Overview:
This Piston Ring for Kubota tracked dumpers is a Genuine Kubota engine component, supplied under OEM No. 12657 21050. It is designed for the AV2500 and KC50 models, where it seals the combustion chamber, controls the oil film on the cylinder wall, and transfers heat from the piston to the liner.
