Support FAW J6P: Déconstruction 10 Pièces critiques pour un support d’embrayage impeccable

Bienvenue dans cette déconstruction critique du Support FAW J6P and clutch fork assembly. This system is a core component for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck’s manual transmission. This guide is for technicians, analyzing the 10 components that create the complete Support FAW J6P and lever system, which is essential for clutch actuation.

Le Support FAW J6P est le “fulcrum” of the entire clutch control mechanism. Its logic is to provide a rock-solid, stationary anchor point for the release fork’s pivot shaft. This component must absorb 100% of the force from the clutch booster, allowing the fork to multiply that force and disengage the heavy-duty clutch.

Cœur 1: Le “Structural Anchor” Logique (The FAW J6P Bracket)

This group represents the single most important “stationary” component in the assembly. Le Support FAW J6P is the foundation upon which the entire lever system is built.

1. Composant: ‘Release fork bracket’ (1602421A70A)
Ce (Comp 10) est le Support FAW J6P lui-même. This is a heavy-duty, high-strength component, likely cast from iron or steel. It is designed with a thick mounting flange and a precisely-bored “tunnel” for the pivot shaft.

Le Rigidity Logic is its core purpose. Le Support FAW J6P is bolted directly to a machined boss on the gearbox or clutch housing. It must be completely rigid and inflexible. Il agit comme le “fulcrum” for the ‘Release fork’ (Comp 2).

Any flex in this Support FAW J6P would be disastrous. It would mean that when the clutch booster applies force, the bracket would bend *before* the clutch disengages. This would waste energy, result in a “spongy” pédale, and cause incomplete clutch disengagement, leading to severe gear grind and transmission damage.

2. Le “Montage” Groupe (Comp 4, 5)
This group includes: « Boulon à bride hexagonale (for FAW gearbox)’ (Comp 4) and ‘Hexagon flange bolt’ (Comp 5). These are the two high-tensile bolts that secure the Support FAW J6P (Comp 10) to the transmission housing.

Le Flange Bolt Logic is a vibration-resistant design. Le “bride” is a built-in, non-spinning washer. This wide face distributes the clamping load and, more importantly, provides a much larger “friction face” that resists vibrational loosening far better than a standard bolt. This is essential for a component like the Support FAW J6P, which is subject to constant, high-frequency engine vibration.

Cœur 2: Le “Levier & Pivot” Logique (The Fork Assembly)

Ce groupe représente le “moving parts” that mount *onto* the Support FAW J6P. This is the lever system that does the actual “work” of actuating the clutch.

1. Composant: ‘Release fork – embrayage’ (1602416A70A)
Ce (Comp 2) est le “Clutch Release Fork.” This is the large lever arm. Its logic is to pivot on the shaft (Comp 3) that is held by the Support FAW J6P (Comp 10).

Le Force Multiplication Logic est sa fonction. It is a Class 1 Levier. The clutch booster pushes on the “short end” of the fork (at the ‘Spherical bearing’, Comp 9). This causes the “long end” (the tines) to move a greater distance in the opposite direction, pulling the release bearing and disengaging the clutch. This entire action is anchored by the Support FAW J6P.

2. Composant: ‘Release fork shaft’ (1602422A70A)
Ce (Comp 3) est le “essieu” ou “pivot pin.” This hardened steel shaft passes *through* the bore of the Support FAW J6P (Comp 10) and also through the pivot hole on the ‘Release fork’ (Comp 2).

Le Pivot Logic est sa fonction. It provides a smooth, low-friction surface for the fork to pivot on. It is held in place by ‘Spring circlips’ (Comp 1) and sealed by ‘Sealing gaskets’ (Comp 7). Le Support FAW J6P is what gives this shaft its rigid, stationary position.

Cœur 3: Le “Articulation & Saisir” Logique (The Bearing)

This component is the crucial “articulation” that connects the linear “push” of the clutch booster to the pivoting “arc” of the release fork. It is a key part of the Support FAW J6P‘s lever system.

1. Composant: ‘Radial spherical plain bearing’ (GE25ES)
Ce (Comp 9) est le “saisir” palier. This is not a roller or ball bearing; c'est un “spherical” palier, which is essentially a precision-machined “ball” (inner ring) inside a “douille” (outer ring).

Le Articulation Logic is its critical function. This bearing (Comp 9) is pressed into the “saisir” eyelet of the ‘Release fork’ (Comp 2). The pin from the clutch booster’s push-rod then passes through the inner “ball” of this bearing.

This design allows the clutch booster to push in a straight line, while the release fork (anchored by the Support FAW J6P) swings in a slight arc. Ce “spherical” bearing allows for this misalignment, preventing the linkage from binding, reducing wear, and ensuring a smooth, low-effort pedal feel for the driver.

It is held in place inside the fork’s eyelet by a ‘Spring circlip for hole’ (Comp 8), making it a replaceable service item for the Support FAW J6P assemblée.

Cœur 4: Le “Scellage & Positionnement” Logique (Matériel)

This final group contains all the supporting hardware that completes the Support FAW J6P assemblée, sealing it from the elements and precisely positioning the components.

1. Le “Scellage” Groupe (Comp 7)
This group includes: ‘Sealing gasket’ (Comp 7, Quantité 2).

Le Logique d'étanchéité is the job of these two ‘Sealing gaskets’. These are placed on the ends of the ‘Release fork shaft’ (Comp 3) where it passes through the ‘Release fork bracket’ (Comp 10) and the clutch housing.

They are critical “static seals” that prevent high-temperature gear oil from leaking *out* of the gearbox, et, just as importantly, Empêcher l'eau, road salt, and dirt from getting *in* and seizing the pivot shaft. Cela garantit la Support FAW J6P and fork pivot smoothly for the life of the clutch.

2. Le “Positionnement” Groupe (Comp 1, 6, 8)
This group includes: ‘Spring circlip for shaft’ (Comp 1, Quantité 2), ‘Spacer’ (Comp 6, Quantité 2), and ‘Spring circlip for hole’ (Comp 8, Quantité 2).

Le Locking Logic is the function of the “circlips” (anneaux d'arrêt). The ‘Shaft circlips’ (Comp 1) snap into grooves on the ‘Shaft’ (Comp 3) to prevent it from sliding out of the Support FAW J6P. The ‘Hole circlips’ (Comp 8) snap into grooves in the fork’s eyelet to lock the ‘Spherical bearing’ (Comp 9) in place.

Le Positioning Logic is the job of the ‘Spacers’ (Comp 6). These spacers are used to precisely position the ‘Release fork’ (Comp 2) on its shaft (Comp 3), controlling any “axial” (side-to-side) movement. This ensures the fork’s tines remain perfectly centered on the release bearing, which is critical for the Support FAW J6P système.
