Welcome to this expert technical guide on the FAW Oil Sump (Partie no. 1010010-51B), a component of paramount importance for the lubrication system of the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel. This is the engine’s primary oil intake.
This component, le FAW Oil Sump, is also known as the oil pickup tube. C'est le “straw” that the high-volume oil pump uses to draw the entire supply of engine oil from the oil pan. Its correct position, mounting, and sealing are non-negotiable for engine health.
This guide is an essential resource for professional engine technicians, gestionnaires de flotte, et spécialistes des pièces détachées. Nous déconstruirons l'ensemble FAW Oil Sump assemblée, including its main body, its critical gasket, its complex support brackets, and all associated high-tensile fasteners, down to the smallest serviceable unit.
The core component of this system is the ‘Oil Sump Assembly’ (1010010-51B). This is the complete pickup tube unit. The design of the FAW Oil Sump est critique. It consists of a large-diameter, pre-bent pipe that is precision-engineered to position its “head” at the absolute lowest point of the oil pan’s sump.
Le “head” de la FAW Oil Sump is a wide, bell-mouthed inlet. This inlet is covered by a durable, coarse wire mesh screen. This screen is the engine’s first and most important line of defense against oil-borne debris. Any large foreign objects in the pan (such as gasket fragments, carbon chunks, or metal shavings from wear) are blocked by this screen, preventing them from being sucked into the high-pressure oil pump.
A failure of this screen, or a clog from excessive engine sludge, will starve the engine of oil. The main pipe of the FAW Oil Sump connects this pickup head to the oil pump’s intake port, usually located on the engine block’s “bed plate” or on the pump body itself. Toute la fonction du FAW Oil Sump is to provide an uninterrupted, faire le ménage, and non-aerated supply of oil to this pump.
The ‘Gasket-Oil Sump’ (1010012-53D) is the single seal that connects the flange of the FAW Oil Sump (1010010-51B) to the oil pump’s intake port. The importance of this one gasket cannot be overstated.
This gasket is not sealing oil *out*; it is sealing *air* out. The oil pump’s intake is a high-suction (vacuum) area. If this gasket is cracked, improperly installed, or re-used, it will allow the oil pump to suck in air from the crankcase along with the oil. This aerates the oil, turning it into a compressible foam.
Foamy, aerated oil is un-pumpable. It cannot maintain the critical hydrodynamic film in the engine’s bearings. A failure of this one, small gasket will lead to a rapid and catastrophic loss of oil pressure, even if the oil pan is full. This results in the destruction of the crankshaft bearings, turbocompresseur, and camshaft journals. Donc, this gasket must be replaced any time the FAW Oil Sump is unbolted.
Le FAW Oil Sump pickup tube is a relatively long, rigid pipe. If it were only supported by its main flange, the constant, high-frequency vibration of the diesel engine would quickly cause it to fatigue-crack, typically at the weld near the flange. This would cause it to fall into the oil pan, leading to immediate oil starvation.
To prevent this, a robust support system is essential. This parts list details two key support components for the FAW Oil Sump: the ‘Fixed Bracket Assembly’ (1010020-81D) and the ‘Oil Sump Bracket’ (1010017-51B).
The ‘Fixed Bracket Assembly’ (1010020-81D) is the main brace. It is a heavy-duty stamped steel bracket designed to bolt to a secure point on the engine block’s structure, such as one of the main bearing cap bolts. The other end of this bracket then bolts to the pickup tube, providing a solid, immovable anchor point deep inside the engine.
The ‘Oil Sump Bracket’ (1010017-51B) serves as a secondary support, likely triangulating the tube from another angle. This dual-bracket system locks the FAW Oil Sump in place, holding it perfectly rigid and preventing it from being damaged by vibration or shock. These brackets are a critical part of the FAW Oil Sump‘s reliability.
A vibration-proof assembly is only as good as its fasteners. The list for the FAW Oil Sump includes a specific set of hardware. The two ‘Combination Bolt’ (CQ1460840) units are the primary bolts. UN “boulon combiné” a un pré-installé, rondelle captive (usually a spring-lock washer and a flat washer). These are used to secure the main flange of the FAW Oil Sump to the oil pump, with the ‘Gasket-Oil Sump’ (1010012-53D) sandwiched between. The spring washer prevents the bolt from backing out under vibration.
The support brackets are secured with a set of ‘Hex Flange Bolts’ (Q1841020, Q1840820). The flange-head design integrates the washer, spreading the clamping load and resisting loosening. The list calls for two (Q1841020) and two (Q1840820) boulons. This varied set of fasteners is used to bolt the brackets to the engine block and to the FAW Oil Sump tube itself.
Enfin, the single ‘Hex Flange Nut’ (Q039608) indicates that one of the support brackets mounts to a pre-installed stud on the engine block, a common design for high-vibration areas. This nut completes the locking system, ensuring the entire FAW Oil Sump assembly remains rigid for the life of the engine.
Le tableau suivant fournit l'intégralité, detailed breakdown of all components identified in the ‘Oil Sump’ schéma du tracteur FAW CA4251P66K24T1A3E5. Any service of the FAW Oil Sump requires careful inspection of these parts, especially the gasket and support brackets.
