Bomba de óleo FAW J6P: 11 Peças críticas para uma lubrificação perfeita do motor

Welcome to this expert deconstruction of the Bomba de óleo FAW J6P (Conjunto principal P/N 1011010-36D). This component is the absolute “coração” of the engine for the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando.

While small, this “Logic Assembly” de 11 core component types is the single most critical component for engine survival.

O “lógica” do Bomba de óleo FAW J6P is to “collect” oil from the ‘Oil Sump’ e “pressurize” it, forcing it at 40-60 PSI through the engine’s tiny internal galleries. This high-pressure oil is the only thing separating all moving metal parts, like the crankshaft and bearings.

O “Positive Displacement Logic” is the key to the Bomba de óleo FAW J6P. É um “Gerotor” ou “gear-within-a-gear” bombear (Comp. 5). This design is critical because its output is directly proportional to engine RPM.

Esse “lógica” means it creates high *volume* at low-RPM (like at idle, to protect the turbo) and high *pressure* at high-RPM. No entanto, this also means it must have a “Safety Valve Logic” (Comp. 3, 4) to bleed off *excess* pressure at high speeds, which would otherwise blow out engine seals.

Uma falha no Bomba de óleo FAW J6P is not gradual; it is instant and catastrophic, leading to a complete engine seizure in minutes.

This technical guide is an essential resource for engine rebuilders, machine shop technicians, and fleet parts managers. We will deconstruct the entire 11-component-type group. Iremos analisar o “Positive Displacement Logic” (the pump gears and housing), o “Pressure Regulation Logic” (the safety valve), e o “Dirigir & Interface Logic” (the drive gears and fasteners) that define this Bomba de óleo FAW J6P.

Essencial 1: O “Positive Displacement” Lógica (Componente 5 & 7)

This group forms the core of the Bomba de óleo FAW J6P. É o “Gerotor” assembly that physically moves the oil.

1. Componente: ‘Oil pump assy’ (1011010-36D)
Esse (Comp. 5) é o principal “Pump Logic.” It is the complete assembly, containing the sub-parts that do the work. This assembly is the core of the auto_33 Bomba de óleo FAW J6P.

2. O “Gerotor” Lógica (Sub-Components):
Inside the main assembly, we find the key parts:

• ‘Oil pump drive gear shaft assy’ (1011020-36D) & ‘Drive gears’ (1011022-36D): Este é o “inner” engrenagem (Comp. 5). It is driven by the ‘Driven gear – bomba de óleo’ (Comp. 7). A lista pede dois (2) ‘Drive gears’, which form the “Gerotor” set.
• ‘Oil pump driven gear assy’ (1011030-36D): Este é o “outer” engrenagem (Comp. 5) that spins *around* the inner gear.
• ‘Oil pump cover plate’ (1011017-29D): Esse (Comp. 5) é o “Lógica de Selagem” that bolts to the pump body (Comp. 10), enclosing the gears and creating the high-pressure chamber.

O “Pumping Logic” é simples: as these two gears spin, o “crescent-shaped” gap between their lobes *increases* in size on the “sucção” lado, pulling oil in from the Cárter de óleo FAW J6P. As they continue to rotate, the gap *decreases*, squeezing the oil and forcing it out under high pressure. This is the positive displacement action of the Bomba de óleo FAW J6P.

Essencial 2: O “Drive Interface” Lógica (Componentes 7, 8, 10)

Este grupo “lógica” is to transfer power from the crankshaft to the Bomba de óleo FAW J6P‘s internal Gerotor set.

1. Componente: ‘Driven gear – bomba de óleo’ (1011014-36D)
Esse (Comp. 7) é o “Input Drive Logic.” This is the large gear that is visible on the *outside* of the Bomba de óleo FAW J6P habitação. Isso é “lógica” is to mesh directly with the ‘Oil pump drive gear’ (P/N 1005039-36D) that is located on the crankshaft. Esse “gear-on-gear” drive is a “no-slip,” non-stretch, life-of-the-engine solution, far more durable than a chain.

