FAW Auxiliary Fuel Tank, Bracket And Clamping Strap: A Comprehensive Guide to 13 Serviceable Components

Welcome to this comprehensive technical guide on the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 diesel semi-trailer tractor. This assembly is the complete auxiliary fuel storage and mounting solution, critical for long-haul routes.

The FAW Auxiliary Fuel Tank, Bracket And Clamping Strap system is a multi-part assembly designed to provide additional fuel capacity, extending the vehicle’s operational range. This system is engineered to be as robust as the main tank, involving the ‘Auxiliary fuel tank assembly’ (1102010-81R-C00), the heavy-duty ‘Bracket assembly’ (1101105-81R), and the secure ‘Clamping band assembly’ (1101135C50A).

This guide is an essential resource for professional technicians, chassis specialists, and parts managers. We will deconstruct the entire FAW Auxiliary Fuel Tank, Mounting Bracket, Clamping Band And Fuel Line system (referred to here by its 13 core mounting components) into its smallest serviceable units, ensuring every service or replacement is performed with factory-level precision.

Core Component: Auxiliary Fuel Tank Assembly (1102010-81R-C00)

The heart of the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap system is the ‘Auxiliary fuel tank assembly’ (1102010-81R-C00). This is the main reservoir, a high-capacity tank (often 200-400L) made of corrosion-resistant aluminum or steel, designed to work in tandem with the main fuel tank.

This assembly is more than just a container. The part number indicates it comes with a **fuel level sensor** pre-installed. This is a critical feature, as it provides the driver with an accurate reading for the auxiliary tank on the dashboard, allowing for effective fuel management and range calculation.

The tank is serviced via the ‘Fuel tank cover assembly’ (1103010-50A), which is the main filler cap. This cap must be properly sealed to prevent contamination, but also properly vented to prevent a vacuum from forming as fuel is drawn out. The ‘Intake/Exhaust pipe’ (1104301-50A) listed is likely this vent tube, which allows air to displace the fuel being used, preventing a vacuum lock that would starve the engine. The proper function of this entire tank assembly is central to the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap.

The “Bracket” System: A Rigid Chassis Mount

A full auxiliary fuel tank adds significant weight to the chassis. The “Bracket” components of the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap system are the heavy-duty structural supports that bear this load. The parts list calls for two ‘Bracket assembly-fuel tank’ (1101105-81R) units.

These are not simple “L” brackets; they are massive, C-channel or I-beam brackets forged or fabricated from heavy-gauge steel. They are designed to bolt directly to the truck’s main frame rail, creating a rigid “shelf” for the tank to sit on.

To prevent metal-on-metal contact, two ‘Gasket-bracket’ (1101117C50A) units are used. These are crucial strips of high-density rubber or polymer. They are placed on top of the steel brackets, creating a vibration-damping cushion. This prevents the truck’s road vibrations from fatiguing the aluminum tank and prevents “chaffing,” which could wear a hole in the tank over millions of miles.

The entire bracket sub-assembly is secured to the chassis frame rail with the four ‘Bolt-tighten fuel tank bracket’ (1101133-41A) fasteners. These high-tensile bolts are the foundation that holds the entire FAW Auxiliary Fuel Tank, Bracket And Clamping Strap system to the truck.

The “Clamping Strap” System: Securing the Tank

With the tank resting on its cushioned brackets, it must be firmly strapped down. This is the job of the “Clamping Strap” components of the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap system. The parts list calls for two ‘Clamping band assembly-fuel tank’ (1101135C50A) units.

These are long, flexible bands of high-tensile steel that are contoured to the shape of the tank. They wrap around the tank and connect to the brackets, creating a “cradle.” To protect the tank, two ‘Gasket-clamping band’ (1101134C50A) units are used. These are long rubber strips that line the *inside* of the steel bands, providing a non-slip, non-abrasive surface that grips the tank.

This design ensures the tank is held firmly in all directions (vertical, lateral, and longitudinal) while being completely isolated from direct metal-on-metal contact with the chassis. This anti-vibration “logic” is the most important feature of the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap mounting design.

Hardware: Pins, Bolts, and Nuts

The final components of the FAW Auxiliary Fuel Tank, Bracket And Clamping Strap are the serviceable hardware that completes the assembly. The ‘Flat head pin’ (Q5101485) and ‘Cotter Pin’ (Q5004030) are critical. The flat head pin likely acts as the “hinge” or “T-bolt” for the clamping band, allowing it to be anchored to one side of the bracket. The cotter pin is then used to secure this pin, or the tensioning nut, preventing it from ever backing off.

The four ‘Hex nut’ (CQ34012) and two ‘Gasket/Washer’ (Q40112, Q40114) units are used to apply the final tension. These nuts are threaded onto the ends of the ‘Bolt-tighten fuel tank bracket’ (1101133-41A) or the clamping band’s T-bolts, tightening the entire FAW Auxiliary Fuel Tank, Bracket And Clamping Strap down. These are not simple nuts; they are typically high-grade, prevailing-torque “lock nuts” to ensure they do not loosen under constant road vibration.
