FAQ

Q1: How can I confirm this connecting rod will fit my Yanmar 4TN100 engine?
A: You should first verify your engine model plate. The 4TN100 is a 4-cylinder engine, while the 3TN100 is a 3-cylinder. This connecting rod is designed for both, but we recommend removing your old connecting rod and comparing the center-to-center length, pin bore diameter, and big-end width with the specifications provided. If you have a specific OEM part number from your old rod, please contact us to cross-reference it.

Q2: Is this connecting rod a direct replacement for the Yanmar OEM part?
A: Yes, this part is manufactured to OEM size and specifications, making it a direct replacement in terms of dimensions. However, as an aftermarket part, it is not manufactured by Yanmar. It is a high-quality alternative designed to meet or exceed the original performance standards.

Q3: What maintenance should I perform when installing a new connecting rod?
A: When replacing a connecting rod, it is critical to also inspect the crankshaft journal for wear or scoring. The connecting rod bolts should be tightened using a torque wrench to the manufacturer’s specified torque setting (usually in the range of 40-60 Nm for small diesel engines, but verify with your service manual). Always use new rod bolts and lubricate the threads and bearing surfaces with clean engine oil during assembly. It is also recommended to replace the connecting rod bearings and piston pin bushings at the same time.
