FAQ

Q1: How can I confirm this eccentric shaft is the correct part for my specific Yanmar 3TNV70 engine?
A1: The most reliable method is to cross-reference the part number stamped on your original shaft. This part replaces Yanmar 119515-14580. We also recommend consulting your engine’s service manual or contacting us with your engine’s full model and serial number for verification.

Q2: What is the role of the eccentric shaft in the 3TNV70 engine, and what are signs it needs replacement?
A2: The eccentric shaft, or balancer shaft, is crucial for reducing engine vibration by counteracting the forces produced by the pistons and crankshaft. Signs of failure include excessive engine vibration or knocking noises, oil leaks from the shaft seals, or visible scoring/wear on the shaft journals. Timely replacement prevents further damage to bearings and the engine block.

Q3: Do you provide technical support for installation and part sourcing for complete engine overhauls?
A3: Yes. As a B2B specialist, we offer technical data sheets for critical components. For comprehensive engine rebuilds, we can supply matched component kits—including gaskets, bearings, and seals compatible with this eccentric shaft—ensuring all parts work in harmony.
