The ATC W470589015900 Piston Ring Compressor is a heavy-duty precision tool designed for installing pistons in the block of the Detroit Diesel DD15 and Detroit Diesel DD16 engine families. As an OEM alternative to part numbers W470589015900 and J-47386, this ring compressor enables safe, consistent compression of piston rings for hassle-free insertion into the cylinder bore.
Designed specifically for the piston rings of the DD15/DD16 engines, the tool ensures rings remain properly aligned and protected during installation, reducing the risk of ring breakage, bore scoring, or piston damage. Many rebuild shops pair this compressor with the corresponding carbon scraper adapter (W470589021400) to maximize effectiveness.
