FAQ

Q1: Is this piston assembly a direct fit for all Caterpillar C15 engines?
A: This assembly (346-6615) is a standard fitment for many C15 engine models. However, due to variations in engine serial numbers and configurations (e.g., ACERT vs. Pre-ACERT), we strongly recommend you verify the part number against your existing piston or consult your engine’s parts manual to ensure compatibility.

Q2: Does the assembly include all necessary hardware for installation?
A: Yes, this product includes the piston, wrist pin, and retaining clips. You will typically need new piston rings and cylinder liners for a complete overhaul. We recommend replacing the connecting rod bolts and main bearings as well to ensure a reliable rebuild.

Q3: What is the expected lifespan of this aftermarket piston compared to a genuine Caterpillar part?
A: Our aftermarket pistons are manufactured to meet or exceed OEM specifications using high-quality materials. Under normal operating conditions and with proper maintenance, they can provide a service life comparable to genuine parts. The actual lifespan depends on factors such as engine load, fuel quality, and maintenance intervals.
