N04CT Piston Ring Set for Hino Engine Parts Excavator Truck Diesel

Product Details

Product Overview

This N04CT Piston Ring Set is a direct-replacement engine component specifically designed for Hino N04CT diesel engines. As a critical element within the engine’s combustion system, this piston ring set ensures proper compression, oil control, and heat transfer, directly impacting engine performance and longevity.

Manufactured to OEM size specifications, this piston ring set is commonly used in a wide range of heavy-duty applications, including excavators, forklifts, trucks, loaders, bulldozers, and buses. It is an ideal solution for engine overhaul and repair projects requiring reliable sealing and minimal oil consumption. While designed for the Hino N04CT model, please verify your engine’s specific requirements before installation.

Key Features & Benefits

• OEM Size Precision: Manufactured to exact OEM dimensional standards, ensuring a perfect fit within the cylinder bore and groove without modification.
• Durable Material Construction: Made from high-grade cast iron or steel alloys to withstand extreme combustion pressures, high temperatures, and continuous friction.
• Enhanced Oil Control: The oil ring design effectively scrapes excess oil from the cylinder walls, reducing oil consumption and preventing carbon buildup.
• Improved Compression Seal: The compression rings create a tight seal between the piston and cylinder wall, maximizing power output and fuel efficiency.
• Extended Engine Life: By reducing friction and blow-by, this ring set helps maintain cylinder wall integrity and extends the overall service life of the engine.
• Rigorous Quality Control: Each set is inspected to ensure consistent thickness, tension, and surface finish for reliable performance.

Technical Specifications

OEM Cross-Reference

This piston ring set is designed as a direct replacement for standard Hino N04CT engine components. While specific OEM part numbers for the ring set may vary by engine revision, this set is intended to match the original factory specifications. Please cross-reference your existing part number with the details below:

• Engine Family: Hino N04C Series (N04CT)
• Applicable OEM Numbers: 13011-1780, 13011-1781, 13011-1790 (Reference numbers – verify with your existing ring set)
• Note: For exact fitment, compare the ring thickness, width, and diameter with your original parts. This set is for the standard bore size.

FAQ

Q1: How do I verify that this N04CT piston ring set fits my specific engine?

To confirm fitment, compare the ring set’s dimensions (diameter, thickness, and width) with your original piston rings. This set is designed for the standard bore size of the Hino N04CT engine. If your engine has been rebored or uses oversized rings, this standard set will not be compatible. Always consult your engine’s service manual or a qualified mechanic for verification.

Q2: What are the signs that my N04CT engine needs new piston rings?

Common symptoms include excessive oil consumption, blue smoke from the exhaust (indicating oil burning), reduced engine compression (leading to power loss), and increased blow-by (pressure escaping past the rings into the crankcase). If you observe these issues, replacing the piston rings during an engine overhaul is recommended to restore performance and efficiency.

Q3: Can I install this piston ring set myself, or should I hire a professional?

Installing piston rings requires specialized tools and mechanical expertise. The process involves removing the cylinder head, oil pan, and pistons, followed by careful ring gap measurement and installation. Incorrect installation can lead to engine damage. We strongly recommend having a certified diesel mechanic or engine rebuilder perform the installation to ensure proper fitment and ring alignment.
