INSTALLATION - Continued CAUTION Exhaust valves can be damaged if rocker arms are not properly aligned with exhaust valve stems. Each exhaust valve rocker arm controls two exhaust valves. Attached to the end of each exhaust valve rocker arm is a hinged engine poppet bracket (“bridge”). Each end of a “bridge” aligns with the top of a companion/mated exhaust valve stem. When lowering a rocker arm and “bridge” onto a set of two exhaust valve stems, make sure each end of the “bridge” is centered and squarely placed on the top of each exhaust valve stem. NOTE One exhaust valve rocker arm with rocker arm bridge is shown. 14. Lower two exhaust valve rocker arms (Figure 30, Item 2) with rocker arm bridges (Figure 30, Item 46) carefully onto two sets of companion/mated exhaust valve stems (Figure 30, Item 5). Make sure both mating ends of rocker arm bridge (Figure 30, Item 46) are centered and squarely positioned on top of exhaust valve stems (Figure 30, Item 5). 5 2 46 MAINT_471 Figure 30.
