Cat® Piston Wear Rings support and center the piston to prevent metal-to-metal contact between the piston and the cylinder wall.

Piston wear rings are not very costly, but fitting new ones can be. That is because to fit them a mechanic most often has to take the entire engine apart. For this reason replacing piston wear rings on Caterpillar equipment is often done as part of the Cat® Certified Rebuild Program.
