FAQ

Q: How do I confirm this piston is the correct part for my specific Caterpillar C18 engine?
A: While this piston is designed for the C18 platform, we strongly recommend cross-referencing the part number (3687815 or 368-7815) with your engine’s specific serial number (ESN) or the part number from your original failed component. Engine sub-models or production years may have variations.

Q: Is this piston sold as a single unit or as a set?
A: This piston is sold as a single item. For a complete engine overhaul, a full set (matching the number of cylinders in your engine) must be purchased to ensure balanced performance. Please order the required quantity accordingly.
