PISTON - (.020) (CAT CT0379673)

A worn piston can reduce compression and cause excessive oil consumption. The piston is a cylindrical component that moves within a cylinder bore to transfer force from expanding gases to the connecting rod. A common failure consequence is blow-by, where combustion gases leak past the piston rings, reducing power output. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference number CT0379673. It is cataloged as a PISTON - (.020), indicating an oversize specification for cylinder reconditioning. The item ships at approximately 1.53 pounds.
