5K0871
CAT
Primary Application
The 5K0871 is a Caterpillar Articulation Pivot Pin—also referred to as the "Lower Pin" or "PIN-LOWER."
Core Function:Supports the rotational movement of the articulation joint located between the machine's front and rear frames. This enables the motor grader to execute flexible steering and frame-articulation maneuvers, thereby enhancing maneuverability and precision during operation.
Installation Location: Installed at the articulation pivot point of a motor grader; it serves as a critical rotational pivot component within the steering system.
Product Category:Belongs to the Cat Machine Linkage Pins series, which supports any rotational connection point between machine frames, linkages, and work tools.
Common Equipment: Primarily utilized in motor graders, though it is also compatible with specific locations on certain wheel loader models.
Applicable Models (Common Examples):
- Motor Grader Series: 12G, 12H, 12H ES, 12H NA, 12K, 130G, 140G, 140H, 140K, 143H, 160H, 160K, 163H, etc.
- Others: Specific locations on wheel loaders such as the 950B, 950F, and 960F, as well as equipment powered by engines including the 3116, 3126, and C7 series.
As a wear-prone component in routine motor grader maintenance, this pin is susceptible to issues such as surface wear and increased clearance following prolonged operation under heavy loads. Regular inspection and replacement are essential to ensure smooth steering and structural stability, thereby preventing any compromise to grading precision or operational safety.
Product Features
Structural Type: Headed Pin—a steel pivot pin specifically engineered for high-strength rotational connections.
Installation Characteristics: Features "No Puller Hole"; the headed design facilitates easy installation and precise positioning. It is typically utilized in conjunction with corresponding bearings or bushings.
Performance Advantages:
- Manufactured from high-strength steel, enabling it to withstand the immense shear forces and impact loads generated during the motor grader's articulated steering maneuvers. - Supports precise rotational movement, ensuring smooth articulation between the front and rear frames, thereby enhancing overall operational stability and work efficiency.
