Abstract
A retrofit roller bearing pivot assembly for a rocker arm of an internal combustion engine valve gear. A mounting stud or post threaded on one end for attachment to the engine has a fulcrum member received thereover and registered against a head formed thereon with transversely extending oppositely disposed cylindrical bearing surfaces. A roller bearing race is received on each of the bearing surfaces and a semi-cylindrical sleeve member has the post received therethrough and has concave portions on opposite ends thereof journalled on the fulcrum bearing surfacers. The sleeve is retained against the bearings by a spring clip received over the end of the post and engaging ledges on the sleeve. The fulcrum is retained in registration on the post by a contoured supporting spacer held in place by a suitable snap ring received over the post threads. The assembly is sized to drop between the side wall of a cupped rocker arm.
