Precision-machined clamping plate for critical drivetrain retention. The genuine XCMG Clamping Plate (OEM 380901151) is a precision-engineered component designed for XCMG motor graders, providing reliable retention and load distribution in transmission assemblies, mounting brackets, and frame interfaces. As a critical fastening element in the grader’s drivetrain, OEM number 380901151 guarantees exact fitment and long-lasting performance under extreme torque loads, torsional stress, and heavy operating vibrations. Manufactured from high-strength ductile iron (QT600-3) with precision-ground mating surfaces and electrodes or phosphating corrosion protection, this clamping plate ensures consistent clamping force on gearbox and transfer case assemblies, reducing wear on driveline components and preventing misalignment-related failures.[reference:0][reference:1]
Designed for XCMG GR series graders (GR135, GR165, GR200, GR215, GR300, GR350 and more), the 380901151 clamping plate meets strict original equipment specifications. Whether you are rebuilding a worn drivetrain, overhauling a transmission, or replacing a cracked mounting component, choosing the authentic XCMG clamping plate guarantees operational safety and extends machinery life. Each plate undergoes rigorous dimensional inspection, flatness verification, and load testing, exceeding industry standards for strength and alignment accuracy.[reference:2]
Ideal for mining, road construction, and heavy earthmoving projects, this clamping plate anchors transmission components to the frame, maintaining proper driveline angles and preventing excessive flex that could damage gears or bearings. The advanced QT600-3 casting process provides uniform material density (tensile strength ≥600 MPa, elongation ≥3%), excellent vibration damping characteristics, and superior wear resistance.[reference:3][reference:4] With optimized bolt hole pattern and precision dowel pin locations, installation is straightforward and alignment is precise.
Each plate measures approximately 180 mm × 120 mm × 15 mm and is 100% inspected using CMM (Coordinate Measuring Machine) for flatness tolerances, with magnetic particle inspection to ensure zero micro-cracks or inclusions. The component is designed to withstand up to 8,000 hours of continuous operation in demanding conditions, providing peace of mind for fleet operators and maintenance teams alike.

The XCMG 380901151 clamping plate is produced using precision sand casting with controlled solidification, utilizing high-quality ductile iron grade QT600-3. This material is a pearlitic ductile iron developed for demanding mechanical applications, offering superior mechanical properties compared to conventional gray cast iron grades such as HT250 or HT300. Each plate achieves a minimum tensile strength of 600 MPa and an elongation of 3%, providing excellent resistance to shock loading and torsional stress while maintaining dimensional stability under heavy cyclic loads.[reference:11][reference:12] The spheroidal graphite structure in QT600-3 significantly reduces stress concentration effects, and its natural damping capacity reduces transmissible vibrations, protecting sensitive transmission components from resonance and fatigue-related failures.[reference:13][reference:14]
CNC-machined mating surfaces achieve a flatness of less than 0.05 mm, with surface roughness Ra ≤ 1.6 µm, guaranteeing a perfect fit against the transmission case and frame mounting brackets. The electrophoretic coating (E‑coat) provides superior corrosion resistance, tested to withstand 500+ hours of salt spray exposure per ASTM B117, ensuring long service life even in aggressive environments like mining, coastal construction, and snow removal operations.[reference:15]
Aftermarket clamping plates frequently suffer from lower strength due to use of gray iron instead of ductile iron, leading to warping, cracking, or bolt hole elongation under load. The 380901151 genuine clamping plate demonstrates at least 30% higher tensile strength and significantly better thermal cycling resistance compared to generic alternatives (gray iron typically 250 MPa tensile). Independent component tests show that counterfeit plates develop permanent deformation and misalignment after only 1,500 hours of heavy grader operation, while the XCMG original maintains precise drivetrain alignment beyond 10,000 hours, even in severe mining conditions.
Each genuine clamping plate is 100% inspected for dimensional accuracy using coordinate measuring machines (CMM), and random samples undergo tensile testing and hardness verification per ISO 6506‑1. The batch code laser‑engraved on the non‑mating surface provides full traceability to the foundry lot and heat treatment certificates.
Genuine 380901151 clamping plate fits XCMG GR215, GR200, GR220, GR300, and GR350 series graders, as well as GR135 and GR165 transmission applications. It is primarily used in transmission mounting systems, transfer case brackets, and drivetrain retention points requiring high clamping force and precise alignment. The bolt hole pattern and dowel pin locations match original XCMG specifications exactly, eliminating the need for shimming or modification during installation.
This clamping plate directly replaces superseded part numbers 380901148 and 380901149, featuring an improved QT600-3 metallurgy for higher load capacity and superior fatigue resistance. For fleet managers, standardizing on 380901151 reduces inventory complexity and ensures consistent drivetrain mounting performance across the grader fleet.
Always replace the 380901151 clamping plate together with new mounting bolts (grade 10.9) and dowel pins if the originals show signs of wear. Clean the mating surfaces on both the transmission and frame brackets thoroughly, removing any old gasket material, oil residue, or corrosion that may affect seating. Install the plate using dowel pins to ensure exact alignment before tightening fasteners. Tighten the retaining bolts in a cross pattern to the specified torque (typically 55 Nm for M12 bolts), then re‑torque after 50 operating hours to account for initial embedment.
Inspect the plate for cracks or deformation prior to installation. Do not overtighten bolts beyond the specified maximum, as this may distort the plate and affect driveline alignment. Use a calibrated torque wrench for all final tightening procedures.
Inspect the clamping plate every 1,000 operating hours for signs of cracking, surface corrosion, or loose mounting bolts. Use a dial gauge to measure runout at the transmission output shaft – increase beyond 0.15 mm may indicate a warped or misaligned clamping plate. Check for visible corrosion on the coated surfaces – if rust breakthrough appears, the coating has been compromised, and replacement is recommended.
Proactive replacement of the clamping plate at 8,000–10,000 hour intervals (depending on application severity) prevents catastrophic transmission misalignment and gear damage. Keep genuine 380901151 plates in your inventory for planned drivetrain overhauls.
A Chilean copper mine replaced 38 clamping plates across their GR215 fleet with 380901151 and reported zero drivetrain alignment issues over 14,000 operating hours. The maintenance supervisor noted that the genuine QT600-3 plates showed no signs of warping or cracking, while previous aftermarket castings failed after 3,000 hours due to fatigue cracks propagating from bolt hole edges.
An Australian mining fleet using GR300 graders in haul road maintenance achieved 9,000 hours of trouble‑free transmission performance with the OEM clamping plate. The high flatness accuracy eliminated the need for shimming, reducing installation time by 40% compared to aftermarket alternatives.
A Canadian mining contractor reported that the XCMG 380901151 clamping plate withstood extreme cold (-40°C) and heavy impact loads without any loss of alignment, outperforming generic plates that cracked within a single winter season due to brittle fracture of gray iron materials.
