PISTON (CAT CT20718)

A worn piston can cause reduced compression and increased oil consumption in the cylinder. The piston is a cylindrical component that moves within the cylinder bore to transfer force from expanding gases to the connecting rod. Catalog reference CT20718 is an aftermarket replacement part, cross-referenced to the OE maker CAT. A common failure consequence is blow-by, where combustion gases leak past the piston rings into the crankcase. During operation, the piston must withstand high temperatures and repeated pressure cycles. Verify the serial number or application, then call (562) 693-7748. This part is listed as a piston for general replacement use.
