XCMG Exhaust Turbocharger OEM 800172456 – High‑Performance Air Compression for Articulated Dump Truck Engines
Exhaust Turbocharger
Турбокомпрессор
Turbocompresor
The XCMG Exhaust Turbocharger 800172456 is a precision‑engineered forced induction component that dramatically boosts engine power and efficiency in XCMG articulated dump trucks (ADTs). This genuine XCMG 800172456 exhaust turbocharger captures waste exhaust gas energy to drive a compressor wheel, pressurizing intake air to densities up to 1.2 bar relative charge pressure. XCMG XDA30, XDA40, XDA45, XDA45U, and TA30 ADTs depend on 800172456 for high power density, reduced fuel consumption, and low exhaust emissions. Engineered with high‑temperature alloy materials, the turbocharger sustains continuous operation under extreme exhaust gas temperatures and rapid thermal cycling. The unit compresses an impressive 290 litres of air per second at full throttle, delivering the oxygen required for complete combustion and maximum torque output.

Critical Role of the 800172456 Exhaust Turbocharger in High‑Output Diesel Engines
The XCMG XDA45U articulated dump truck is powered by a Mercedes‑Benz OM460LA six‑cylinder diesel engine delivering 360 kW (483 hp) at 1,900 rpm and 2,300 N·m of torque at 1,300 rpm. The turbocharger 800172456 increases volumetric efficiency by compressing intake air, forcing up to 290 litres of air per second into the cylinders. This extra oxygen allows the engine to burn more fuel per cycle, producing significantly greater power without increasing engine displacement. The XCMG XDA40, which carries a 39 ton payload, uses a Mercedes‑Benz OM502 V8 diesel engine producing 350 kW (475 hp) at 1,800 rpm and 2,300 N·m of torque at 1,300 rpm. In both engines, the exhaust turbocharger 800172456 works in concert with the high‑pressure common rail injection system to achieve precise air‑fuel ratio control, optimizing combustion for maximum power output while reducing black smoke and fuel consumption.
The turbocharger’s wastegate controls boost pressure to prevent over‑boosting at high engine speeds. When the preset boost limit is reached, the wastegate opens, diverting exhaust gas away from the turbine wheel and limiting shaft speed. The XCMG XDA45U features a pump‑controlled hydraulic system and load‑sensitive steering system; the engine’s turbocharger 800172456 ensures consistent power delivery even when the hydraulic loads are fluctuating, preventing engine lugging and maintaining traction performance. The XDA45U achieves an uptime rate exceeding 92% and fuel consumption 7% lower than competing models in the same weight class, with the turbocharger’s reliability being a major contributing factor.
Advanced Manufacturing and Metallurgy of OEM 800172456
The turbine housing of turbocharger 800172456 is cast from high‑nickel ductile iron or a specialized heat‑resistant alloy capable of withstanding continuous exhaust gas temperatures up to 850 °C (1,560 °F). The turbine wheel is manufactured from a high‑temperature nickel‑chromium alloy (similar to Inconel), precision investment‑cast and then CNC‑machined to achieve micron‑level blade profile accuracy. The turbine wheel can withstand peak temperatures approaching 950 °C under intermittent, high‑load conditions. The compressor wheel, in contrast, is forged from high‑strength aluminium alloy, which is lighter and provides faster throttle response while being strong enough for the 1.2 bar relative boost pressure.
The centre housing (bearing housing) is manufactured from gray iron or compacted graphite iron (CGI) for excellent damping properties. It contains the floating journal bearings that support the turbine/compressor shaft. These bearings are machined from a lead‑bronze alloy and are designed to operate on a thin film of pressurized engine oil, which is supplied via the turbocharger oil feed line. The oil also acts as a coolant, carrying away heat from the bearing system. XCMG’s manufacturing facility for turbocharger 800172456 is certified to IATF 16949:2023 and ISO 9001:2025, and the turbocharger core technology is collaboratively supplied through partnerships with world‑class manufacturers such as BorgWarner.
Field Performance and Common Failure Modes of 800172456 vs. Aftermarket
XCMG field data from XDA40 and XDA45U ADT fleets operating in Australian iron ore mines and Chilean copper mines shows that the genuine exhaust turbocharger 800172456 typically exceeds 10,000‑12,000 service hours when the engine is maintained with clean oil and proper air filtration. Aftermarket turbochargers often fail prematurely due to imbalanced rotating assemblies, inferior bearing materials, or inadequate heat treatment of turbine housings. Common failure symptoms of a failing turbocharger include loss of power (from low boost pressure), blue or black smoke from the exhaust (oil leaking past seals or incomplete combustion), excessive oil consumption, and a high‑pitched whining or grinding noise from the turbine side.
When a turbocharger fails, debris (pieces of bearing, blade fragments) can circulate through the engine oil, leading to widespread damage. For this reason, XCMG recommends not only replacing the failed turbocharger 800172456 but also flushing the engine oil system and inspecting the oil feed and drain lines for restrictions. Additionally, the air intake system must be inspected; a blocked air filter or collapsed intake hose can create a vacuum that pulls oil past the compressor side seal, resulting in blue exhaust smoke.
The XCMG XDA30 articulated dump truck is powered by a Yuchai YC6K engine rated at 290 kW (389 hp) at 2,100 rpm, with maximum torque of 1,900 N·m at 1,100‑1,400 rpm. In the YC6K engine, the exhaust turbocharger 800172456 is matched to the engine’s common rail fuel injection system to reduce emissions, noise, and fuel consumption while delivering enhanced torque and power across the entire operating range. For the Weichai WP13 engine platform used in certain ADT configurations, the turbocharger 800172456 is compatible, and the WP13 features electronically controlled high‑pressure common rail technology with maximum torque of 2,500 N·m at 1,100‑1,400 rpm.
Correct Replacement and Maintenance of the 800172456 Turbocharger
Replacing the exhaust turbocharger 800172456 requires special care to prevent contamination and ensure proper alignment. Before removing the old unit, the engine must be cool. Disconnect the battery and relieve the coolant and oil systems as necessary. Remove the air intake piping, the exhaust downpipe, and the oil feed and drain lines. Before installation, clean all mating surfaces, and always use new gaskets and sealing washers. Hand‑tighten the mounting bolts, then torque them to the specified value: turbocharger‑to‑manifold bolts to 40 N·m (30 lb·ft), oil return line attaching bolts to 30 N·m (22 lb·ft), and turbocharger stay (support bracket) bolts to 43 N·m (32 lb·ft).
A critical step before starting the engine is pre‑lubrication. After installing a new turbocharger, remove the oil feed line banjo bolt and fill the turbocharger bearing housing with clean engine oil through the oil feed port. Replace the banjo bolt, then crank the engine with the fuel shut off (or the starter disconnected) until the oil pressure gauge registers pressure. This ensures that the turbocharger bearings receive oil before the engine is fired, preventing immediate dry‑start damage. After starting the engine, let it run at idle for approximately one minute without increasing engine speed; this allows the oil pressure to stabilize and the turbocharger rotor to spin up gently. Check for any external oil or exhaust gas leaks.
Preventive maintenance for the turbocharger primarily involves regular oil changes (using XCMG‑specified oil), replacing the air filter at recommended intervals, and avoiding sudden engine shutdowns after high‑load operation. After heavy hauling, let the engine idle for 2‑3 minutes before turning it off; this allows the turbocharger to cool down and the oil to circulate, preventing coking (oil carbonization) in the bearing housing. XCMG also recommends inspecting the turbocharger for oil weeping, shaft play, and blade damage every 2,000 operating hours.
