Product Description – XCMG Pin Shaft 380907051
The XCMG Pin Shaft 380907051 have genuine OEM precision-machined cylindrical pin component designed for the XCMG GR215 series motor graders, including the GR2153, GR215A, and related heavy-duty grading models. This pin shaft serves as a critical pivot or hinge element within the grader’s front frame articulation, circle turn mechanism, blade lift linkage, or steering linkage – depending on the specific mounting location specified in the grader’s parts manual. Its primary function is to provide a durable, low-friction rotational joint between two structural components, allowing controlled angular movement under heavy cyclic loads while maintaining precise alignment and preventing unintended axial displacement.
Constructed from high-strength alloy steel, typically heat-treated to achieve a hardened surface (e.g., carburized or induction-hardened) with a tough core, the 380907051 pin shaft offers exceptional wear resistance, high shear strength, and resistance to bending under extreme static and dynamic loads encountered in road grading, land leveling, slope trimming, ditching, snow removal, and mining haul road maintenance. The shaft is ground to tight dimensional tolerances to ensure accurate fitment with corresponding bushings or bores in the mating components. A transverse cross-drilled hole may be present for a retaining bolt or grease fitting, depending on the design configuration. Common surface treatment includes anti-corrosion coating (e.g., zinc plating or black oxide) for protection against moisture, dust, and chemical deicers.
Direct interchange with the original factory pin shaft restores proper articulation clearance, eliminates excessive play or knocking in the linkage, reduces uneven wear to bushings and bearings, and prevents premature failure of surrounding structural components. Using an authentic XCMG pin shaft guarantees correct diameter, length, hardness profile, and retention feature geometry. Regular inspection of pivot pins is recommended for signs of wear, galling, or cracking, especially in high-hour graders working in abrasive or high-impact applications.
Applications: XCMG GR215, GR2153, GR215A, and other XCMG motor grader models that utilize the same pin shaft configuration in their frame, circle, lift arm, or steering systems. Always verify exact installation location against the grader's original parts diagram.
