Claims18
An engine, comprising:
- an engine cover for covering internal components of the engine;
- a rotary shaft;
- an end bearing assembly having a flange mounted to an external surface of the engine cover and a bearing portion for supporting an end of the rotary shaft;
- and
- an oil delivery system comprising a tube coupled to a first port on the end bearing assembly for delivering pressurized oil to surfaces of the rotating bearing from a source of pressurized oil of the engine.
