Product introduction
This Cummins intake valve repair kit, model number 2881836-10, is an original equipment manufacturer (OEM) repair kit specifically designed for K19/K38/K50 5.9L 24-valve engines. It includes high-precision machined intake valves, valve springs, valve catches, and other core components. The kit uses alloy steel valve stems (nitrided) and high-temperature alloy valve heads, making it suitable for high-intensity applications such as construction machinery and heavy-duty trucks. Laser-hardened working surfaces optimize sealing and reduce the risk of fuel leakage. As a valve repair kit, it strictly adheres to Cummins' original equipment manufacturer (OEM) standards, ensuring a proper match with engine guide clearances, extending engine life, and providing a reliable solution for maintaining 24-valve power systems.

Product Advantages
Featuring alloy steel valve stems (with nitrided surface) and high-temperature alloy valve heads, these valves can withstand temperatures exceeding 800℃, significantly improving wear resistance and ablation resistance. The valve working surfaces are laser-hardened, ensuring high precision matching with the valve seats, reducing the risk of gas leakage and optimizing engine combustion efficiency. The K19 Valve Repair Kit is specifically designed for Cummins K19/K38/K50 5.9L 24-valve engines, ensuring a proper fit with the valve guides, reducing oil consumption, and improving power output stability. Replacing the 5.9L 24V Cummins injectors requires specialized tools for removal and installation, as the injectors are secured by a clip inside the cylinder head and require very precise torque.
FAQ
Q: 1. What are the core components included in the Cummins 2881836-10 intake valve repair kit?
A: This kit includes high-precision machined intake valves, valve springs, valve catches, etc., made of alloy steel and high-temperature resistant alloys, compatible with K19/K38/K50 5.9L 24-valve engines.
Q: 2. How is the high-temperature resistance of this kit?
A: The valve head uses a special alloy coating, capable of withstanding temperatures above 800℃, suitable for high-boost conditions, and its sealing performance is optimized through laser hardening.
Q: 3.What is the HS code for this part?
A: Engine parts are generally classified under the 8409 series, but specific classifications depend on the material and function.
Q: 4. What are the packaging requirements for international shipping of precision engine parts?
A: External: Waterproof and dustproof wooden box;
Internal: Parts are fixed in sections and filled with foam or shock-absorbing materials;
Marking: Marked "Fragile," "Moisture-proof," and the product model (e.g., 2881836-10) and quantity.
Q: 5.What compliance requirements should be considered when exporting Cummins genuine parts?
