FAW Battery And Mounting Bracket Assembly: Deconstructing the 13 Critical Components for Reliable Power

Welcome to this critical technical guide on the FAW Battery And Mounting Bracket Assembly (حَشد 556). This is the complete, chassis-mounted electrical power supply and housing system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 diesel semi-trailer tractor. This assembly is the “heart” of the truck’s entire electrical system, providing the power for starting, lighting, and all onboard electronics.

ال FAW Battery And Mounting Bracket Assembly هو “logic” system designed for maximum durability and safety. Its function is twofold: first, it securely houses the two ‘Battery assembly’ (3703010-1086) وحدات, protecting them from extreme vibration, حطام الطريق, and weather. Second, its “logic” provides a robust, vibration-proof fastening system to ensure these heavy components never break loose.

This in-depth guide is an essential resource for professional technicians and fleet managers. We will deconstruct the entire FAW Battery And Mounting Bracket Assembly into its 13 serviceable components, including the main batteries, the ‘Battery press plate assy’ (3703160-92دبليو), the internal ‘Baffles’ and ‘Separators’, and the critical high-tensile fasteners that lock the system together.

Core Component 1: The ‘Battery Assembly’ (3703010-1086)

The core “قوة” component of this assembly is the ‘Battery assembly’ (3703010-1086). The parts list calls for two of these. This is the “logic” of a heavy-duty 24-volt electrical system. Passenger cars use a 12-volt system, but a high-compression diesel engine requires a much more powerful starter motor to turn over.

To achieve this, the FAW Battery And Mounting Bracket Assembly holds two 12-volt, high-cranking-amp (CCA) batteries. These batteries are then connected **in series** (the positive of one battery connects to the negative of the other). هذا “logic” doubles the voltage from 12V to 24V, providing the immense power needed for the starter motor. This 24V system also allows for the use of smaller-gauge (and thus lighter) wiring throughout the truck, which is a significant advantage in a large vehicle.

These are not standard car batteries; they are “heavy-duty” batteries, specifically engineered with reinforced internal plates and separators to withstand the constant, high-frequency vibration of a diesel engine and the severe jolts of a tractor’s suspension. A failure of one of these batteries will prevent the truck from starting.

Core Component 2: ال “Mounting Bracket” Logic

ال “Mounting Bracket” part of the FAW Battery And Mounting Bracket Assembly is a complete “system” of plates and baffles designed for total immobilization. A 30kg battery becoming a projectile in a collision or on a rough road is a catastrophic failure. This assembly’s “logic” is to prevent that at all costs.

يشمل هذا النظام:

• **’Battery press plate assy’ (3703160-92دبليو) & ‘Battery upper press plate’ (3703161-92دبليو):** This is the main “lid” أو “المشبك” that presses down on the *top* of the batteries. This provides the primary vertical securement.
• **’Battery baffle’ (3703162-92دبليو) & ‘Battery lower baffle’ (3703163-92دبليو):** These are the vertical and horizontal “walls” of the battery box.
• **’Battery separator’ (3703164-92دبليو):** This is a critical internal plate that sits *between* the two batteries. Its “logic” is to prevent the two batteries from rubbing or slamming into each other during cornering, which could crack their cases and cause a hazardous acid spill.

This entire cage-like structure is made from heavy-gauge, corrosion-resistant steel, as it must be able to withstand potential battery acid leaks. This robust “exoskeleton” is the core “logic” of the FAW Battery And Mounting Bracket Assembly.

Core Component 3: ال “Fail-Safe” Fastener System

ال FAW Battery And Mounting Bracket Assembly is held together by a redundant, “fail-safe” system of high-tensile fasteners. هذا “logic” is designed to be serviceable, yet immune to vibration.

**’Welded single-head stud’ (01100820) – 4 وحدات:** These are the foundation. These studs are permanently welded to the truck’s main chassis frame rail. The entire bracket assembly is “hung” from these four studs.

**’Battery fastening bolt’ (3703163-242 & -40أ) – 6 units total:** These are the “J-hooks” أو “tie-down” البراغي. Their “logic” is to hook into the bottom of the battery tray and pass up *through* the ‘Battery upper press plate’ (3703161-92دبليو).

**’Hex head flange lock nut’ (CQ32606) – 10 وحدات:** This is the most critical fastener “logic” of the assembly. These nuts are used to tighten the “J-hooks” down, clamping the batteries. ال “شفة” (integrated washer) provides a wide clamping surface. ال “lock nut” (prevailing-torque) design means the nut *cannot* vibrate loose. This ensures the batteries remain clamped, even after years of service.

**’Cross recessed pan head screw’ (Q2140614) – 10 وحدات:** These smaller screws, paired with ‘Gaskets’ (Q40108) and ‘Spring gaskets’ (س40308), are used to secure the ‘Battery press plate assy’ (the main cover) to the side baffles. ال “spring gasket” (lock washer) is another anti-vibration “logic” component, ensuring every part of the FAW Battery And Mounting Bracket Assembly is secure.
