FAQ

Q1: How do I verify this piston is correct for my engine?

Please confirm your engine model (e.g., 3TNV84, 4TNV84) and cross-reference your existing piston part number with our listed OEM numbers (129004-22080 or YM129004-22080). The piston is a direct replacement for these specific specifications.

Q2: What is the recommended installation procedure?

Professional installation by a qualified mechanic is recommended. Ensure the cylinder bore is clean and within service limits. Lubricate the piston and rings with engine oil during assembly. Use a piston ring compressor to install the assembly into the cylinder without damaging the rings.

Q3: Do I need to replace the piston rings and liners at the same time?

It is highly recommended to replace the piston rings and cylinder liners simultaneously to ensure a proper break-in and seal. This practice maximizes engine performance and extends the life of the new piston assembly.
