FAQ

Q1: How do I confirm that this piston kit fits my Cummins 6C 8.3L engine?
A: Verify your engine’s model number (e.g., 6C, 6CT, 6CTA) and the existing piston diameter. This kit is 114mm STD, suitable for engines requiring standard-size pistons. Cross-reference your part number with 3917707, 3802263, or 3802459. If unsure, check the engine serial number or consult your equipment’s service manual.

Q2: What is included in this piston kit, and what additional parts do I need for a complete overhaul?
A: This kit includes the piston body, piston pin, and retaining clips. For a complete top-end overhaul, you will also need piston rings, cylinder liners, connecting rod bearings, and gaskets. We recommend replacing all wearable components in the cylinder assembly simultaneously to ensure optimal engine performance.

Q3: Can I use this piston kit in a Komatsu PC300-7 excavator with a non-Cummins engine?
A: This piston kit is specifically designed for Cummins 6C 8.3L engines. The Komatsu PC300-7 commonly uses a Cummins 6CT8.3 engine. If your machine has a different engine brand or model, this kit will not be compatible. Always match the engine manufacturer and model, not just the machine model, before purchasing.
