FAQ

Q1: Is the piston pin included with this part?
A: Yes, the part number 65.02501-0590 includes both the piston and the fully-floating piston pin. Retaining clips are also included for installation.

Q2: Can I use this piston in a turbocharged DE12T engine?
A: Absolutely. This piston is designed for both the naturally aspirated DE12 and the turbocharged DE12T. It is built to withstand the higher thermal and mechanical loads of a turbocharged application.

Q3: What is the recommended installation procedure?
A: We recommend replacing pistons in sets (all 6). During installation, ensure the cylinder bores are honed to the correct finish. Always lubricate the piston pin and rings with clean engine oil prior to assembly. Follow the manufacturer’s torque specifications for the connecting rod bolts.
