1073565PK Piston Kit Fits Caterpillar Models

One New Aftermarket Replacement Piston Kit for Caterpillar (Cat) 3300 Series Engines

This aftermarket replacement piston kit is designed for Caterpillar (Cat) 3304 and 3306 series diesel engines, used across a wide range of Cat construction equipment including wheel loaders, dozers, scrapers, compactors, and skidders. The kit supplies the components needed to restore proper compression and engine performance during cylinder or overhaul service. Engine serial number ranges can affect kit configuration -- confirm your engine serial number before ordering.

Important: Always verify the part number stamped or etched on the crown of the piston -- not the casting number on the skirt -- before ordering or installing. The same casting blank (1073565) is machined into different finished pistons depending on valve relief configuration.
