FAQ
Q: Will this piston 8N3182 fit my Caterpillar 3306 engine? A: This piston is designed as a direct OEM replacement for the 8N3182 part number, which is commonly used in Caterpillar 3304 and 3306 diesel engines. To ensure a perfect fit, we strongly recommend comparing this part with your original piston and verifying your engine’s serial number against Caterpillar’s parts catalog.
Q: What is the installation process for this piston? A: Installation should be performed by a qualified diesel mechanic. Standard procedure includes cleaning the cylinder bore, lubricating the piston and rings, and using a ring compressor for installation. It is critical to check the piston-to-wall clearance and ring end gaps according to the engine service manual. We recommend replacing piston rings and liners simultaneously for optimal performance.
