مجموعة مبيت ناقل الحركة FAW: التركيز النقدي على 37 المكونات الأساسية

Welcome to this critical, in-depth guide on the مجموعة مبيت ناقل الحركة FAW, the complete structural “هيكل عظمي” for the gearbox in the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This is the foundation upon which the entire transmission is built.

ال مجموعة مبيت ناقل الحركة FAW ليس جزءا واحدا, but a set of precision-machined casings, including the ‘Front housing’ (1701015-A9P) and ‘Mid-housing’ (1701035-A9P). Its function is to contain the gear oil, protect all internal gears and shafts, and provide rigid mounting points to the engine and chassis.

This guide is an essential resource for professional transmission rebuilders, فنيو الأسطول, ومديري قطع الغيار. سنقوم بتفكيك الكل مجموعة مبيت ناقل الحركة FAW فيه 37 مكونات صالحة للخدمة, including every cover, سدادة, طوقا, and fastener required for a complete overhaul.

Core Casings: أمام (1701015-A9P) & Mid (1701035-A9P)

ال مجموعة مبيت ناقل الحركة FAW هو “two-piece” أو “split-case” تصميم, consisting of two main structural components.

**1. الإسكان الأمامي (1701015-A9P):** This is the ‘Front housing with steel wire sleeve assy’. هذا هو “السكن الجرس” قسم من مجموعة مبيت ناقل الحركة FAW. Its primary function is to connect the entire gearbox to the back of the engine’s flywheel housing. It also contains the clutch release mechanism (fork and bearing). ال “steel wire sleeve” (على سبيل المثال, هيليكويل) designation is a high-quality feature, indicating that the aluminum casting has been reinforced with steel thread inserts for the high-torque mounting bolts, preventing stripping and ensuring durability.

**2. Mid-Housing (1701035-A9P):** This is the ‘Mid-housing with steel wire sleeve assy’. هذا هو الشيء الرئيسي “علبة التروس,” the largest part of the مجموعة مبيت ناقل الحركة FAW. This heavily-ribbed casting (likely aluminum for light weight and heat dissipation) هو “هيكل عظمي” that holds all the critical, torque-bearing shafts: the main shaft, the counter-shaft, and the reverse idler shaft. الداخلية لها, precision-bored “saddles” are where the main shaft bearings are seated.

These two halves of the مجموعة مبيت ناقل الحركة FAW are located with ‘Dowel pins’ (1701052-A9P, 1701037-A2K) and bolted together with numerous high-tensile ‘Hex flange bolts’ (Q1840820S, Q1841030S, إلخ.) to form a single, جامد, leak-proof unit.

وصول & Inspection Covers

ال مجموعة مبيت ناقل الحركة FAW is designed for serviceability. This is evident from its multiple access covers. The ‘Cover – upper left’ (1701037-A9P) and ‘Cover – أسفل اليمين’ (1701043-A9P) نكون “العتاد الخامل” يغطي. They seal the large holes in the casing that are necessary for the factory to assemble the counter-shaft and idler gear clusters. These covers are sealed with gaskets and secured with ‘Hex flange bolts’ (Q1841060S, Q1841065S).

بالإضافة إلى ذلك, the ‘Front housing’ (السكن الجرس) features a ‘Cover – فتحة المراقبة الخارجية’ (1601042-A2K), which is sealed by a ‘Gasket’ (1601041-A2K). هذا صغير, removable plate is the “clutch inspection cover.” It allows a technician to use a light and a mirror to inspect the condition of the clutch friction disc, the pressure plate, and the release bearing, without having to remove the entire transmission. This is a critical diagnostic feature of the مجموعة مبيت ناقل الحركة FAW.

نظام التشحيم: Plugs and Sump

ال مجموعة مبيت ناقل الحركة FAW is also a “مستنقع” that holds several gallons of heavy-duty gear oil. This parts list details all the service points for this fluid.

**1. Filler Plugs:** The ‘Oil filler plug’ (1701042-A2K) هو الرئيسي “fill” ميناء, located high on the side of the مجموعة مبيت ناقل الحركة FAW. The transmission is filled until oil begins to weep from this hole, which is how the correct level is set.

**2. استنزاف المكونات:** The ‘Drain plug assy’ (1701765-A2K) is the service point for removing the old oil. This plug is located at the absolute lowest point of the مجموعة مبيت ناقل الحركة FAW. It is magnetic, designed to trap microscopic metal particles and provide a visual “health check” of the internal gears during an oil change. It is sealed with a ‘Gasket-plug, بالُوعَة’ (1701042-A2K… *Correction*: 1701042-A2K is listed as filler plug and gasket, likely a typo in list, should be drain plug gasket 1701765-A2K’s sub-part).

**3. Oil Sump:** The ‘Oil sump assembly’ (1701025-A9P) is a bolted-on component at the bottom of the مجموعة مبيت ناقل الحركة FAW. This acts as the main oil reservoir, ensuring the oil pump pickup is always submerged.

Shaft Support: Bearing Caps and Bushings

الوظيفة الأكثر أهمية لل مجموعة مبيت ناقل الحركة FAW is to hold the input, main, and counter shafts in perfect, parallel alignment under thousands of pound-feet of torque. This is achieved by several key components.

The ‘End cap – تحمل الجبهة رمح المتوسطة’ (1701028-A9P) is a heavy-duty cap that bolts to the front of the main housing, securing the “pocket bearing” of the counter-shaft. بصورة مماثلة, the ‘Cover – أول محمل خلفي رمح’ (1701141-A7G) و"الحشية".’ (1701142-A7G) seal and secure the main bearing on the transmission’s output shaft.

هذا مجموعة مبيت ناقل الحركة FAW also provides the mounting points for the shift-fork shafts. The ‘Bushing-shift fork shaft’ (1701013-A9P) and ‘Bushing-reverse idler shaft’ (1701014-A9P) هي “يرتدي” surfaces. These bronze bushings are pressed into the case, providing a low-friction, replaceable surface for the hardened steel shift shafts to slide in.
