Yanmar Cylinder Head


Cylinder head has a key role in diesel engines. The cylinder head sits on the engine and closes off the combustion chamber. Cylinder head provides the mounting structure for various components such as the inlet and outlet exhaust valves and a number of moving parts such as camshaft.

Cylinder heads have to be robust to withstand high pressures and very high temperatures while retaining their shape and form to seal the cylinder block via the head gasket.

If there is a drop in coolant levels, oil levels, and engine performance, and smoke coming out of the exhaust in a diesel engine most probably the cylinder head of the diesel engine is faulty.

Yanmar cylinder heads are manufactured with the latest technology to withstand high temperature and pressure. Yanmar cylinder heads are fixed in position and sealed with the head gasket, cylinder heads don’t suffer the same wear and tear as moving parts of diesel engine. That is why Yanmar cylinder heads do not need to replace with the new one in short term.

However, if there is a failure in Yanmar cylinder head that is uncoverable it should be replaced with the new one in order to avoid the costly repair of other parts that will be failed due to the faulty cylinder head.
