FAQ

Q1: How do I verify this overhaul kit fits my Yanmar 3TNV80 engine?

Check the engine model number stamped on the engine block or identification plate. The 3TNV80 will be clearly marked. Also verify the engine serial number and measure the cylinder bore diameter (standard size is 80mm). If your engine has been previously rebored or sleeved, you may require oversized components. Contact our technical support team with your engine details for confirmation.

Q2: What is the typical installation time for this overhaul kit?

Installation time varies based on experience and equipment condition. A skilled diesel mechanic can typically complete a full engine overhaul using this kit within 8-16 hours for a mini excavator engine. This includes disassembly, inspection, installation of new components, and reassembly. Allow additional time for engine break-in and testing after installation.

Q3: What maintenance is recommended after installing this rebuild kit?

After installation, follow a strict break-in procedure: run the engine at varying loads for the first 50 hours, avoiding prolonged idling or full-load operation. Change engine oil and filter after the first 50 hours of operation. Check valve clearances and cylinder head bolt torque after initial heat cycles. Thereafter, follow standard Yanmar maintenance intervals for oil changes, filter replacements, and inspections to maximize the life of your rebuilt engine.
