Caterpillar 2V-7366 Piston

The Caterpillar 2V-7366 piston is an original Cat component designed for use inside Cat linear actuating cylinder assemblies, where it serves as the moving element that converts hydraulic pressure into precise linear motion. In Caterpillar catalogs, the part is cross-listed as 3040-01-444-9317, confirming its identity as a hydraulic cylinder piston rather than an engine piston and aligning it with Cat’s OEM cylinder hardware.
