Multiquip 11477011020 Cylinder Head Assembly - OEM Replacement Part for Rammers

The cylinder head assembly is a critical engine component that seals the combustion chamber and houses the valve train for the Yanmar L40ADRM diesel engine. This OEM assembly ensures proper compression, fuel injection timing, and heat dissipation necessary for the powerful compacting performance of diesel-powered tamping rammers.

The MT76D rammer is equipped with an air-cooled, four-cycle Yanmar L40ADRM diesel engine rated at 4.2 HP maximum output (3.1 kW). This engine operates at a maximum governed speed of 3,300 rpm and delivers 700 impacts per second with an impact force of 3,600 lbs. per blow. The cylinder head assembly is integral to maintaining the 12.14 cubic inch (199cc) piston displacement and 2.67 x 2.16 inch bore and stroke specifications. Proper cylinder head function is essential for the forced air cooling system and overall engine performance during soil compaction applications including road work, embankments, and backfilling operations.
