FAQ

Q1: Will this set fit my Yanmar 4TNV98 engine if the serial number is from 2015?

Yes, the 4TNV98 engine platform remained consistent from 2000 to 2020. However, we recommend checking your engine’s serial number against our compatibility chart. The cylinder liners and pistons are designed for the standard 98 mm bore, but if your engine has been previously rebored, you may need oversized components. Contact our technical team with your engine SN for verification.

Q2: How difficult is the installation of this overhaul set?

This is a professional-grade overhaul kit requiring mechanical expertise. Installation involves disassembling the engine, removing old liners and pistons, cleaning the block, and reassembling with new components. We recommend a certified diesel mechanic with experience in Yanmar engines. The gasket kit includes all necessary seals, but you may need additional tools (e.g., liner puller, ring compressor).

Q3: What maintenance is required after installing this kit?

After installation, follow a strict break-in procedure: run the engine at low idle for 50 hours without heavy loads. Change the oil and filter after the first 50 hours. Use API CH-4 or higher grade oil (15W-40 recommended). Regularly check coolant levels and valve clearances every 500 hours. This will ensure optimal performance and longevity of the new components.
