Complete Shacman Tail Tube Assembly DZ97259546798 for X5000 Truck Exhaust System

The Tail Tube Assembly DZ97259546798 is a complete, fully assembled OEM exhaust component designed and manufactured by Shacman for the X5000 Truck. This genuine part, identified by the precise OEM number DZ97259546798, constitutes the final section of the vehicle’s exhaust system, responsible for safely directing treated engine gases away from the truck’s rear. It is more than just a simple pipe; it is an integrated assembly that includes the tail pipe, mounting brackets, and sometimes a short section of connecting pipe or flanges, ready for direct bolt-on installation. The correct function of this assembly, specifically part DZ97259546798, is crucial for ensuring proper exhaust flow, minimizing backpressure, and maintaining safe operation by preventing fumes from entering the cabin or collecting around the vehicle.

Constructed from durable, high-temperature resistant aluminized or stainless steel, this assembly is engineered to withstand corrosive exhaust gases, road salt, and extreme thermal cycling. A compromised or leaking tail tube can lead to increased cabin noise, toxic fume hazards, reduced engine efficiency, and failure to pass emissions inspections. By choosing the genuine Shacman Tail Tube Assembly DZ97259546798, you ensure a perfect fit, optimal exhaust scavenging, and long-term durability that matches the original equipment performance of your Shacman X5000 Truck.

The Tail Tube Assembly DZ97259546798 serves several critical functions. Primarily, it acts as the final discharge point for exhaust gases that have passed through the diesel particulate filter (DPF) and selective catalytic reduction (SCR) system. Its design ensures gases are expelled at a safe distance from the truck’s body and rear components, preventing heat damage and fume ingress. The assembly also maintains the correct exhaust backpressure.

Proper backpressure is essential for the optimal operation of turbochargers and emission control systems. A correctly sized and fitted tail tube ensures the exhaust system “breathes” efficiently. Furthermore, the integrated brackets provide secure mounting, preventing excessive movement that could lead to metal fatigue, cracks at welds, or damage to upstream exhaust components like flexible couplings.

The Shacman DZ97259546798 assembly is built for longevity. Aluminized steel offers a excellent balance of cost and corrosion resistance, where an aluminum-silicon coating forms a protective layer against rust. In more demanding applications, stainless steel variants may be used for maximum durability. The pipes are mandrel-bent to maintain a consistent internal diameter.

Mandrel bending prevents kinking and wrinkling, which can restrict flow and create turbulence. Welds are performed using MIG or TIG processes for strong, clean joints. The included mounting brackets are made from thicker-gauge steel than the pipe itself and are often welded at reinforced points to handle the vibrational stress. This robust construction ensures the assembly outlasts universal fit parts.

Replacing the tail tube assembly is a straightforward job best performed on a lift. Safety first: allow the exhaust system to cool completely. Support the existing assembly, then remove the fasteners at the connecting joint (flange or clamp) and the bracket mounting bolts. Carefully lower the old assembly. Compare the new DZ97259546798 unit with the old one to confirm identical configuration.

Clean the mating surface on the upstream pipe. If a gasket is included, install it. Position the new assembly, loosely fasten all brackets and the main connection. Align the tube for proper clearance from the chassis, fuel lines, and bodywork, then sequentially tighten all fasteners to the specified torque. Never force the assembly into position, as this indicates misalignment.

A damaged or corroded tail tube assembly poses multiple risks. Leaks before the rear of the vehicle can allow toxic exhaust, containing carbon monoxide, to enter the cabin or draft into the HVAC system. Severe rust can lead to complete separation, creating a road hazard. Restricted flow from dents or internal collapse increases backpressure, reducing engine power and fuel efficiency, and potentially causing overheating of upstream components. Always address a failing tail tube promptly by replacing it with the genuine DZ97259546798 assembly.

Does this assembly include the muffler or DPF/SCR canister?

No. The Tail Tube Assembly DZ97259546798 typically refers to the pipe section from the outlet of the final muffler or after-treatment device to the very end of the vehicle. It does not include the muffler, diesel particulate filter (DPF), or SCR catalyst. It is the final discharge pipe.

How often should the tail tube be inspected?

Inspect visually during every oil change or routine service. Look for signs of severe surface rust (especially at joints and brackets), holes, cracks in the welds, dents that restrict flow, and loose or broken mounting hardware. Pay extra attention if you operate in regions that use road salt.

Can a small hole in the tail pipe be welded shut?

While possible as a temporary field repair, welding thin, corroded exhaust metal is often unsuccessful long-term. The surrounding metal is usually weak, and the patch may not hold. For a reliable, permanent fix and to prevent further corrosion spread, replacing the entire assembly (DZ97259546798) is the recommended solution.

The Tail Tube Assembly DZ97259546798 is an essential, fully-integrated component that completes the exhaust system of your Shacman X5000 Truck. Its role in ensuring safe gas expulsion, maintaining engine performance, and providing durable service is critical. Choosing the genuine Shacman assembly guarantees a perfect fit, superior materials, and compliance with the vehicle’s original design specifications.

Don’t compromise your truck’s safety, performance, or compliance with makeshift repairs. For a reliable, long-lasting solution, insist on the exact OEM part number DZ97259546798 for your exhaust system maintenance and upgrades.
