Volante FAW J6P: Desconstruindo 6 Peças críticas para transferência de energia perfeita

Bem-vindo a esta análise técnica definitiva do Volante FAW J6P (P/N 1005121-630-0000). Este é o “Rotational Battery” for the engine in the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando.

This component is not just a heavy disc; é um “Montagem Lógica” engineered to store and smooth out the engine’s power.

O “lógica” do Volante FAW J6P is to convert the violent, intermittent “punches” of combustion into the smooth, continuous torque needed to move the truck. It is also the primary interface for the vehicle’s clutch.

O “Lógica Dupla” disso Volante FAW J6P é sua característica mais importante. First is its “Inertia Logic.” A 6-cylinder diesel engine fires in violent, individual power strokes. The massive weight of the Volante FAW J6P absorbs this kinetic energy and uses inertia to keep the crankshaft spinning smoothly between these power pulses. Sem isso, the engine’s vibration would be uncontrollable. Second is its “Clutch Logic.” The flywheel is machined with a perfectly flat, resistente ao calor “friction surface.” The clutch disc presses against this surface, and this is the exact point where 100% of the engine’s power is transferred to the transmission. A warped or cracked Volante FAW J6P will destroy a clutch and make the truck undrivable.

This expert guide is an essential resource for transmission specialists, engine rebuilders, e gerentes de peças de frota. Desconstruiremos todo o grupo de componentes associado ao Volante FAW J6P. Iremos analisar o “Inertia & Clutch Logic” (the flywheel itself), o “Alinhamento & Interface Logic” (the positioning key and pilot bearing), o “Critical Fastener Logic” (the high-tensile TTY bolts), e o “Associated Sealing Logic” (the rear main seal).

Essencial 1: O “Inertia & Embreagem” Lógica (Componente 12)

This component is the main event. Its logic is to store energy and provide a friction surface for the clutch.

1. Componente: ‘Flywheel’ (1005121-630-0000)
Esse (Comp. 12) é o principal Volante FAW J6P. Isso é “Inertia Logic” comes from its massive weight, typically made from nodular cast iron. This weight acts as a “rotational battery,” storing the kinetic energy from each combustion “punch” and releasing it smoothly, which is what provides the engine with stable idle and smooth torque delivery. Without this mass, the engine would shake violently and stall.

O “Clutch Logic” is its secondary function. O apartamento, wide, machined face is the primary “friction surface” for the clutch disc. This surface must be perfectly flat (with a tolerance of thousandths of an inch) and durable enough to withstand the intense heat and friction from clutch engagement, especially in a heavy-duty dump truck application. The third “lógica” do Volante FAW J6P é o seu “Starter Logic.” The hardened “engrenagem anelar” on its outer edge is what the starter motor engages to turn the engine over. A missing or damaged tooth on this ring gear will prevent the engine from starting.

Essencial 2: O “Alinhamento & Interface” Lógica (Componentes 10, 14)

This group of small components has a critical “lógica” of ensuring perfect, micron-level alignment between the engine and the transmission.

1. Componente: ‘Positioning key – …volante’ (1005031-29D)
Esse (Comp. 10) é o “Rotational Alignment Logic.” A Volante FAW J6P is externally balanced *with* the crankshaft. It *must* be installed in the one, and only one, correct orientation. This small steel “chave” fits into a groove on the crankshaft flange and a matching slot in the Volante FAW J6P, making it impossible to install incorrectly. This logic is essential for a vibration-free engine.

2. Componente: ‘Ball bearing 60305-2RS’ (GB/T. 276-1994)
Esse (Comp. 14) é o “Transmission Interface Logic,” commonly known as the “pilot bearing.” Este pequeno, sealed bearing is pressed into a recess in the very center of the Volante FAW J6P (or the end of the crank). O “nariz” of the transmission’s input shaft rides inside it. Isso é “lógica” is to support the transmission shaft and keep it perfectly centered with the crankshaft’s centerline. A failed pilot bearing is a common cause of clutch failure, “moagem” noises when the clutch is pressed, and difficulty shifting gears.

Essencial 3: O “Fixador Crítico” Lógica (Componente 13)

This component’s logic is to provide the massive, unwavering clamping force required to hold the Volante FAW J6P to the crankshaft against all rotational forces.

1. Componente: ‘Flywheel bolt’ (1005071K29D)
The list calls for ten (10) of these critical bolts (Comp. 13). Estes não são hardware padrão. Deles “lógica” é “Critical Clamping Force.” They are engineered to handle the immense “sheer” force of transferring the engine’s full torque, assim como o “tração” force of the clutch clamping.

These are almost universally “Torque para rendimento” (TTY) parafusos. O “TTY Logic” é que eles são projetados para serem apertados até um ponto específico onde *se esticam permanentemente*. This stretching action turns the bolt into a high-tension spring, providing a perfectly consistent clamping force that will not loosen under vibration. This is why they are *single-use*. Once stretched, they are compromised and MUST be replaced every time the Volante FAW J6P is serviced. Re-using them is a critical error that can lead to the flywheel detaching from the engine—a catastrophic, transmission-destroying failure.

Essencial 4: O “Associated Sealing & Interface” Lógica (Comp. 9, 11)

This final group consists of the serviceable components that are part of the “mestre” crankshaft group but are directly related to the Volante FAW J6P instalação.

1. Componente: ‘Rear oil seal’ (1005060-29D)
Esse (Comp. 9) é o “Main Seal Logic.” É um diâmetro grande, high-temperature rubber seal that is pressed into the engine block or a seal housing *before* the Volante FAW J6P está instalado. The flywheel’s mounting flange (or a sleeve) spins inside this seal. Isso é “dynamic sealing” logic allows the crankshaft to spin freely while preventing oil from leaking out of the “rear main” do motor. A failure here is a very common and major oil leak that will contaminate the clutch, causing it to slip and fail.

2. Componente: ‘Thrust ring’ (1005122-29D)
Esse (Comp. 11) é o “Clutch Interface Logic.” This ring is likely a “shim” ou “thrust ring” that works with the clutch assembly, not the Volante FAW J6P em si. Isso é “lógica” is to ensure the clutch pressure plate is properly spaced and aligned when bolted to the flywheel, guaranteeing the correct clamp load and a clean release.
