Premium S6D114 6D114 6CT 6CT8.3 Piston Ring for Cummins Engine - Part Numbers 3802429 / 6D114-31-2020

Ensure peak performance and durability for your diesel engine with our high-quality piston ring sets.

Product Overview

The piston ring is a critical component in any internal combustion engine, and especially vital in heavy-duty diesel engines like those from Cummins. Our S6D114 6D114 6CT 6CT8.3 Piston Ring Set, featuring genuine or high-quality aftermarket compatibility with part numbers 3802429 and 6D114-31-2020, is engineered to provide a superior seal for optimal engine performance. These rings play a crucial role in sealing the combustion chamber, preventing blow-by of combustion gases, regulating engine oil consumption by scraping oil off the cylinder walls, and transferring heat from the piston to the cylinder wall.

Manufactured to strict quality standards, these piston rings offer excellent wear resistance, high tensile strength, and thermal stability, ensuring a long service life even under extreme operating conditions common in construction, mining, and heavy-duty trucking.

FAQs, Troubleshooting & Maintenance Tips

Q1: What are the common signs that my piston rings are worn or failing?

A1: Key indicators of worn piston rings include excessive blue or grey smoke from the exhaust (indicating oil burning), high engine oil consumption, loss of engine power or poor acceleration, and low compression readings during a cylinder compression test. You might also notice increased blow-by (combustion gases leaking past the piston into the crankcase).

Troubleshooting/Repair: A compression test is the most direct way to diagnose ring wear. If compression is low in one or more cylinders, piston ring replacement is likely required. This involves dismantling the engine to access the pistons.

Maintenance Tip: Regular engine oil and filter changes using the correct viscosity and quality oil specified by the engine manufacturer are crucial. Clean air intake systems prevent abrasive particles from entering the cylinders, which can accelerate ring wear. Avoid prolonged idling and consistent overloading of the engine.

Q2: How do I ensure I order the correct piston ring set for my specific Cummins engine?

A2: While part numbers 3802429 and 6D114-31-2020 are associated with the S6D114, 6D114, and 6CT/6CT8.3 series, engine variants and production years can sometimes have slight differences. The most reliable way is to verify the part number using your specific engine's serial number through the official Cummins parts catalog or by consulting a knowledgeable parts supplier like Guangzhou Pinxin.

Troubleshooting/Repair: Installing the wrong rings can lead to poor sealing, damage to the cylinder liner, or premature failure. Always confirm compatibility *before* installation.

Maintenance Tip: Keep a record of your engine's serial number and model information readily available. This makes ordering *any* replacement part much easier and more accurate.

Q3: What is the function of each ring in the piston ring set?

A3: A standard set typically includes three rings per piston:

Top Compression Ring: The primary seal against combustion chamber pressure, transferring heat from the piston crown to the cylinder wall.
Second Compression Ring: Provides a secondary seal and helps control any blow-by that gets past the top ring. It also starts the oil scraping process.
Oil Ring Assembly: This ring (often multi-piece) is designed specifically to scrape excess lubricating oil off the cylinder walls during the piston's downward stroke, allowing it to drain back into the oil pan and preventing it from entering the combustion chamber.

Troubleshooting/Repair: Damage to any one ring can compromise the function of the entire set, leading to performance issues. Always inspect all rings and the piston grooves during replacement.

Maintenance Tip: Ensure pistons and cylinder liners are thoroughly cleaned and inspected for wear or damage during engine overhaul. Proper ring gap and alignment are critical for correct function.
