The Deutz BF4M2012 cylinder head (OEM: 04285994) is a premium cast iron component designed for 4-cylinder engine architectures.
It is engineered to resolve overheating and low oil pressure issues in Volvo EC135B and Bomag Compactor machinery.
In stock for global export.
Powering the Deutz BF4M2012 engines found in Volvo EC135B excavators and heavy-duty road machinery, our cylinder head (OEM: 04285994) serves as a robust 4 cylinder engine head replacement. This casting is designed for intense industrial cycles, ensuring maintenance supply for global distributors and large-scale fleet maintenance programs.
Failures such as a spun bearing, chronic overheating, or low oil pressure often originate from structural fatigue or coolant passage blockage in the original head. Replacing a warped or cracked unit with this structurally verified BF4M2012 head restores factory compression and ensures consistent performance in demanding environments like road paving and compacting.
