FAQ

Q1: How can I confirm this piston will fit my Yanmar 3TNC80 engine?

Verify your engine model number (3TNC80, 3D80-1, or 3TNC80L) stamped on the engine block data plate. Cross-reference your existing piston’s OEM part number with the numbers listed (119812-22080, 121450-22011, 121450-22010). Measure your current piston pin diameter – this unit features a 23mm pin. If all match, this piston is the correct replacement.

Q2: What installation precautions should I take when replacing this piston?

Always follow the engine manufacturer’s service manual for proper installation procedures. Ensure the cylinder bore is within specification and properly honed before installation. Lubricate the piston rings, pin, and cylinder wall with clean engine oil during assembly. Use a piston ring compressor to avoid ring breakage, and verify ring end gap clearance according to Yanmar specifications. Torque connecting rod bolts to factory-recommended values using a calibrated torque wrench.

Q3: What is the expected service life of this aftermarket piston compared to OEM?

When properly installed and maintained with regular oil changes and air filter service, this aftermarket piston typically delivers service life comparable to OEM parts in normal operating conditions. The 6-month warranty covers manufacturing defects, but actual lifespan depends on factors such as engine operating hours, load conditions, fuel quality, and maintenance practices. Heavy-duty applications like excavators and bulldozers may experience different wear patterns than lighter applications like forklifts or generators.
