FAQ

Q1: Will this 247-6123 piston fit my Caterpillar C15 engine in a 374F excavator?
A: This piston is designed for the Caterpillar C15 (C-15) engine platform, which is commonly used in the 374F excavator. However, engine configurations can vary by serial number and production year. We recommend comparing the 137mm bore size and overall dimensions with your existing piston, or consulting your engine serial number to confirm compatibility.

Q2: What is the recommended installation procedure for this piston?
A: Professional installation is highly recommended. Ensure the cylinder bore is clean, within service limits, and properly honed. Lubricate the piston rings and skirt with clean engine oil during assembly. Always use new piston rings and a new cylinder liner if the liner is being replaced. Follow the Caterpillar C15 service manual for specific ring gap and torque specifications.

Q3: How should I store the piston if not installing immediately?
A: Store the piston in a clean, dry environment away from moisture and extreme temperatures. Keep it in its original packaging to protect the machined surfaces from scratches and contamination. Avoid exposure to corrosive chemicals or abrasive dust. Proper storage helps maintain the part’s integrity until installation.
