VALVE ROCKER ARM SHAFT
BENCH PROCEDURES
[213 LP]
Rocker Arms
Early-production E-Tech™ engines used the
older style rocker arms of the E7 engine. Effective
second quarter 1997, both models use a newly
designed rocker arm (Figure 213) where the
slipper end wear surface is a hardened, headed
pin, pressed into the rocker arm.

Disassembly (without/with Engine
Brake)
For early-production engines, six C-clips are used
to retain the rocker arms in position. For later-
production, the four inboard C-clips and washers
are replaced with two spacer tubes to properly
position the rocker arms.
Refer to Figure 214 and Figure 215. The shaft
assembly is disassembled as follows:
1. Remove the C-clip and flat washer from one
end of the shaft.
2. Remove the outer rocker arm and spring
washer.
3. Press the mounting bracket from the shaft.
Use care not to drop the assembly as the
bracket is removed.
4. Remove the second spring washer, rocker
arm, flat washer and C-clip or spacer tube, if
so equipped.
5. Repeat steps 1 through 4 to remove the two
remaining rocker arm sets from the shaft.
6. Remove the adjusting screws and jam nuts
from the rocker arms.
Inspection
Inspect all components of the rocker arm and
bracket assembly for evidence of damage or
wear. Replace as necessary.