2. Componente: 'Casquilho – bomba de óleo’ (1011013-29D)
Esse (Comp. 10) é o “Sacrificial Bearing Logic.” The oil pump gears spin at high speed on steel shafts. Esse “bushing” is a soft, bronze-alloy sleeve that is pressed into the pump housing (part of Comp 5). The ‘Driven gear shaft’ (1011031-29D) spins inside this bush. Isso é “lógica” é ser o “wear item.” It saves the expensive aluminum pump housing and steel shaft from damage. This is a key serviceable part of the Bomba de óleo FAW J6P.

3. Componente: ‘Gasket – oil pump drive shaft’ (1011045-29D)
Esse (Comp. 8) é o “Thrust Logic.” It is a shim or gasket that sets the “jogo final”—the front-to-back movement—of the ‘Drive gear shaft’ (1011021A29D). This precise spacing is critical to prevent the gears from “binding” ou “walking” inside the housing of the Bomba de óleo FAW J6P.

Essencial 3: O “Pressure Regulation” Lógica (Componentes 1, 2, 3, 4)

This group is the “Safety Valve Logic.” A positive displacement Bomba de óleo FAW J6P would create infinite pressure (1000+ PSI) at high RPM, which would blow out every seal in the engine. This system prevents that.

1. Componentes: ‘Spring-oil pump safety valve’ (1011033-29D) & ‘Valve core…’ (1011032-29D)
Este é o “Relief Valve Logic.” The ‘Valve core’ (Comp. 4) is a small piston that blocks a “bypass” channel in the Bomba de óleo FAW J6P habitação. The ‘Spring’ (Comp. 3) is calibrated to hold this valve shut at normal pressures.

O “Spring Logic” is this: when oil pressure exceeds the spring’s rating (Por exemplo, 60-70 PSI), the pressure forces the ‘Valve core’ (Comp. 4) *back*, compressing the ‘Spring’ (Comp. 3). Esse “lógica” opens the bypass channel, allowing excess oil to bleed off, usually back to the “sucção” lado da bomba. This is how the Warning Bomba de óleo FAW J6P maintains a safe, stable pressure at all engine speeds.

2. Componentes: ‘Hexagon head plug’ (Q617B22) & ‘Copper gasket’ (Q/WC3403-1994)
Esse (Comp. 1 & 2) é o “Sealing Cap Logic.” This ‘plug’ and ‘gasket’ simply seal the “bore” that the safety valve and spring sit in. The ‘Copper gasket’ (Comp. 2) é a “arruela de pressão” that creates a perfect, de alta pressão, single-use seal.

Essencial 4: O “Fixador & Alignment” Lógica (Componentes 6, 9, 11)

Este grupo final “lógica” is to ensure the Bomba de óleo FAW J6P is mounted to the engine block with perfect alignment and vibration-proof clamping.

1. Componente: ‘Dowel pin’ (Q5220814)
Esse (Comp. 9) é o “Alignment Logic.” Bolts are *not* for alignment. This solid steel pin is pressed into the engine block, e o Bomba de óleo FAW J6P housing slides onto it *before* the bolts are inserted. Esse “lógica” guarantees perfect alignment, which is essential to ensure the ‘Driven gear’ (Comp. 7) meshes perfectly with the crankshaft’s drive gear.

2. Componentes: ‘Hexagon flange bolt’ (Q1840825) & ‘Hexagon flange nut’ (Q32010)
Este é o “Clamping Force Logic.” The four (4) ‘Bolts’ (Comp. 6) are the primary fasteners that hold the Bomba de óleo FAW J6P montagem no bloco do motor. The ‘Nut’ (Comp. 11) likely secures the main drive gear shaft. O “Flange Logic” of these fasteners means they have a built-in washer, which distributes the clamping load and resists vibration, preventing the Bomba de óleo FAW J6P from shaking loose.
