FAQ

Q1: Will this bearing set fit my Yanmar 3TNV82 engine?

A: Yes, this bearing set (Part # 129813-21000) is specifically designed for the Yanmar 3TNV82 and 3D82 engine series. The connecting rod bearing has a 43mm inner diameter, and the main bearing has a 47mm inner diameter. Please verify your engine model and existing bearing dimensions to ensure a perfect match.

Q2: What tools are required for installation?

A: Installation requires standard engine rebuilding tools, including a torque wrench, bearing installation tool (or a soft-faced mallet), and Plastigage for verifying bearing clearance. We recommend consulting the Yanmar service manual for your specific engine model for detailed torque specifications and procedures.

Q3: What is the recommended maintenance after installing these bearings?

A: After installation, perform a break-in period of 50 hours under moderate load. During this time, monitor oil pressure and temperature closely. Change the engine oil and filter after the break-in period to remove any initial wear particles. Use high-quality engine oil meeting Yanmar’s specifications (typically API CI-4 or higher) for optimal bearing life.
