Abstract:
An engine roller lifter for use in a leak-valvetrain of an internal combustion engine includes a body, a roller and an anti-rotation plug. The body includes an outer peripheral surface configured for sliding movement in a bore provided in the engine. The bore is supplied oil by an oil passage communicating therewith. The body defines an opening. The roller bearing is rotatably mounted to the body and is configured for rolling contact with an engine camshaft. The anti-rotation plug is received at the opening and has a plug body including an anti-rotation protrusion that extends radially beyond an outer peripheral surface of the plug body. The anti-rotation plug can be staked into the opening of the body.

Claim (Index 18):
A method of producing an engine roller lifter for use in a valvetrain of an internal combustion engine, the engine roller lifter having a lifter body having an outer peripheral surface configured for sliding movement in a bore provided in the engine, the lifter body defining an opening, the method comprising:\n slidably advancing an anti-rotation plug into the opening of the lifter body, the anti-rotation plug having a cylindrical plug body that includes first and second face surfaces formed on opposite sides of an anti-rotation protrusion; and staking the anti-rotation plug whereby the cylindrical plug body expands radially outwardly at diametrically opposed positions to attain an interference fit with the opening of the lifter body.
