FAQ

Q: How do I confirm this piston fits my Nissan RH8 engine?
A: Verify the part number stamped on your existing piston. It should match either 12011-63787 or 12011-63760. Additionally, measure the chamber diameter; it must be 74mm. If your engine block has been previously rebored, you may require an oversized piston, so always check the current cylinder bore size.

Q: Does this piston come with piston rings?
A: No, this product includes only the piston and the piston pin. Piston rings are sold separately. We recommend using new rings from a reputable manufacturer to ensure proper sealing and oil control during your engine rebuild.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: cleaning the cylinder bore thoroughly, lubricating the piston and rings with clean engine oil, using a piston ring compressor to install the assembly, and torquing the connecting rod bolts to the manufacturer’s specifications. Always consult the Nissan RH8 engine service manual for exact torque values and procedures.
