Product Details
Product Overview
This high-quality piston ring set, identified by part number 13011-4040A and OEM reference 30926, is a direct replacement component designed for the Hino J08E diesel engine. Commonly utilized in heavy-duty applications such as excavators and trucks, this 112mm diameter piston ring assembly is critical for maintaining optimal compression, reducing oil consumption, and ensuring efficient engine performance.
Manufactured to genuine OEM specifications (Rik brand as referenced in the original identification), this piston ring set is suitable for engines produced between 1989 and 2004. It is an essential component for engine rebuilds or repairs on Hino vehicles and equipment powered by the J08E model. Please verify your engine’s specific requirements and ring configuration before installation to ensure compatibility.
Key Features & Benefits
Precision Fit for J08E: Engineered specifically for the Hino J08E engine platform, ensuring correct ring gap, tension, and profile for reliable sealing.
Genuine OEM Quality: Manufactured to the original equipment specifications of the 30926 and 13011-4040A part numbers, providing long-lasting durability.
Optimized Compression: Restores cylinder compression, improving engine power, fuel efficiency, and reducing blow-by in heavy-duty excavator and truck applications.
Oil Control: Designed to minimize oil consumption by providing an effective seal between the piston and cylinder wall, reducing emissions and operating costs.
Durable Construction: Made from high-grade materials suitable for the thermal and mechanical stresses of diesel engine operation, offering a service life of up to 3 months under standard operating conditions.
Complete Set: Includes all necessary rings for a single piston, simplifying the purchasing process for engine rebuild kits or individual cylinder repairs.

FAQ
Q: How can I confirm this piston ring set (13011-4040A) fits my specific Hino J08E engine? A: First, verify your engine’s cylinder bore diameter is exactly 112mm. Second, cross-reference your old ring set’s part number (often stamped on the rings or box) with 13011-4040A or 30926. Finally, check the ring profile—this set is designed for standard J08E applications. If your engine has been rebored or uses oversized rings, this standard set will not fit. We recommend comparing the ring thickness and profile against your original parts.
Q: What is the recommended installation procedure for these piston rings? A: Proper installation is critical. Clean the ring grooves thoroughly. Install rings starting from the bottom (oil ring), then second compression ring, and finally the top compression ring. Use a piston ring expander to avoid twisting or breaking the rings. Ensure ring gaps are staggered at 120 degrees around the piston (avoid aligning gaps with the wrist pin or thrust face). Always lubricate the rings and cylinder bore with clean engine oil during assembly. For detailed steps, consult a Hino J08E service manual.
Q: What does the 3-month warranty cover, and what is excluded? A: The 3-month warranty covers manufacturing defects, such as material flaws or incorrect dimensions that prevent proper installation. It does not cover damage caused by improper installation (e.g., broken rings from over-expansion), incorrect fitment verification, or normal wear and tear from use. If you suspect a defect, contact us for video technical support to diagnose the issue before returning the product.
