FAQ

Q: How do I confirm this piston fits my Doosan DE12T engine?

A: First, locate your existing piston part number. If it matches 65.02501-0778, 65.02501-0778A, or 65.02501-0778C, this is the correct part. Also, verify your engine model is DE12, DE12T, DE12TIS, or D2366. You can also measure the piston diameter; this is a standard 123.00 mm size. If you have a modified or non-standard bore, please consult your engine manual.

Q: Does this kit come with the piston rings?

A: No, this specific listing is for the Piston Assembly which includes the piston body, wrist pin, and retaining clips. Piston rings are typically sold separately. Please ensure you order a compatible ring set for the 123.00 mm standard size to complete your engine rebuild.

Q: What is the recommended installation procedure for this piston?

A: Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is clean and within specifications. Lubricate the piston, pin, and cylinder walls with clean engine oil during assembly. Use a ring compressor to install the piston into the bore, taking care not to damage the ring lands. Always torque the connecting rod bolts to the manufacturer’s specified settings.
