The 805604496 Pin is a precision-ground pivot pin engineered specifically for XCMG motor grader articulation and blade linkage systems. This heavy-duty pin serves as a critical rotational joint, allowing smooth movement while maintaining exact alignment between components. Manufactured from high-grade alloy steel, the 805604496 pin ensures reliable load transfer, reduced friction, and extended service life for your grader.
The 805604496 Pin is produced using a hot-forging process followed by precision CNC grinding to achieve exact dimensional tolerances. Each pin undergoes surface hardening to provide exceptional wear resistance while maintaining a ductile core to absorb shock loads. This combination makes the 805604496 ideal for the demanding articulation points on XCMG GR series motor graders, where cyclic loading and contamination are constant challenges.
Engineered for maximum durability, the 805604496 Pin features a zinc-phosphate coating with an oil film for corrosion protection. The pin’s chamfered ends facilitate easy installation, while the precision-ground bearing surfaces minimize play and prevent premature bushing wear. As a genuine XCMG replacement part, this pin meets all original equipment specifications for hardness, straightness, and surface finish.

Aftermarket pins often use lower-grade carbon steel with inconsistent heat treatment, leading to rapid wear or bending under load. The genuine 805604496 Pin from XCMG is manufactured from 42CrMo4 alloy steel, which offers an excellent combination of strength, toughness, and fatigue resistance. Finite element analysis confirms a 45% higher fatigue life compared to generic alternatives, meaning fewer breakdowns and lower operating costs.
Each 805604496 Pin is traceable to its raw material heat number and production batch. XCMG’s quality system includes 100% dimensional inspection using laser micrometers and air gauges. Magnetic particle inspection validates that there are no surface or subsurface cracks. This meticulous quality control ensures that every pin meets the demanding requirements of XCMG motor grader applications.
Installing the 805604496 Pin requires proper alignment of the linkage components. Begin by cleaning the pin bore and bushings thoroughly to remove any dirt or old grease. Apply a thin layer of molybdenum disulfide grease to the pin surface before insertion. Drive the pin using a brass drift to avoid damaging the hardened surface. Secure the pin with the original retaining clip or bolt.
Regular inspection of the 805604496 Pin is recommended every 250 operating hours. Check for axial movement, which indicates bushing wear. Measure pin diameter at three points using a micrometer; any reduction of more than 0.3mm requires replacement. Lubricate the pin through the grease fitting (if equipped) every 50 hours. A well-maintained pin can last over 8,000 hours in normal grading conditions.
Replacing worn pins with the genuine 805604496 Pin restores proper geometry to the blade linkage and articulation joints. Operators report smoother blade response, reduced play in the circle turn, and more accurate grade control. The precision-ground surface reduces friction, which minimizes hydraulic cylinder drift and improves fuel efficiency.
Field tests on XCMG GR215 graders showed that replacing all articulation pins with 805604496 reduced side play by 62% and eliminated clunking noises during direction changes. This improvement also protects bushings and bearing surfaces from uneven loading, extending their service life by up to 50%. For contractors who demand precision grading, genuine XCMG pins are a worthwhile investment.
XCMG’s pin manufacturing facility uses CNC lathes and centerless grinders to achieve consistent tolerances of ±0.01mm. The 805604496 Pin is induction hardened using a single-shot process that creates a uniform case depth of 1.5–2.0mm. This process eliminates soft spots that can lead to galling. Each production batch is tested for hardness profile and surface finish.
All 805604496 Pins are packaged in anti-corrosion paper within heavy-duty cartons. Bulk orders are available with individual barcode labeling for easy inventory management. XCMG’s global logistics network ensures fast delivery to any location, minimizing downtime for your grader fleet.
The 805604496 Pin directly replaces original part numbers 805604495 and 805604497. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders. It also fits certain wheel loader linkage applications, but always verify dimensions before ordering. The pin is used in blade lift arm pivots, circle turn joints, and articulation hitch points.
When rebuilding a linkage, replace the pin together with its mating bushings (XCMG part number 805604500) and seals (805604510). Using new components ensures correct clearances and maximum service life. XCMG recommends pin replacement every 5,000 hours or when diametral wear exceeds 0.4mm. Keep spare pins in your service truck to avoid unplanned downtime.
