FAQ

Q1: Does this kit include piston rings and cylinder head gaskets?
A: This part is specifically a Cylinder Liner Kit. It includes the cylinder liners for the 4TNV98 engine. It does not typically include pistons, rings, or gaskets. For a complete overhaul, you may need to order a full “Overhaul Gasket Kit” and “Piston & Ring Set” separately. Please check the product listing details or contact us to confirm the exact contents.

Q2: How can I be sure this liner kit will fit my Hyundai R80-7 excavator?
A: The best way to confirm compatibility is to check the engine model plate on your machine. This kit is designed for the Yanmar 4TNV98 engine. While it is the standard engine for the Hyundai R80-7, Hitachi SH75X-3, and Daewoo DH80-7, we recommend visually comparing the new liner to your old one or providing your engine serial number to our support team for final verification before installation.

Q3: What is the proper installation procedure for these liners?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: thoroughly cleaning the cylinder block bore, checking the block deck surface for flatness, lubricating the new liner O-rings, carefully pressing the liner in by hand (avoiding force), and ensuring the liner protrusion height is within the manufacturer’s specification (typically 0.02-0.10mm above the block deck). A torque plate should be used for final honing if required. Always follow the Yanmar 4TNV98 service manual for precise torque specs and procedures.
