FAQ

Q1: Is this piston compatible with my Doosan DE12 engine if the serial number is D2366?
A: Yes, this piston (65.02501-0773) is specifically designed for the Doosan DE12 engine variant identified as D2366. We recommend verifying your current piston’s part number to confirm a direct match. If your engine block has been bored oversize, please note that this is a standard-size piston.

Q2: Does this piston come with rings and a pin?
A: The part number 65.02501-0773 typically refers to the piston assembly. Please check the product listing to confirm if piston rings and a wrist pin are included. If not, we recommend purchasing a matched set (piston, rings, pin) to ensure proper clearance and performance.

A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Cleaning the cylinder bore thoroughly, 2) Lubricating the piston and rings with clean engine oil, 3) Using a proper ring compressor to avoid breaking the rings, 4) Torquing the connecting rod bolts to the manufacturer’s specifications. Always replace the connecting rod bolts as well. For specific torque values, refer to the Doosan DE12 engine service manual.
