ARMY TM 9-2815-254-24
AIR FORCE TO 38G1-94-2
FIGURE 3-57. Rocker Arm Correction
Use compressed air to thoroughly clean rocker arm shaft (18, FIGURE 3-52) and rocker arms (12, 14, 16,
and 17) oil ports.
Coat rocker arm shaft and rocker arm bushings with engine lubricating oil (MIL-L-2184).
Rocker arm shaft (18) positioning is done by a cutaway machined on
shaft end. Install retaining plates (13) and shaft (18) so that cutaway
faces mating bolt stem.
Rocker arms (12, 14, 16, and 17) each have a different shape. Be sure
to install them in their correct location (refer to FIGURES 3-52 and 3-53)
as viewed from front.
Install dust plugs (11) in each end of shaft (18).
Install adjusting screw (20) and nut (19) in each rocker arm so they are in a loosened condition.
