FAQ

Q: How can I confirm this bush fits my Yanmar 4TNV98 engine?
A: Please verify the part number stamped on your old connecting rod bush. It should read 129900-23910. This part is specifically designed for the 4TNV98 model. If your part number differs, please contact us with your engine serial number for cross-referencing.

Q: Is professional installation required for this component?
A: Yes. Installing a con rod bush requires precision tools (such as a press and a reamer or sizing tool) to ensure the correct interference fit and final internal diameter. We strongly recommend installation by a qualified diesel engine technician to avoid engine damage.

Q: Does this part require any special lubrication during installation?
A: Yes. Before installation, apply a thin layer of clean engine assembly lube or engine oil to the outer diameter of the bush and the connecting rod bore. After installation, ensure the oil hole in the bush is properly aligned with the lubrication passage in the connecting rod to guarantee oil flow to the piston pin.
