Filtre fin à carburant FAW J6P: Déconstruction 4 Pièces critiques pour une protection HPCR absolue

Bienvenue dans cette déconstruction experte du Filtre fin à carburant FAW J6P (Main Assy P/N 1117010-73D). C'est le “polissage” filter for the FAW Jiefang CA3250P66K2L1T1E 6×4 moteur du camion à benne basculante.

This is not the primary fuel filter/water separator. This is the *final*, haute efficacité “Assemblage logique” that provides the last line of defense for the engine’s most expensive components.

Le “logique” de ceci Filtre fin à carburant FAW J6P est “Absolute Purity.” Its sole function is to remove microscopic particulate matter (down to 2-5 microns) that the primary filter cannot, protecting the high-pressure pump and injectors from abrasive wear.

Le “Logique de protection HPCR” est la clé de cela Filtre fin à carburant FAW J6P. Un Common Rail haute pression (Hpcr) système (like the one on this FAW engine) operates with internal tolerances measured in *microns*. The injectors and high-pressure pump are lubricated *only* by the diesel fuel itself. A single particle of silica (saleté) or metal (from wear) that is larger than 5 microns will instantly “score” the injector needle or pump piston, leading to a catastrophic, multi-thousand-dollar failure. Ce “filtre fin” est le “gatekeeper” that ensures this *never* happens.

This technical guide is an essential resource for engine technicians, responsables de l'entretien de la flotte, et spécialistes des pièces détachées. We will deconstruct the entire 4-component-type group of the Filtre fin à carburant FAW J6P. Nous analyserons le “Absolute Filtration Logic” (the replaceable spin-on elements), le “Flow & Logique d'interface” (the main filter base), le “Logique de soutien structurel” (le support anti-vibration), et le “Scellage & Logique de fixation” that holds the assembly together and ensures a leak-proof seal.

Cœur 1: Le “Absolute Filtration” Logique (Component 1117050-73D)

C'est le “fonctionnement” composante du Filtre fin à carburant FAW J6P assemblée. This is the replaceable cartridge that does the actual cleaning.

1. Composant: ‘Spin-on diesel filter element assy’ (1117050-73D)
La liste en appelle à deux (2) de ceux-ci “spin-on” cartridges, which are part of the main ‘Fuel fine filter assy’ (1117010-73D). Ce “Dual Filter Logic” is a high-capacity design. The fuel likely flows in “parallèle” (splitting between both filters) ou “in-series” (passing through one, then the other) for multi-stage filtration.

Le “Micro-Filtration Logic” is what defines this component. Une norme “primary” filter/water separator might filter down to 30 microns. Ce Filtre fin à carburant FAW J6P est un “absolute” filtre, meaning its media (often a synthetic, multicouche, high-density composite) is rated to stop *99.9%* of all particles 2 à 5 microns in size. Ce “Absolute Logic” is the *only* thing that protects the micron-level tolerances of the HPCR injectors from being destroyed by abrasive “silt” (saleté fine) or metal particles.

Le “Logique de service” de ceci Filtre fin à carburant FAW J6P est-ce que c'est “spin-on” conception. The entire cartridge (housing and media) est un célibataire, disposable unit. This ensures that a technician cannot accidentally introduce dirt into the “faire le ménage” side of the housing during a filter change, which is a major risk with cartridge-style (drop-in) filtres.

Cœur 2: Le “Logement & Flow” Logique (Components 1117020-53D, 1117038-60D)

This group forms the “docking station” for the filter elements and manages the flow of fuel in and out of the Filtre fin à carburant FAW J6P.

1. Composant: ‘Fuel fine filter base assy’ (1117020-53D)
Ce composant (part of Comp 1) est le “Fluid Path Logic.” C'est un véhicule robuste, cast-aluminum housing. C'est “logique” is to provide all the necessary ports: un “sale” inlet port (from the primary filter/tank), two threaded “docks” for the spin-on filters (Comp 1117050-73D), et un “faire le ménage” outlet port (which feeds the high-pressure pump). This base is the central “collecteur” that directs the flow of fuel through the Filtre fin à carburant FAW J6P.

2. Composant: ‘Hollow bolt’ (1117038-60D)
La liste en appelle à deux (2) de ceux-ci “hollow bolts” (banjo bolts). C'est le “Fluid Interface Logic.” These bolts are *how* the fuel gets in and out of the ‘Filter base’ (Comp 1). A fuel line “banjo” fitting slides over the bolt, and the bolt is then threaded into the base. Le “hollow” “logique” (a hole through the center and a cross-drilled hole) allows fuel to flow *through* the bolt itself.

3. Composant: 'Joint’ (CQ72316T5)
La liste en appelle à quatre (4) de ceux-ci (Comp 1). C'est le “High-Pressure Sealing Logic” for the hollow bolts. Ce sont “rondelles d'écrasement” (likely copper or aluminum). Deux (2) gaskets are used *per bolt* (one on top, one on the bottom of the banjo fitting). Leur “logique” is to deform when the hollow bolt is tightened, creating a perfect, leak-proof, diesel-resistant seal. Re-using these washers will almost certainly result in a fuel leak, which is a major fire hazard.

Cœur 3: Le “Soutien structurel” Logique (Composant 3)

Ce composant “logique” is to protect the entire Filtre fin à carburant FAW J6P assembly from self-destruction via engine vibration.

1. Composant: ‘Fuel fine filter support’ (1117121-59D)
Ce (Comp 3) est le “Logique anti-vibration.” A heavy filter assembly (like this dual-canister Filtre fin à carburant FAW J6P), full of fuel, cannot just “hang” off the engine block by its aluminum housing. The intense vibration of a heavy-duty diesel engine would cause the aluminum base (Comp 1) à “fatigue” and crack in a very short time, provoquant une fuite de carburant massive.

Le “logique” de ceci “soutien” bracket is to act as a heavy-duty “brace.” It bolts to the ‘Filter base’ (Comp 1) and *also* to a rigid point on the engine block. Ce “triangulation” “logique” creates a robust, résistant aux vibrations “fondation” qui contient la totalité Filtre fin à carburant FAW J6P assembly securely in place, preventing cracks and leaks. Piston

Cœur 4: Le “Attache” Logique (Composants 2, 4)

Ce dernier groupe “logique” est de fournir le “force de serrage” qui tient le Filtre fin à carburant FAW J6P assembly together and to the engine.

1. Composants: « Boulon combiné’ (CQ1461030) & (CQ1420820)
The list calls for a total of four (4) of these ‘Combination bolts’ (Comp 2 & 4). Ce sont les “Logique de montage” attaches.

Le “Combination Logic” means these are bolts with a pre-attached, captif “rondelle” (usually a spring/lock washer). Ce “logique” is superior for two reasons: 1) It’s a “facilité d'entretien” logique, as the technician cannot forget or drop the washer. 2) C'est un “résistant aux vibrations” logique. The spring washer provides a constant “précharger” ou “tension,” which prevents the bolt from “marche” loose under the engine’s constant vibration. These bolts are what secure the ‘Support’ (Comp 3) and ‘Filter base’ (Comp 1) au bloc moteur, complétant le Filtre fin à carburant FAW J6P installation.
