Product Introduction: Cylinder Head 4509263 for Caterpillar C7.1 Diesel Engine
Overview
The Cylinder Head 4509263 is a precision-engineered component designed for the Caterpillar C7.1 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 heavy-duty applications, such as wheel loaders, excavators, motor graders, and generator sets. Available as a new aftermarket, remanufactured, or genuine OEM part, it provides a robust solution for engine maintenance.
Key Features
- Material: Constructed from high-grade cast iron, designed to withstand high temperatures, pressures, and mechanical stresses in the C7.1 engine. Features precision-machined surfaces for optimal sealing, heat dissipation, and durability.
- Design: Engineered to OEM specifications for precise fitment and performance. Includes valve seats, guides, and ports optimized for efficient combustion and exhaust flow. Typically delivered as a loaded assembly with pre-installed valves, springs, premium valve stem seals, retainers, injector cups, and cam bearings. Features advanced cooling passages to manage engine temperature effectively.
- Compatibility: Compatible with Caterpillar C7.1 diesel engines, used in:
- Wheel Loaders: 926M, 930M, 938M, 950 GC, 950M, 962M.
- Excavators: 320, 323, 326, 330, 336, 340.
- Motor Graders: 120, 140, 150, 160.
- Dozers: D5, D6K, D6K2.
- Generator Sets: C7.1 GEN SET, XQP200, XQP300.
- Other Equipment: Articulated trucks (725C, 730C), compactors (815, 816), track feller bunchers (522B, 541 Series 2), and industrial applications (e.g., mining, construction).
- Engines: C7.1 (7.1L, inline 6-cylinder, 24-valve configuration), with specific serial numbers (e.g., 6J6, 881, C7N). Exact compatibility must be verified using the engine’s serial number via CAT SIS, as per Caterpillar’s policy.
- Cross-References: 4509263, 3913193, 3737241, 4526584, 3845313, 3852572, T418502, 20R6647, 20R6648, 20R1033. The part number 4509263 is interchangeable with other C7.1 cylinder heads (e.g., 3913193, 4526584, 3845313) for specific serial numbers, indicating a shared design.
- Dimensions: Specific dimensions are not publicly detailed but conform to OEM standards for C7.1 engines. Typical loaded cylinder heads for C7.1 engines weigh approximately 250-300 lbs (113-136 kg), based on similar C7.1 cylinder heads (e.g., 3913193, 4526584).
- Quality Assurance: Manufactured or remanufactured in ISO 9001 or TS16949-certified facilities, meeting or exceeding Caterpillar OEM specifications. Subject to rigorous inspection, including pressure and vacuum testing, magnaflux testing, and surface grinding for flatness. Backed by a 12-month warranty for OEM parts (with labor coverage if installed by a Cat dealer), a 1-year unlimited mileage warranty for aftermarket parts, or a 6-month warranty for some remanufactured parts.
Benefits
- Enhanced Durability: High-grade cast iron construction ensures resistance to thermal stress, warping, and wear, extending service life in demanding construction, mining, and power generation environments.
- Reliable Performance: Optimizes combustion efficiency, airflow, and valve operation, maintaining the C7.1 engine’s power output (up to 300 hp for industrial, 450 hp for generator sets) and fuel economy, critical for heavy-duty applications.
- Cost-Effective: Offers high-quality aftermarket or remanufactured options, reducing maintenance costs compared to replacing entire engine assemblies. No core charge typically required for new parts, though remanufactured parts may involve a core deposit (e.g., $1,200 for similar C7.1 heads).
- Ease of Installation: Engineered as a direct-fit replacement, with loaded assemblies including pre-installed components to simplify installation, minimizing downtime. Professional installation by ASE-certified technicians is recommended due to precise torque requirements.
