Product Parameters
| Parameter category | Detailed Description |
| Part number | 3801826-10 |
| Compatible engine series | Cummins K19, K38 and K50 series diesel engines |
| Material | High boron alloy cast iron (centrifugal casting process) |
| Surface treatment | Laser honing of the cylinder wall enhances wear resistance and oil film retention capacity |
| Compatibility | Original OEM specifications, fully matched with Cummins' original four sets (cylinder liner, piston, piston ring, connecting rod bushing) |
| Typical application | Major overhauls of high-power diesel engines for construction machinery, heavy trucks, Marine power, fixed generator sets, etc |
| High wear resistance | Adopting a customized high-boron alloy cast iron formula, the anti-wear performance is significantly enhanced, effectively resisting the high temperature and high pressure generated by diesel combustion as well as the erosion of particulate matter. |
| Compatible engine model |
K19 series : 19-liter displacement, commonly used in medium-sized construction machinery and generator sets K38 series : 38-liter displacement, widely used in mining machinery, ship propulsion and large tractors K50 series : 50-liter displacement, serves as the core power source for high-power heavy-duty equipment such as port cranes and railway locomotives |
Product Advantages
The K38 and K50 series utilize gallery-cooled pistons and a high-efficiency turbocharger system, coupled with a single-cycle cooling design, to effectively control cylinder liner thermal deformation under high-load conditions and improve combustion efficiency. The K19 and K38 models feature a plasma-treated molybdenum-infiltrated + tungsten disulfide composite coating on the cylinder liner surface, reducing the coefficient of friction by 30%, significantly minimizing power loss and improving fuel economy. The 3801826-10 kit, a dedicated kit for the NT855 engine, shares standardized maintenance procedures with the K19/K38/K50 models, supporting single-cylinder replacement without requiring complete disassembly, reducing maintenance costs and downtime.
FAQ
Q: 1. What are the core advantages of the Cummins K19, K38, and K50 cylinder liner repair kit?
A：Utilizing high-boron alloy cast iron centrifugal casting and laser honing processes, it achieves micron-level dimensional accuracy, is compatible with the original piston ring system, and significantly reduces oil consumption and the risk of cylinder scoring.
Q: 2. Is the 3801826-10 cylinder liner suitable for K19/K38/K50 engines?
A: The 3801826-10 is a kit specifically for the NT855 platform, sharing standardized interfaces and repair procedures with the K19/K38/K50 series, and can directly replace original worn parts.
Q: 3. Why choose original Cummins cylinder liners instead of aftermarket alternatives?
A:The original kit undergoes plasma molybdenum infiltration and tungsten disulfide composite coating treatment, reducing the coefficient of friction by 30% and exhibiting superior thermal stability compared to ordinary cast iron. Combined with the gallery-cooled piston design, it effectively suppresses thermal deformation under high-load conditions, preventing abnormal wear and cylinder liner cracks.
Q: 4. How long is the logistics time for shipping Cummins cylinder liner repair kits from Chongqing, China to Europe and America?
A:Exporting from Chongqing via the China-Europe Railway Express or air freight, the standard sea freight time is 35–45 days, and air freight is 7–10 days, including customs clearance and last-mile delivery. Tracking numbers and COC certification documents are provided throughout the process, and DDP terms are supported to ensure that end customers have no additional tax risks.
Q: 5.How to ensure that Cummins cylinder liners are not corroded or damaged during long-distance sea freight?
A:The kit is lined with an anti-rust oil film and sealed in a vacuum aluminum-plastic bag. The outer box uses EPE cushioning and moisture-proof cardboard. The entire kit has passed a 48-hour salt spray test without rust. Temperature and humidity are monitored throughout the transportation process to ensure that the performance is consistent with new parts upon arrival.
