FAQ

Q1: How can I confirm this piston will fit my Cummins QSL9 engine?
A: First, check the part number stamped on your current piston. If it matches 5302254, 4987914, or C5298065, this is the correct part. Additionally, verify your engine’s serial number and displacement (it must be 8.9L with a 114mm bore). If you are unsure, please contact our support team with your engine model and serial number for verification.

Q2: What is included in the “Piston Kit”? Are rings and pin included?
A: This listing is for the piston assembly only. It includes the piston body with the steel insert. Piston rings and wrist pins are typically sold separately. We recommend ordering a complete overhaul kit (including rings, liners, and bearings) for a comprehensive rebuild. Please check the product variant or contact us for kit options.

Q3: What maintenance is required after installing a new piston?
A: After installation, it is critical to follow the engine manufacturer’s break-in procedure. This usually involves running the engine at varying loads for the first 50-100 hours without full throttle. Use high-quality diesel engine oil and replace the oil filter. Monitor for any abnormal noises or oil consumption. We recommend a full inspection at 250 hours to ensure proper seating.
