ROCKER LEVER, EXHAUST D.S.
Exhaust rocker lever, drive side, for the cylinder head rocker box assembly, part number 71-1290 (also E11290).
This is the exhaust rocker lever, drive side, part number 71-1290, also known under the older E11290 designation. It's a cylinder head component that lives in the rocker box, part of the valve gear that operates the exhaust valve. The rocker lever pivots on its shaft and transfers motion from the pushrod to the valve, so it takes wear at both the pushrod cup end and the valve tip end over time.

It shows up in the catalogs under the CYLINDER HEAD AND ROCKER BOXES figure, with appearances spanning 1970 to 1972 in our records. If you're rebuilding a rocker box assembly, check the wear pattern on the pad that contacts the valve stem, and inspect the bore where it rides on the rocker shaft for play.
