FAQ

Q1: Will this cylinder block fit a Yanmar 4TNV88T engine with a turbocharger?
A: Yes, this block (729602-01560) is designed for both the naturally aspirated 4TNV88 and the turbocharged 4TNV88T. The core casting and machining are identical. However, you must use the correct piston and ring set for the turbo application to handle higher compression and thermal loads.

Q2: What is the recommended installation procedure for this block?
A: Always use new head bolts, main bearing bolts, and gaskets. Torque the main bearing caps to 88 Nm (65 lb-ft) in the specified sequence, and the cylinder head bolts to 127 Nm (94 lb-ft) in three stages. We recommend checking the cylinder bore for any shipping debris and lightly oiling the cylinder walls before piston installation.

Q3: How do I verify the correct part number for my engine?
A: Locate the engine serial number (stamped on a flat boss on the side of the block near the starter motor). Cross-reference this with the Yanmar parts catalog. The 729602-01560 block supersedes older revisions like 729602-01550, but we recommend confirming compatibility with your specific engine serial number to avoid fitment issues.
