ABSTRACT:
The valve spring wear plate is proposed for use in a locomotive engine cylinder head to protect the areas of the cylinder head each acting as a valve spring seat from becoming grooved by the action of the spring thereagainst. The wear plate accommodates one spring seat at each end thereof, the two end portions being connected together by a narrow bridge portion, the bridge portion keeping the ends from rotational movement caused by action of the spring thereagainst.
