ROCKER ARM ASSEMBLIES MAINTENANCE - CONTINUED
INSPECTION - CONTINUED
Check rocker arm shaft stud for tightness. Ensure rocker arm shaft studs are tightened to 75-86 lb-ft (101-116 Nm).
Do not expand retaining clip more than 0.61 in (15.50 mm) when installing retaining clip. To do so could
result in equipment damage.
Position concave (dished side) of intake valve button toward adjusting screw ball.
Slide retaining clip (14), open end first, onto adjusting screw (12). Spread retaining clip slightly, if necessary, so open
end can pass over ball head of adjusting screw.
Insert tips of retaining ring pliers (13) between legs of retaining clip (14). Expand clip enough to insert groove on intake
valve button (15) onto leg arcs of retaining clip.
Adjusting screws with annular (Allen wrench) adjustment are used on intake (short arm) and injector
rocker arms. Hex head adjusting screws are used on exhaust (long arm) rocker arms.
Only exhaust rocker arm is shown.
Thread adjusting screw (12) into correct rocker arm (8), as noted during removal, and loosely install jamnut (11).
