FAQ

Q1: How do I confirm this cylinder liner will fit my specific Yanmar engine?
A1: The most reliable method is to cross-reference the part number stamped on your original liner or listed in your engine’s service manual with our listed OEM numbers (129901-01198 or 123950-01100). Also, verify your engine’s complete model designation (e.g., 4TNV106-T).

Q2: What preparation is required before installing this new cylinder liner?
A2: Proper installation is critical. The engine block counterbore must be thoroughly cleaned and inspected for damage. The new liner should be checked for correct dimensions. Follow OEM service procedures for installation, which typically involve chilling the liner and heating the block, and ensure proper protrusion above the block deck is achieved and measured.

Q3: Do you provide technical support or documentation with the part?
A3> While we supply the component to OEM specifications, detailed installation procedures should be obtained from the official Yanmar service manual for your specific engine model. We can provide general dimensional data and the quality inspection report for the part upon request.
