Rocker exhaust, left
Left-side exhaust rocker arm for the cylinder head, listed for the 1983 model year.
71-7690 is the left-side exhaust rocker arm, listed in the cylinder block and head section of the parts book. A rocker arm like this pivots on the rocker shaft up in the head, taking the push from the pushrod on one end and pressing down on the valve stem on the other, opening the exhaust valve as the cam lobe comes round.

This one shows up in the catalog for the 1983 model year, on the left-hand exhaust side of the head. If you're rebuilding a head or chasing valve gear noise, this is the part that lives right at the top, working the exhaust valve open and shut on every revolution.
We only have the one catalog listing on this number, so if you've got a different year machine, give us a call and we'll confirm before you order.
