Коленчатый вал FAW J6P: 14 Важнейшие детали для безупречной мощности вращения

Welcome to this expert deconstruction of the Коленчатый вал FAW J6P, а “spine” of the engine for the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал.

This is not a single part but a complete “Логическая сборка” из 14 компоненты, all engineered to perform one task: to convert the violent, linear force of six pistons into the smooth, continuous rotational power that moves the truck.

The “логика” принадлежащий Коленчатый вал FAW J6P (P/N 1005014-36D) is all about force-transfer and balance, making it the most critical component for engine reliability.

The “Metallurgy Logic” принадлежащий Коленчатый вал FAW J6P is its most important feature. This is not a cast-iron component; it is drop-forged from a single billet of high-tensile steel. Этот “forged logic” is essential to withstand the two opposing forces that try to destroy it: а “сжатие” (the downward push of the combustion stroke) и “tension” (the high-RPM “stretch” as it pulls the piston back up). The entire assembly, 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, and fleet parts managers. We will deconstruct the entire 14-component group into its four primary “логика” система: а “Structural Core Logic” (the crankshaft itself), а “Front-End NVH & Логика привода” (the damper and pulley assembly), а “Rear-End Power Transfer Logic” (the flywheel assembly), и критический “Internal Sealing & Gearing Logic.” This is the complete guide to the Коленчатый вал FAW J6P.

Основной 1: The “Структурное ядро” Логика (Компонент 6)

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

1. Компонент: ‘Crankshaft’ (1005014-36Д / 1005014-36БД)
Этот (Комп 6) является основным Коленчатый вал FAW J6P. Его “Forged Logic” means it is forged from a single, high-tensile steel billet to handle the “сжатие” и “tension” forces. Его “Balancing Logic” is in the massive, integrated “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. Его “Fluid Logic” 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 Коленчатый вал FAW J6P.

Основной 2: The “Front-End NVH & Водить машину” Логика (Комп 1, 2, 3, 4, 8)

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

1. The “NVH Damping” Логика: ‘Silicone oil damper’ (1005190-36Д) & ‘Damper bolt’ (1005048К29Д)
Это “harmonic damper” (Комп 3). Его “логика” имеет решающее значение: every combustion stroke *twists* the Коленчатый вал FAW J6P slightly. Это “torsional vibration.” This damper, which is a heavy steel ring floating in a layer of silicone oil, является “настроенный” to that exact frequency. It oscillates *out of phase* with the crank, absorbing the twisting energy and turning it into heat. Этот “damping logic” prevents the Коленчатый вал FAW J6P from finding its resonant frequency and shattering. It is held on by six (6) ‘Damper bolts’ (Комп 1).

2. The “Аксессуар & Timing” Логика: (Комп 2, 4, 8)
The ‘Multi-groove belt pulley’ (Комп 2) bolts to the damper. Его “логика” is to transfer the crank’s rotation to the serpentine belt, which drives the alternator, водяной насос, и компрессор кондиционера. The ‘Crankshaft timing gear’ (Комп 8) is a toothed gear that drives the engine’s camshaft and/or injection pump, ensuring the valves and fuel are “timed” perfectly. The ‘Front oil seal’ (Комп 4) это “dynamic seal logic,” a high-temperature rubber lip seal that rides on the front of the crank, keeping the oil inside the crankcase.

Основной 3: The “Rear-End Power Transfer” Логика (Комп 10, 11, 12, 13)

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

1. Компонент: ‘Flywheel’ (1005121-630-0000)
Этот (Комп 12) это “Rotational Battery.” Его “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. Его “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’ (Комп 11) is likely part of this flywheel interface.

2. The “Застежка & Alignment” Логика: (Комп 10, 13)
The ‘Positioning key’ (Комп 10) is a small steel key. Его “логика” is to ensure the flywheel can only be installed onto the Коленчатый вал FAW J6P in *one* exact position. This is critical for timing and balance. The ‘Flywheel bolts’ (Комп 13) являются “Critical Fastener Logic.” The list calls for 10 high-tensile bolts. These are almost always “Torque-to-Yield” (телетайп) bolts that are *single-use* and must be replaced to prevent the flywheel from detaching under load.

Основной 4: The “Internal Sealing & Gearing” Логика (Комп 7, 9, 14)

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

1. Компонент: ‘Oil pump drive gear – коленчатый вал’ (1005039-36Д)
Этот (Комп 7) это “Lifeblood Logic.” This gear is pressed onto the Коленчатый вал 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 (в том числе Коленчатый вал FAW J6P сам) will be destroyed from oil starvation in minutes.

2. Компонент: ‘Rear oil seal’ (1005060-29Д)
Этот (Комп 9) это “Main Seal Logic.” It is a large-diameter, high-temperature rubber seal that is pressed into the engine block or a seal housing. Его “dynamic sealing” logic allows the Коленчатый вал FAW J6P to spin freely while preventing oil from leaking out of the “rear main” of the engine. A failure here results in a large, hard-to-fix oil leak between the engine and transmission.

3. Компонент: ‘Ball bearing 60305-2RS’ (ГБ/Т 276-1994)
Этот (Комп 14) это “Pilot Bearing Logic.” Этот маленький, sealed bearing is pressed into a recess in the *very end* of the Коленчатый вал FAW J6P. Его “логика” is to support the “nose” 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.
