‘Crankshaft timing gear’ (Comp 8) is a toothed gear that drives the engine’s camshaft and/or injection pump, ensuring the valves and fuel are “chronométré” perfectly. The ‘Front oil seal’ (Comp 4) est le “dynamic seal logic,” a high-temperature rubber lip seal that rides on the front of the crank, keeping the oil inside the crankcase.

Cœur 3: Le “Rear-End Power Transfer” Logique (Comp 10, 11, 12, 13)

This group bolts to the rear flange of the Vilebrequin FAW J6P. Its logic is to store rotational energy and provide the mounting surface for the clutch and transmission.

1. Composant: 'Volant’ (1005121-630-0000)
Ce (Comp 12) est le “Rotational Battery.” C'est “Logique d'inertie” is its massive weight. Each combustion stroke is a single “punch.” The flywheel’s mass “stores” this energy, smoothing out the pulses into the continuous, usable rotation needed to move the truck. C'est “Logique d'embrayage” is its large, perfectly flat, machined “surface de friction.” Le disque d'embrayage appuie contre cette surface, which is how 100% de la puissance du moteur est transférée à la transmission. The ‘Thrust ring’ (Comp 11) is likely part of this flywheel interface.

2. Le “Attache & Alignement” Logique: (Comp 10, 13)
The ‘Positioning key’ (Comp 10) is a small steel key. C'est “logique” is to ensure the flywheel can only be installed onto the Vilebrequin FAW J6P in *one* exact position. This is critical for timing and balance. The ‘Flywheel bolts’ (Comp 13) sont les “Logique critique des fixations.” La liste réclame 10 boulons à haute résistance. These are almost always “Couple/rendement” (ATS) bolts that are *single-use* and must be replaced to prevent the flywheel from detaching under load.

Cœur 4: Le “Internal Sealing & Gearing” Logique (Comp 7, 9, 14)

This final group consists of the serviceable components that are either pressed onto or housed within the Vilebrequin FAW J6P.

1. Composant: «Pignon d'entraînement de pompe à huile – vilebrequin’ (1005039-36D)
Ce (Comp 7) est le “Logique vitale.” This gear is pressed onto the Vilebrequin FAW J6P, usually near the front. Its sole purpose is to drive the engine’s oil pump. If this gear fails, the oil pump stops, and the entire engine (y compris le Vilebrequin FAW J6P lui-même) will be destroyed from oil starvation in minutes.

2. Composant: 'Joint d'huile arrière’ (1005060-29D)
Ce (Comp 9) est le “Logique du sceau principal.” C'est un grand diamètre, high-temperature rubber seal that is pressed into the engine block or a seal housing. C'est “étanchéité dynamique” logic allows the Vilebrequin FAW J6P to spin freely while preventing oil from leaking out of the “principal arrière” du moteur. A failure here results in a large, hard-to-fix oil leak between the engine and transmission.

3. Composant: « Roulement à billes 60305-2RS’ (GB/T 276-1994)
Ce (Comp 14) est le “Pilot Bearing Logic.” Ce petit, sealed bearing is pressed into a recess in the *very end* of the Vilebrequin FAW J6P. C'est “logique” is to support the “nez” of the transmission’s input shaft. This ensures the transmission shaft stays perfectly centered with the crankshaft. A failed pilot bearing will cause a grinding noise when the clutch is pressed and make shifting gears very difficult.
