The "Maintenance" chapter
describes work involving the
replacement of wear parts that
can be performed with mini-
mum effort.
The types of threaded fastener
used for the various compo-
nents are listed on (
b
128).
You can use this chart to set
aside the required tools.
If special tightening torques
are to be taken into account
for assembly, these are also
listed. Screw connections for
which there is a suitable tool in
the toolkit are marked addi-
tionally. If you are interested in informa-
tion on more extensive work,
we recommend the repair
manual on CD-ROM which
applies to your particular
motorcycle. You can obtain a
copy of this from your author-
ised BMW motorcycle dealer.
