Abstract
An engine assembly includes an engine cover having a pump cavity through which fluid is pumped. A liner is configured to line the pump cavity to protect the engine cover from erosion due to the pumped fluid. The engine cover can be a composite material. The liner may be a composite material as well, or, in some embodiments, can be steel or another suitable material. A method of assembling an engine includes securing a liner to an engine cover so that the liner lines a pump cavity of the engine cover to protect the engine cover from erosion at the pump cavity.
