Product Introduction: Cylinder Head 3068171 for Cummins K50 Engine
Overview
The Cylinder Head 3068171 is a precision-engineered component designed for the Cummins K50 diesel engine, critical for sealing the combustion chamber, housing the valves, and facilitating efficient airflow and fuel combustion. This part is essential for maintaining engine performance and reliability in demanding applications, such as industrial, marine, and power generation equipment. Available as a new or remanufactured original Cummins part or aftermarket equivalent, it provides a robust solution for engine maintenance.
Key Features
- Material: Constructed from high-grade cast iron or steel alloy, designed to withstand high temperatures, pressures, and mechanical stresses in the K50 engine. Features precision-machined surfaces for optimal sealing and heat dissipation.
- Design: Engineered to OEM specifications for precise fitment and performance. Includes valve seats, guides, and ports optimized for the K50’s high-performance requirements, supporting efficient combustion and exhaust flow. May include pre-installed valves and springs in some assemblies.
- Compatibility: Compatible with Cummins K50 engine models, including:
- Engine Variants: KTA50, QSK50, used in industrial applications (e.g., mining, construction), marine propulsion, and generator sets (e.g., KTA50-G3, KTA50-G8). Specific applications include articulated trucks, large excavators, and power generation units. Exact compatibility must be verified using the engine’s serial number, as per Cummins’ policy.
- Dimensions: Specific dimensions are not publicly detailed but conform to OEM standards for K50 engines, ensuring a precise fit. Typical cylinder heads for large Cummins engines like K50 are substantial, weighing 200-300 lbs (90-136 kg) due to their size and robust construction.
- Quality Assurance: Manufactured or remanufactured in facilities adhering to ISO 9001 standards, meeting or exceeding Cummins OEM specifications.
Benefits
- Enhanced Durability: High-grade materials ensure resistance to thermal stress, corrosion, and wear, extending service life in high-load industrial and marine environments.
- Reliable Performance: Optimizes combustion efficiency, airflow, and valve operation, maintaining the K50 engine’s power output (up to 1875 hp) and fuel economy, critical for heavy-duty applications.
- Cost-Effective: Offers a high-quality aftermarket or remanufactured alternative, reducing maintenance costs compared to replacing entire engine assemblies. No core charge typically required for new parts.
- Ease of Installation: Engineered as a direct-fit replacement, minimizing downtime during engine overhauls or repairs, though professional installation is recommended due to the component’s complexity.
Applications
The Cylinder Head 3068171 is designed for use in Cummins K50 engines, specifically suited for:
- Industrial Equipment: Large articulated trucks (e.g., Caterpillar D400E), mining excavators, and drilling rigs.
- Marine Applications: Propulsion systems for commercial vessels, requiring high torque and reliability.
- Power Generation: Generator sets (e.g., KTA50-G3, KTA50-G8) for standby or prime power in data centers, hospitals, and industrial facilities.
- Industries: Mining, construction, oil and gas, marine, and power generation, where Cummins K50 engines are deployed for high-performance tasks.
Technical Specifications
- Part Number: 3068171 (cross-referenced as 306-8171, 3649935 for some KTA50/QSK50 applications).
- Unit of Measure: Each.
- Condition: New, remanufactured, or aftermarket.
- Weight: Approximately 200-300 lbs (90-136 kg), estimated based on similar Cummins K50 cylinder heads (e.g., 3649935).
