FAQ

Q1: Is this kit suitable for a Caterpillar C15 engine with serial number prefix 2KS?

A: Yes, the 197-9322 liner and 346-6615 piston are standard for C15 engines with 2KS and 5EK prefixes. However, we recommend verifying your engine’s specific configuration (e.g., standard vs. oversized bore) by checking the cylinder block stamping, as some late-model ACERT engines may require a different piston profile.

Q2: Do I need to replace the connecting rod when installing this piston set?

A: No, the 346-6615 piston is designed to fit the standard C15 connecting rod (Part No. 7E-5172). You should, however, inspect the rod for wear and replace the wrist pin bushing if necessary. The kit includes a new wrist pin and snap rings, but the connecting rod itself is reused if in good condition.

Q3: What is the recommended installation procedure for the 310-4188 ring set?

A: Install the rings with the “TOP” marking facing upwards. Stagger the ring gaps 120° apart (do not align with the wrist pin). The top compression ring (chrome-faced) should be installed first, followed by the second compression ring (tapered face), and finally the oil ring (with expander). Lubricate with clean engine oil before inserting into the liner. Refer to the Caterpillar service manual (SENR1085) for torque specifications and final assembly steps.
