Product Introduction: Spacer 6K4189 for Caterpillar Equipment
Overview
The Spacer 6K4189 is a precision-engineered component designed for Caterpillar equipment, specifically used to maintain precise alignment and spacing between components in linkage, hydraulic, or undercarriage systems, such as track or roller assemblies. This spacer ensures proper load distribution and operational stability in demanding applications, primarily track-type tractors and loaders. Available as a new aftermarket or genuine OEM part, it provides a reliable and cost-effective solution for equipment maintenance.
Key Features
- Material: Constructed from high-grade steel, designed to withstand high compressive forces, resist wear, and perform reliably in harsh operating conditions. Features a smooth, machined surface to ensure precise fitment and durability.
- Design: Precision-machined cylindrical or washer-shaped spacer, engineered to OEM specifications for accurate spacing and alignment. Optimized for high-stress environments, such as track roller or idler assemblies, to prevent component misalignment and reduce wear.
- Compatibility: Compatible with Caterpillar equipment, specifically:
- Track-Type Tractors: D6C, D6D, D6E, D6G, D7F, D7G, D8H, D8K.
- Track Loaders: 951B, 951C, 955H, 955K, 955L, 977H, 977K, 977L. Typically used in track assemblies (e.g., track rollers, idlers) or linkage systems to maintain proper spacing between components. Exact model compatibility must be verified using the equipment’s serial number via CAT SIS, as compatibility cannot be confirmed without it per Caterpillar’s policy.
- Dimensions: Specific dimensions are not publicly detailed but conform to OEM standards for the listed models, ensuring a precise fit. Typical spacers for track-type tractors are approximately 1-3 inches in diameter and 0.5-2 inches in thickness, based on similar components.
- Quality Assurance: Manufactured to meet or exceed US OEM specifications, with quality control conducted in ISO 9001-certified facilities.
Benefits
- Enhanced Durability: High-grade steel construction ensures exceptional strength and resistance to deformation, extending service life in rugged construction and earthmoving environments.
- Reliable Performance: Ensures precise component alignment, reducing wear and vibration in track or linkage systems, enhancing machine efficiency, and minimizing maintenance needs.
- Cost-Effective: Offers a high-quality aftermarket or OEM alternative, lowering maintenance costs compared to replacing entire assemblies. No core charge required.
- Ease of Installation: Engineered as a direct-fit replacement, streamlining the repair process and minimizing downtime.
Applications
The Spacer 6K4189 is designed for use in Caterpillar equipment, specifically suited for:
- Track-Type Tractors: D6C, D6D, D6E, for earthmoving and grading tasks, aligning with the user’s prior D6E focus (e.g., 504680 crankshaft, 8D8829 bushing).
- Track Loaders: 955L, 977L, for material handling and loading.
- Industries: Construction, mining, and forestry, where Caterpillar track-type equipment is employed for excavation, grading, and material movement.
