Virabrequim FAW J6P: 14 Peças críticas para potência rotacional perfeita

Bem-vindo a esta desconstrução especializada do Virabrequim FAW J6P, o “coluna” of the engine for the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando.

This is not a single part but a complete “Montagem Lógica” de 14 componentes, todos projetados para executar uma tarefa: to convert the violent, linear force of six pistons into the smooth, continuous rotational power that moves the truck.

O “lógica” do Virabrequim FAW J6P (P/N 1005014-36D) is all about force-transfer and balance, making it the most critical component for engine reliability.

O “Metallurgy Logic” do Virabrequim FAW J6P é sua característica mais importante. This is not a cast-iron component; it is drop-forged from a single billet of high-tensile steel. Esse “forged logic” is essential to withstand the two opposing forces that try to destroy it: o “compression” (the downward push of the combustion stroke) e o “tensão” (the high-RPM “stretch” as it pulls the piston back up). Toda a assembleia, 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.

This technical guide is an essential resource for engine rebuilders, machine shop technicians, e gerentes de peças de frota. We will deconstruct the entire 14-component group into its four primary “lógica” sistemas: o “Structural Core Logic” (the crankshaft itself), o “Front-End NVH & Drive Logic” (the damper and pulley assembly), o “Rear-End Power Transfer Logic” (the flywheel assembly), e o crítico “Internal Sealing & Gearing Logic.” Este é o guia completo para o Virabrequim FAW J6P.

Essencial 1: O “Núcleo Estrutural” Lógica (Componente 6)

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

1. Componente: ‘Crankshaft’ (1005014-36D / 1005014-36BD)
Esse (Comp. 6) é o principal Virabrequim FAW J6P. Isso é “Forged Logic” means it is forged from a single, high-tensile steel billet to handle the “compression” e “tensão” forças. Isso é “Balancing Logic” is in the massive, integrado “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. Isso é “Lógica Fluida” 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 Virabrequim FAW J6P.

Essencial 2: O “Front-End NVH & Dirigir” Lógica (Comp. 1, 2, 3, 4, 8)

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

1. O “NVH Damping” Lógica: ‘Silicone oil damper’ (1005190-36D) & 'Parafuso amortecedor’ (1005048K29D)
Este é o “harmonic damper” (Comp. 3). Isso é “lógica” é crítico: every combustion stroke *twists* the Virabrequim FAW J6P slightly. Isso é “torsional vibration.” This damper, which is a heavy steel ring floating in a layer of silicone oil, é “sintonizado” to that exact frequency. It oscillates *out of phase* with the crank, absorbing the twisting energy and turning it into heat. Esse “lógica de amortecimento” prevents the Virabrequim FAW J6P from finding its resonant frequency and shattering. It is held on by six (6) ‘Damper bolts’ (Comp. 1).

2. O “Acessório & Timing” Lógica: (Comp. 2, 4, 8)
The ‘Multi-groove belt pulley’ (Comp. 2) bolts to the damper. Isso é “lógica” is to transfer the crank’s rotation to the serpentine belt, which drives the alternator, bomba de água, e compressor de ar condicionado. 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 “cronometrado” perfectly. The ‘Front oil seal’ (Comp. 4) é o “dynamic seal logic,” a high-temperature rubber lip seal that rides on the front of the crank, keeping the oil inside the crankcase.

Essencial 3: O “Rear-End Power Transfer” Lógica (Comp. 10, 11, 12, 13)

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

1. Componente: ‘Flywheel’ (1005121-630-0000)
Esse (Comp. 12) é o “Rotational Battery.” Isso é “Inertia Logic” 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. Isso é “Clutch Logic” is its large, perfectly flat, machined “friction surface.” The clutch disc presses against this surface, which is how 100% of the engine’s power is transferred to the transmission. The ‘Thrust ring’ (Comp. 11) is likely part of this flywheel interface.

2. O “Fixador & Alinhamento” Lógica: (Comp. 10, 13)
The ‘Positioning key’ (Comp. 10) is a small steel key. Isso é “lógica” is to ensure the flywheel can only be installed onto the Virabrequim FAW J6P in *one* exact position. This is critical for timing and balance. The ‘Flywheel bolts’ (Comp. 13) são os “Lógica de Fixador Crítico.” A lista pede 10 parafusos de alta resistência. These are almost always “Torque para rendimento” (TTY) bolts that are *single-use* and must be replaced to prevent the flywheel from detaching under load.

Essencial 4: O “Internal Sealing & Gearing” Lógica (Comp. 7, 9, 14)

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

1. Componente: ‘Oil pump drive gear – Virabrequim’ (1005039-36D)
Esse (Comp. 7) é o “Lifeblood Logic.” This gear is pressed onto the Virabrequim 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 (incluindo o Virabrequim FAW J6P em si) will be destroyed from oil starvation in minutes.

2. 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. Isso é “dynamic sealing” logic allows the Virabrequim FAW J6P to spin freely while preventing oil from leaking out of the “rear main” do motor. A failure here results in a large, hard-to-fix oil leak between the engine and transmission.

3. Componente: ‘Ball bearing 60305-2RS’ (GB/T. 276-1994)
Esse (Comp. 14) é o “Pilot Bearing Logic.” Este pequeno, sealed bearing is pressed into a recess in the *very end* of the Virabrequim FAW J6P. Isso é “lógica” is to support the “nariz” 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.
