NOTICE
WARNUNG
Always use new mono hook circlips. Retaining
rings which are used or have already been in-
stalled have insufficient tangential tension, can
twist and consequently abrade the groove in the
piston.
NOTICE
WARNUNG
The position of the mono hook circlip is defined
by the recess in the piston. The open side of the
mono hook circlip must be opposite the piston
crown when installed.
Step
5 Install the piston pin circlip with installa-
tion tool part no. 877802.
To do this, press the mono hook circlip
into the groove of the installation sleeve
and push the guide tool into the installa-
tion sleeve.
6 Push the installation sleeve onto the in-
stallation tool.
7 Push the installation tool into the position
gauge and press the ring forwards as far
