FAQ

Q1: How do I confirm this piston fits my Doosan DM02 engine?
A: First, verify that your engine model is indeed DM02 (stamped on the engine data plate). Second, check the part number on your existing piston. If it reads 130602-01961A or 130602-01961, this assembly is a direct replacement. If you are unsure, please contact us with your engine serial number for assistance.

Q2: Does this piston come with piston rings?
A: This specific product includes the piston and the wrist pin only. Piston rings are sold separately. We recommend using a complete ring set matched to the DM02 engine to ensure proper ring end gap and groove fitment. Please check our store for the corresponding ring set.

Q3: What is the recommended installation procedure for this piston?
A: During installation, ensure the cylinder bore is clean and within service limits. Lubricate the piston skirt, pin, and cylinder wall with clean engine oil. Use a proper ring compressor to install the piston without damaging the rings. Torque the connecting rod bolts to the manufacturer’s specifications. We recommend consulting the Doosan service manual for your specific engine model for detailed torque values and procedures.
