Bienvenido a esta guía técnica crítica sobre la Conjunto de carcasa delantera FAW. este es el completo “front cover” y “timing gear case” assembly for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This component is the structural face of the engine.
El Conjunto de carcasa delantera FAW es un complejo, precision-machined casting that performs multiple vital functions. It covers and seals the engine’s entire timing gear train, provides the mounting points for numerous critical accessories (like the fuel pump and power steering pump), and contains the passages for oil and coolant.
This in-depth guide is an essential resource for professional engine technicians and parts managers. Deconstruiremos todo Conjunto de carcasa delantera FAW en su 24 componentes reparables, including bearing covers, bomba de aceite, oil cooler piping, and the vast array of seals and fasteners required for a leak-free engine.
El corazón de la Conjunto de carcasa delantera FAW is the ‘Front housing with steel wire sleeve set assy’ (1701015-A2V). This is the main structural casting, typically made from high-grade aluminum to save weight. This is not just a “cover”; it is a load-bearing component that adds to the engine’s overall rigidity.
Its primary function is to create a sealed “caso” that encloses the engine’s entire timing gear train (as detailed in assembly 16). This case contains the high-velocity “splash” of oil that lubricates the timing gears, preventing it from leaking and protecting the gears from road dust and water.
El “steel wire sleeve set” (P.EJ., Helicoil) designation is a critical quality feature. It means the aluminum casting has been pre-fitted with hardened steel thread inserts. This is vital for all the accessory mounting bolts, as it prevents the soft aluminum threads from stripping during service, ensuring a secure, high-torque mount for the life of the Conjunto de carcasa delantera FAW.
El Conjunto de carcasa delantera FAW provides the mounting and sealing for several critical shafts that pass through it. The ‘Cover-first shaft rear bearing’ (1701141-A7G) and its ‘Gasket’ (1701142-A7G) are a key sub-assembly. Este es el principal “tapa” that bolts to the *inside* of the front housing, securing the large input shaft bearing (see assembly 143) in its bore.
Similarmente, the ‘End cap-intermediate shaft front bearing’ (1701028-A9P) es el “tapa” that seals and secures the front bearing of the transmission’s counter-shaft (see assembly 144). These bearing caps are not interchangeable and are precision-machined.
El Conjunto de carcasa delantera FAW also houses the ‘Bushing-shift fork shaft’ (1701013-A9P). This is a bronze bushing pressed into the housing, which supports the end of a shift rail from the “tapa superior” asamblea (see assembly 153). These bearing supports are what ensure all the transmission’s internal shafts are held in perfect, parallel alignment.
El Conjunto de carcasa delantera FAW is not just a case; it is an active part of the engine’s lubrication system. The ‘Oil pump assembly’ (1707840-A6V) is mounted *to* (or *in*) this housing, driven by a gear on the crankshaft. Esta asamblea es la “corazón” of the transmission’s own oil system, drawing fluid from the sump and force-feeding it to all the gears and bearings.
This system also includes the ‘Oil pipe assembly’ (1701435-A6V), ‘Oil spray pipe assembly’ (1701450-A2V), and ‘Intake oil pipe assembly’ (1701420-A2V). Estos son los “arteries” del Conjunto de carcasa delantera FAW. They are rigid pipes that route the pressurized oil from the pump to specific, critical locations, such as spraying a constant jet of oil onto the main gear-mesh points and into the bearings.
El Conjunto de carcasa delantera FAW also has service ports, such as the ‘Cover-outer observation hole’ (1601042-A2K) (the clutch inspection port) and its ‘Gasket’ (1601041-A2K), which are bolted to the front. These integrated oil-handling features make the Conjunto de carcasa delantera FAW a highly complex and critical component.
El Conjunto de carcasa delantera FAW must be perfectly sealed. This is accomplished by a large number of specialized fasteners and seals.
**sujetadores:** The entire assembly is secured with dozens of high-tensile ‘Hex flange bolts’ (Q1841030S, Q1840816, Q1841035S, Q1841050S, Q18410110S, Q1841230). The flange head and “S” tipo (o “t” tipo) designation indicate they are high-strength, vibration-resistant fasteners. ‘Hex head bolts’ (CQ1500616, CQ1501512S) and ‘Stud bolts’ (CQ1211640) are used in specific, high-load areas.
**Plugs & Seals:** The ‘Hollow dowel screw’ (1701442-A2V) and ‘Hollow bolt’ (1701440-A2V, 1701442-A2V) are “banjo” perno, used to connect the oil lines while allowing fluid to flow through them. They are sealed with ‘Gasket rings’ (1701415-A2V). The ‘Hydraulic pneumatic O-ring rubber seal’ (CQ7343236B) provides a critical seal for a high-pressure connection, likely for the oil pump or a sensor.
The ‘Hex nuts’ (CQ34008, CQ34116) y 'Juntas de resorte’ (Q40306, Q40405) are used to secure the stud bolts. This comprehensive hardware set is what ensures the Conjunto de carcasa delantera FAW can contain high-pressure oil and withstand constant engine vibration.
