Description
Overview:
The Cylinder Head for Robin/Subaru DY23 and DY27 diesel engines is a precision cast aluminium alloy component that seals the combustion chamber and supports the top end of the engine. It maintains correct compression, directs intake and exhaust flow, and manages heat transfer under continuous duty. Built to match OEM specification 243-13001-81, it aligns accurately with factory studs, dowels and gaskets to help preserve performance and reliability. Suitable for a wide range of light construction and garden machinery powered by DY-series engines, such as plate compactors, generators and water pumps, it is designed to handle high temperatures and pressures. A true like-for-like replacement for a worn, cracked or warped head, it helps restore smooth running, efficiency and dependable starting on DY23 and DY27 machines.
Key Features:
- OEM reference 243-13001-81 for accurate identification and fit
