Abstract
A relatively thin, post-mounted valve lever having a ball bearing pivot for operating an intake or exhaust valve of an internal combustion engine and having a lateral bearing surface which slidably engages aligned spaced lateral surfaces on a wide supporting post which maintain the rocking plane within the valve lever. A retainer is disposed on the top side of the post and extends into the central opening in the valve lever to prevent the rocker arm, post, and ball bearing from becoming disassembled.
