Rotax 915 i A series Maintenance Manual page 243

ATTENTION
Always use new mono hook circlips. Circlips
which are used or have already been installed
have insufficient tangential tension, can twist
and consequently abrade the groove in the
piston.
ATTENTION
The position of the mono hook circlip is de-
fined by the recess in the piston. The open side
of the mono hook circlip must be opposite the
piston crown when installed.
Step Procedure
5 Install the mono hook 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 installation 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
as it will go.
