The genuine XCMG locating plate 800172383 is a precision-engineered alignment component designed for accurate positioning of drivetrain and hydraulic system assemblies in XCMG articulated dump trucks. This heavy-duty locating plate ensures exact component alignment, preventing misalignment that could lead to premature wear and system failure under extreme mining conditions. Manufactured from high-strength carbon steel with precision‑machined locating surfaces, the 800172383 locating plate provides reliable centering and mounting for transmission components, hydraulic valve blocks, and engine accessories. The locating plate is critical for maintaining the precise tolerances required in the ZF 8WG310 transmission and the OM460LA engine front housing.
Engineered to withstand vibration and torque reaction forces, the 800172383 locating plate features case‑hardened locating surfaces (48–55 HRC) and precision‑ground reference edges with a flatness tolerance of 0.05 mm across the entire plate. The locating plate incorporates dowel pin holes, threaded mounting bosses, and alignment slots that match XCMG’s original equipment specifications. Each plate is CNC‑machined from certified steel billet, deburred, and zinc‑nickel plated for corrosion protection in aggressive mining environments. Using genuine XCMG locating plates eliminates misalignment issues that cause premature bearing failure, gear noise, and hydraulic leakage.
The 800172383 locating plate is fully compatible with XCMG articulated dump trucks including the XDA30, XDA40, XDA45U, XDA60E, and XDA70 series. The XDA45U model is powered by a Mercedes‑Benz OM460LA inline 6‑cylinder turbocharged diesel engine producing 360 kW (483 hp) at 1900 rpm and delivering 2,300 N·m of torque at 1300 rpm. The locating plate is used in the transmission adapter housing and the hydraulic pump mounting bracket, ensuring that the torque converter, pump drive gears, and hydraulic manifolds remain perfectly aligned throughout the machine’s service life.
The following table provides complete technical specifications for the XCMG 800172383 locating plate, meeting all original equipment manufacturer standards for high-precision alignment in articulated dump truck assemblies.
The 800172383 locating plate is manufactured from high‑quality carbon steel billet, precision‑cut by CNC milling and grinding machines. The plate undergoes multi‑stage machining to achieve the exact geometry specified in XCMG’s original engineering drawings. The locating surfaces are case‑hardened to 48–55 HRC to resist wear from repeated assembly and disassembly, while the base material remains ductile to absorb shock loads. All reference edges and faces are ground to a surface finish of Ra ≤ 0.8 µm and flatness within 0.05 mm.
After machining, the locating plate is deburred and cleaned. The dowel pin holes are honed to H7 tolerance to ensure precise alignment with mating components. Each plate is 100% inspected on a coordinate measuring machine (CMM) to verify all critical dimensions—including hole positions, flatness, parallelism, and overall thickness. Random samples are subjected to hardness testing, case depth analysis, and magnetic particle inspection to detect any surface defects. The plates are then zinc‑nickel plated (≥500 h salt spray resistance) and oil‑dipped for corrosion protection.
The OEM locating plate 800172383 is used across the entire XCMG articulated dump truck range to ensure proper alignment of critical components. In the XDA45U, the plate locates the transmission adapter housing relative to the engine flywheel housing, guaranteeing concentricity between the crankshaft and the torque converter. This alignment is essential for preventing premature failure of the transmission pump bushing and the torque converter seal. The locating plate also serves as the mounting interface for the hydraulic pump drive assembly, maintaining precise gear mesh between the pump drive gear and the intermediate gear of the front gear train.
The permanent all‑wheel‑drive 6×6 system with 100% lockable differentials creates high torsional loads that can shift misaligned components. The 800172383 locating plate, with its hardened dowel pin holes and precision ground surfaces, prevents any movement between joined housings, preserving the original factory alignment throughout the machine’s service life. Field data from Australian iron ore mines and Indonesian coal operations confirms that genuine XCMG locating plates maintain dimensional stability and alignment accuracy for over 12,000 operating hours, while aftermarket plates often exhibit corrosion, edge deformation, or hole elongation after 6,000 hours.
Proper installation of the 800172383 locating plate is critical for achieving correct component alignment. Before installation, clean all mating surfaces on the engine block, transmission housing, and the plate itself using a lint‑free cloth and solvent. Inspect the locating plate for burrs, nicks, or corrosion. The dowel pin holes should be free of debris; use compressed air to blow them clean. Install the two locating dowels into the engine block or transmission housing, ensuring they are fully seated and not protruding beyond the required height.
Position the 800172383 locating plate over the dowels, ensuring it seats flush against the mounting face. Do not force the plate—if resistance is felt, check for misalignment or burrs. Install the four M10 mounting bolts with hardened washers, and tighten them in a cross pattern using a calibrated torque wrench to 45 Nm (33 lb·ft). For applications with additional preload, refer to the XCMG workshop manual for specific torque values. After the plate is installed, verify that the reference surfaces remain flat (no distortion) using a straight edge. Any distortion indicates that the mating face is uneven or the bolts were over‑torqued.
When reassembling the transmission or pump assembly, always replace the locating plate if it shows any signs of wear, corrosion, or distortion. Never reuse an old plate after a major overhaul, as the dowel pin holes may have elongated or the flatness may have been compromised. A follow‑up alignment check (e.g., dial indicator on the torque converter pilot) should be performed after the first 250 operating hours to confirm that the plate has maintained its position.
The 800172383 locating plate has been validated against XCMG’s durability standards for mounting and alignment components. Static load testing at 25 kN (over 5,600 lb) compressive force produced no permanent deformation or cracking. Fatigue testing (1 million cycles at 15 kN cyclic load) resulted in no measurable change in flatness or hole position. Corrosion resistance per ASTM B117 confirmed no red rust after 500 hours of salt spray exposure, ensuring the plate remains serviceable even in extreme coastal mining environments.
Field trials on XCMG XDA45U trucks operating in Australian iron ore mines and Indonesian coal mines involved 20 vehicles over 12,000 operating hours. Genuine 800172383 locating plates maintained flatness within 0.05 mm and dowel pin hole location within 0.05 mm of original specification. Aftermarket plates showed signs of edge corrosion, hole elongation, and flatness loss (exceeding 0.15 mm) by 6,000 hours, leading to transmission alignment issues, increased gear noise, and oil seal leaks.
Thermal cycle testing between -40 °C and +120 °C for 500 cycles produced no dimensional change or coating delamination. Hardness retention after 1,000 h at 120 °C showed less than 5% reduction, confirming the stability of the case‑hardened layer. Vibration testing (10–200 Hz, 1 million cycles) produced no loosening of the mounting bolts or movement of the locating plate relative to the housing.
Aftermarket locating plates pose serious risks to drivetrain alignment and component reliability. Non‑genuine plates are often made from lower‑grade steel with poor flatness and inaccurate hole positions, leading to misalignment of the transmission input shaft, pump drives, and hydraulic manifolds. Soft materials allow the dowel holes to elongate, and lack of corrosion protection leads to rust that contaminates the oil system. The consequences include premature torque converter failure, transmission pump seal leakage, gear whine and bearing wear, hydraulic system overheating from misaligned pump gears, and complete drivetrain disassembly for re‑alignment—costing tens of thousands of dollars in downtime and repairs.
Genuine XCMG 800172383 locating plates offer full material traceability from certified steel mills, documented heat treatment and machining records, 100% CMM inspection, flatness and parallelism certification, and a 12‑month warranty against manufacturing defects. Each plate is batch‑tested for compliance with XCMG’s OEM specifications for material grade, hardness, flatness, hole position tolerance, and corrosion resistance.
