FAQ

Q: Is this a complete engine rebuild kit?
A: This is a comprehensive top-end overhaul kit containing the cylinder liner, piston assembly (piston, pin), and piston ring set. For a full rebuild, you will also need to source additional components like bearings, gaskets, and the cylinder head kit as required by your engine’s condition.

Q: How do I confirm this kit fits my specific SD-series engine?
A> The most reliable method is to cross-reference the part numbers stamped on your existing components (especially the cylinder liner and piston crown) with the numbers provided: 11012-L2002 and 12010-T6202. Matching the engine model (SD22/23/25) is also essential.

Q: What is the recommended procedure for installing these components?
A> Professional installation is critical. Always follow the engine manufacturer’s service manual for specifications on liner protrusion, ring end-gap, piston-to-wall clearance, and proper assembly lubrication. The cylinder block should be inspected for integrity, and honing may be required for proper ring seating.
