Compresseur de climatisation FAW J6P: 5 Pièces critiques pour un confort de cabine impeccable

Welcome to this expert deconstruction of the Compresseur de climatisation FAW J6P (Ensemble principal P/N 8103020-70A). C'est le “comfort core” and primary “refrigerant pump” Pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau.

This component is a “Assemblage logique” de 5 critical parts. C'est “logique” is to convert rotational power from the engine’s accessory belt into high-pressure refrigerant, qui est le “lifeblood” of the cab’s A/C system.

Le “Parasitic Load Logic” is the key to this Compresseur de climatisation FAW J6P. This is the single *largest* “parasitic load” in the engine’s accessory drive system. It is driven by the ‘Multi-groove belt’ (P/N 1023021-36D) but features an “Electromagnetic Clutch Logic.” Ce “embrayage” allows the compressor’s pulley to “free-spin” 99% of the time, creating almost no drag on the engine. When the driver presses the A/C button, this clutch “slams” shut, placing an *instant* 10-15 horsepower load on the engine. Ce “shock load” is what the ‘Automatic Tensioner’ (P/N 1023010-36D) is designed to handle.

This technical guide is an essential resource for chassis technicians, fleet maintenance managers, et spécialistes des pièces détachées. We will deconstruct the entire 5-component-type group. Nous analyserons le “Refrigerant Compression Logic” (the main compressor assembly itself), le “Structural Support Logic” (the anti-vibration bracket), et le “Critical Fastener Logic” (the high-tensile hardware) that mounts the Compresseur de climatisation FAW J6P to the engine.

Cœur 1: Le “Compression & Embrayage” Logique (Composant 1)

This component is the main assembly and the functional “cœur” of the entire cab comfort system. Le Compresseur de climatisation FAW J6P est un complexe, high-pressure pump.

1. Composant: ‘A/C compressor assy’ (8103020-70UN)
Ce (Comp 1) is the complete assembly. C'est “Refrigerant Logic” c'est être un “positive displacement” pompe. It sucks in *low-pressure, gaseous* refrigerant (like R134a) de la “evaporator” (the cold part in the dashboard). Intérieurement, it uses a “Wobble Plate” ou “Swash Plate” logique. Le “logique” is that the engine’s belt spins a pulley, which turns a central shaft. This shaft has a “wobble plate” mounted at an angle. As this plate “wobbles,” it drives a series of 5 ou 7 tiny “pistons” back and forth in their cylinders, compressing the refrigerant gas.

Ce “Logique de compression” turns the low-pressure gas into a *high-pressure, high-temperature* (superheated) gaz. Ce “hot gas” is then sent to the “condenseur” (the radiator at the front of the truck) where it releases its heat and turns back into a liquid, completing the cycle. The internal components of the Compresseur de climatisation FAW J6P are lubricated by a special “PAG oil” that circulates *with* the refrigerant, so a refrigerant leak is also an *oil leak* for the compressor.

2. Le “Electromagnetic Clutch Logic” (Internal to Comp 1)
C'est le “Interface Logic” pour le Compresseur de climatisation FAW J6P. The pulley on the front of the compressor is not directly connected to the internal shaft. Il “free-spins” on its own bearing. Ce “logique” means that when the A/C is off, the compressor is 100% disengaged and creates zero “parasitic” load on the engine.

When the driver presses the A/C button, un “electromagnet” is energized. This powerful magnet “tire” un “clutch plate” outwards, “slamming” it against the spinning pulley. Ce “Clutch Logic” is what locks the pulley to the compressor’s internal shaft, engaging the pump. Ce “slam” ou “shock load” is the most demanding event for the engine’s serpentine belt, and the *reason* a heavy-duty ‘Automatic tensioner’ is required for the Compresseur de climatisation FAW J6P to function without squealing or breaking the belt.

Cœur 2: Le “Structural Support” Logique (Composant 2)

Ce composant “logique” is to provide a rigid, perfectly aligned, and vibration-proof foundation for the Compresseur de climatisation FAW J6P.

1. Composant: ‘Support – A/C compressor’ (8103061-70UN)
Ce (Comp 2) est le “Anti-Fatigue Logic.” Le Compresseur de climatisation FAW J6P (Comp 1) is a heavy component that also has internal oscillating pistons, creating its own vibration. It *cannot* be bolted directly to a thin “timing cover” or a weak point on the engine block. Ce “Soutien” est un véhicule robuste, cast-iron bracket. C'est “logique” is to bolt to the main ‘Front-end system support’ (P/N 1023011-36D) or directly to the engine block’s structural “bosses.” This provides a “Shock-Proof Foundation” that can withstand the “slam” of the clutch engaging and the constant, high-frequency vibrations from the engine.

Le “Logique d'alignement” is its second, equally critical function. The serpentine belt must run with perfect “parallel” alignement. This ‘Support’ is machined to *guarantee* that the Compresseur de climatisation FAW J6P pulley is on the exact same plane as the crankshaft pulley, alternator pulley, and water pump pulley. A misaligned compressor (from a bent or cracked bracket) volonté “marcher” the belt off the pulley or “shred” its edges in a matter of hours. This makes the ‘Support’ a precision-critical component.

Cœur 3: Le “Fastener & Serrage” Logique (Composants 3, 4, 5)

This final group’s “logique” is to provide the high-tensile “clamping force” required to hold the entire Compresseur de climatisation FAW J6P assembly in place against all operational forces.

1. Composants: ‘Hexagon head bolt’ (CQ15010110) & ‘Hexagon flange nut’ (CQ39610)
The list calls for two (2) boulons (Comp 3) and two (2) des noisettes (Comp 4). Ce “Through-Bolt Logic” is the strongest possible mounting method. Ce “logique” implies that the ‘Support’ support (Comp 2) is mounted to the *main* engine accessory bracket using two long “studs” ou “through-bolts” that are secured by these nuts. Ce “Noix & Boulon” system provides a massive, vibration-resistant clamping force.

2. Composant: « Boulon à bride hexagonale, coarse shank (modèle standard)’ (Q1841230)
The list calls for one (1) de ceux-ci (Comp 5). C'est le “Primary Compressor Mount Bolt.” C'est “logique” is to be the main fastener that passes *through* the Compresseur de climatisation FAW J6P (Comp 1) and threads *into* the ‘Support’ (Comp 2). Le “Flange Logic” is that the built-in washer provides a large friction surface that prevents the bolt from “marche” loose from vibration. Le “Coarse Shank Logic” means it is a high-strength bolt designed to withstand the “sheer force” (the side-to-side force) of the belt tension. These three sets of hardware are all that hold the heavy, high-load Compresseur de climatisation FAW J6P in place.
