Product Details

Product Overview

This high-performance piston ring set is specifically engineered for the Cummins K19 and KTA19 diesel engine platforms. Designed as a direct replacement component, this kit includes essential rings for maintaining optimal compression, oil control, and overall engine efficiency. The set is identified by multiple cross-referenced part numbers including 4089500, 4081176, 3090450, and 3090460, ensuring compatibility with a wide range of heavy-duty applications.

Commonly used in excavators, trucks, forklifts, bulldozers, buses, and loaders, these piston rings are manufactured to OEM size specifications. They provide a reliable solution for engine rebuilds or repairs, helping to restore cylinder sealing and reduce blow-by in high-stress diesel power units.

Key Features & Benefits

• Direct Fitment: Manufactured to exact OEM size specifications for the K19 and KTA19 engine families, ensuring a precise seal without modification.
• High Durability: Constructed from premium-grade materials to withstand the extreme temperatures and pressures of turbocharged diesel combustion.
• Improved Compression: Restores lost compression power, enhancing engine performance, fuel efficiency, and cold-start reliability.
• Oil Control: Advanced ring profile design minimizes oil consumption by effectively scraping excess oil from the cylinder walls.
• Reduced Wear: Excellent surface finish and material hardness reduce friction against the cylinder liner, extending the life of both the rings and the engine block.
• Wide Application: Suitable for a variety of heavy equipment and industrial machinery powered by the K19 or KTA19 engine.

FAQ

Q: How do I confirm this piston ring set fits my specific engine?
A: The best way to confirm fitment is to locate the piston ring part number on your existing rings or in your engine’s service manual. If the number is 4089500, 4081176, 3090450, or 3090460, this set is the correct match for your Cummins K19 or KTA19 engine. If your number differs, please contact us with your engine serial number for verification.

Q: What is the recommended installation procedure for these rings?
A: Proper installation requires a piston ring expander tool to avoid twisting or breaking the rings. You must carefully check the ring end gap in the cylinder bore before installation to ensure it is within the factory service limits. Always stagger the ring gaps around the piston (typically 120 degrees apart for three-ring sets) to minimize blow-by. We recommend consulting the official Cummins service manual for your specific engine model.

Q: What does a worn piston ring set look like, and when should I replace these?
A: Common symptoms of worn piston rings include excessive oil consumption (blue smoke from exhaust), loss of engine power, high crankcase pressure, and difficulty starting. During an engine overhaul, rings should always be replaced along with the piston liners. Visually, worn rings may show a shiny or polished surface, reduced radial thickness, or broken ring lands.
