FAQ

Q1: Is this cylinder block a direct fit for my Yanmar 3TNV88 engine?
This block is manufactured to OEM size specifications for the 3TNV88 series. However, engine variants (e.g., 3TNV88-B, 3TNV88-S) may have minor differences in oil gallery routing or mounting bosses. We recommend comparing your original block’s casting numbers or contacting us with your engine serial number for compatibility confirmation before ordering.

Q2: What additional parts are needed for a complete engine rebuild with this block?
A full rebuild typically requires a cylinder head gasket set, piston and ring assembly, bearings (main and connecting rod), oil seals, and possibly a water pump. We can supply compatible gasket kits and internal engine parts for the 3TNV88 upon request. Ensure all old gasket material is removed and surfaces are clean before installation.

Q3: How should I store this cylinder block if not installed immediately?
Store the block in a clean, dry environment at room temperature. Keep it in its original packaging to protect machined surfaces from dust and moisture. Apply a light coat of anti-rust oil on exposed cylinder bores and deck surfaces if storage exceeds 30 days. Avoid stacking heavy objects on top of the block to prevent distortion.
