FAQ

Q1: Is this 3TNA68 eccentric shaft a direct replacement for my Yanmar engine?

This eccentric shaft is specifically designed for Yanmar 3TNA68 diesel engine models. It is manufactured to OEM size specifications, meaning it should be a direct bolt-on replacement. However, we strongly recommend verifying your engine’s serial number and comparing the physical dimensions with your existing part before installation. If you have any doubts, please contact our technical support team with your engine details for compatibility confirmation.

Q2: What maintenance is required for the eccentric shaft after installation?

The eccentric shaft itself requires no direct maintenance after proper installation. However, we recommend checking the following during routine engine service: ensure proper lubrication oil flow to the shaft area, inspect for unusual wear patterns every 500 operating hours, and verify that timing marks align correctly during any engine timing adjustments. Always use manufacturer-recommended lubricants and follow Yanmar’s maintenance schedule for your specific engine model.

Q3: How do I ensure correct installation of the 3TNA68 eccentric shaft?

Installation should be performed by a qualified diesel mechanic following Yanmar’s service manual for the 3TNA68 engine. Key installation steps include: clean the mounting surface thoroughly, apply appropriate assembly lubricant, align timing marks precisely, torque mounting bolts to manufacturer specifications, and rotate the engine manually to verify smooth operation before starting. We recommend using new gaskets and seals during installation. If you need installation guidance, we can provide video inspection support upon request.
