FAQ

1. Is this piston ring set a direct replacement for the Nissan 12040-96125 part number?

Yes, this set is manufactured to be a direct, drop-in replacement for the OEM Nissan part number 12040-96125. It matches the exact dimensions and material specifications for the PD6T engine.

2. What is the correct installation procedure for these rings?

Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is clean and within service limits. Install the rings using a proper ring expander tool to avoid breakage. Stagger the ring gaps 120 degrees apart and ensure the oil ring expander ends are not overlapped.

3. What is the recommended break-in period for new piston rings?

After installation, a proper break-in is crucial. Operate the engine under varying loads (avoiding constant high RPM or idle) for the first 1-2 hours. Use high-quality diesel engine oil with the correct API rating. This process helps the rings seat properly against the cylinder wall for optimal performance and longevity.
