3.11.8.1) Rocker arm with plastic bushing
See Figs. 72-78, 72-79 and 72-80.
In the case of plastic rocker arm bushings (2), it must be
ensured that the bushing is of slide fit design. After installa-
tion, it must still be possible to rotate it against the rocker arm
bore.
To allow this, the plastic bushing is equipped with a circular
groove (1) on its circumference via which it is supplied with
oil. The bushing can be installed in any position.
See 72-00-00 sec. 4.
The plastic bushing must be adequately oiled before
installation.
■
CAUTION: When installing the rocker arm, it is impor-
tant to ensure that the bushing (2) is fitted
together with the rocker arm.
See SI-912-009 /SI-914-010,“Introduction
of a new rocker arm bushing“, latest
issue.
◆
NOTE:
Oversize rocker arm shafts and rocker arm
bushings are available for repairing the
rocker arm bearing in the cylinder head.
Ensure that the correct rocker arm bushing
is fitted. For easy identification, the over-
size rocker arm bushing, part no. 933397,
has two opposed bores (3).
