FAQ

Q: How do I confirm this piston fits my Nissan SD23 engine?
A: Verify your engine model is SD23 and check the existing piston part number. This assembly directly replaces OEM numbers 12010-T6202 and 12010-09W01. If your part number matches either of these, the fitment is confirmed. For non-matching numbers, please contact our technical support with your engine serial number and original part details.

Q: What is included in the assembly – does it come with rings or circlips?
A: This product includes the piston and wrist pin (gudgeon pin) only. Piston rings and circlips are not included unless specified in the product listing. We recommend ordering piston rings separately (often available as a matched set) to ensure proper ring gap and tension. Circlips should be replaced with new ones during installation.

Q: What maintenance should I perform when installing a new piston?
A: Before installation, clean the cylinder bore thoroughly and measure it for wear or taper. Always replace piston rings and circlips with new components. Lubricate the piston skirt, pin, and cylinder bore with clean engine oil during assembly. Follow the engine manufacturer’s torque specifications for connecting rod bolts and ensure proper ring end gap orientation. After installation, perform a compression test to verify sealing.
