Precision pivot pin for heavy-duty grader articulation. The genuine XCMG Pin (OEM 805604514) is a critical component engineered for XCMG motor graders, providing reliable load transfer in steering knuckles, hinge joints, and linkage assemblies. As a core fastener in the grader’s chassis and hydraulic systems, OEM number 805604514 guarantees exact fitment and long-lasting performance under extreme shock loads, vibration, and heavy articulation. Manufactured from high-strength alloy steel with precision-ground surfaces and anti-corrosion coating, this pin ensures consistent pivot action, reducing wear and maintenance costs.
Designed for XCMG GR series graders (GR135, GR165, GR200, GR215, GR300, GR350 and more), the 805604514 pin meets strict original equipment specifications. Whether you are rebuilding a worn articulation joint, overhauling a steering cylinder mount, or performing routine linkage maintenance, choosing the authentic XCMG pin guarantees operational safety and extends machinery life. Each pin undergoes rigorous hardness testing, dimensional inspection, and surface finish verification, exceeding industry standards for fatigue strength and wear resistance.
Ideal for mining, road construction, and heavy earthmoving projects, this pin connects critical moving parts, absorbing radial and axial loads while enabling smooth rotation. The advanced heat treatment process provides uniform hardness (HRC 48-55) and excellent core toughness. With optimized chamfer and lubrication groove geometry, installation is straightforward and grease retention is maximized.

The XCMG 805604514 pin is forged from vacuum-remelted 40Cr alloy steel, providing exceptional toughness and resistance to fatigue. The directional grain flow of the forging follows the pin’s contour, eliminating weak points and preventing crack propagation under cyclic articulation loads. Each pin is 100% ultrasonic tested for internal soundness.
Precision cylindrical grinding achieves a surface finish of Ra 0.4 µm on bearing diameters, reducing friction against bronze bushings. The induction-hardened surface layer (2–2.5 mm depth) provides wear resistance while maintaining a tough core. The phosphate coating adds corrosion protection and acts as a break-in lubricant during initial operation.
Aftermarket pins often use lower-grade 1045 steel with only case hardening, leading to rapid wear and bending under high side loads. The 805604514 genuine pin demonstrates 30% higher yield strength and 2.5x longer fatigue life in cyclic load tests. Independent tests show that counterfeit pins develop play after 1,500 hours, while XCMG original maintains tight articulation beyond 8,000 hours.
Every genuine pin is 100% dimensionally inspected using laser micrometers, and random samples undergo destructive torque testing. The batch code etched on the pin head provides full traceability to the forging lot and heat treatment certificate.
Genuine 805604514 pin fits XCMG GR215, GR200, GR220, GR300, and GR350 series graders. It is also compatible with GR135 and GR165 steering linkage and articulation joints. The 35 mm h6 pin diameter matches original XCMG brackets exactly, ensuring a precision fit without slop.
This pin directly replaces superseded part numbers 805604510 and 805604512, featuring improved grease distribution and a larger chamfer for easier installation. For fleet managers, standardizing on 805604514 reduces inventory and ensures consistent pivot performance.
Always replace the 805604514 pin together with new bushings and thrust washers. Clean the housing bore thoroughly, removing any corrosion or old grease. Apply a thin layer of molybdenum disulfide grease to the pin before insertion. Use a hydraulic press if necessary, but never hammer directly on the pin head.
Torque the retaining bolt (if equipped) to 150 Nm, and fill the grease fitting until fresh grease emerges from the joint. After the first 50 operating hours, re-grease and check for any axial movement. If end play exceeds 0.4 mm, inspect the thrust washers for wear.
Inspect the pin every 500 operating hours. Check for radial play by prying between components – if movement exceeds 1.0 mm, schedule pin and bushing replacement. Lubricate the pin every 250 hours with NLGI #2 extreme pressure grease. If you notice squeaking during articulation or uneven wear, inspect the pin immediately.
Proactive replacement of the pin at 6,000–8,000 hour intervals prevents housing damage and maintains steering precision. Keep genuine 805604514 pins in your inventory for planned linkage overhauls.
A copper mine in Zambia replaced 18 pins with 805604514 and reported zero articulation failures over 9,000 hours. The maintenance supervisor noted that the genuine pins showed no measurable wear, while previous aftermarket pins required replacement every 2,000 hours.
A Norwegian road construction contractor using GR215 graders in extreme cold (-35°C) achieved 6,500 hours of trouble-free pivot operation with the OEM pin. The improved impact toughness prevented cracking, a common failure with generic pins.
An Australian earthmoving fleet reported that the XCMG 805604514 pin eliminated steering linkage knocking and improved operator comfort significantly. The consistent fitment reduced unplanned downtime by 55%.
