(corresponds to about 8

In countries other than the GDR, a gear oil with sinii-
lar viscosity values and properties should be used.

Lubricants for Cycle
Parts
The swing arm bearing and the worm for clutch oper-
ation must also be lubricated with GL 60 g e a r o i l.
(Oil-filled greasc gun: swing arm bearing to be lubri-
cated thoroughly until oil emerges from the lubrication
points:
WOITII
for clutch actuation to bc lubricated by
2 to
3
strokes.)

antifriction bearing grease:
steering bearing. wheel bearings, bearing for
~.car-\vheel drive, secondary chain, brake cam.
brake shoe bearings, and speedometer drive (the
latter only \\.hen being n~ounted or repaired).
This antifriction bearing grecse has a pour point of
about
130

150
"C,
can be used for a temperature
range f~wn
-30
to
+lOOaC,
and is water-resistant ct

'C.
in countries other than the GDR, an antifriction bear-
ing grease of similar characteristics should be used.
2.5.
Shock-absorber Fluid
For the telescopic fork and the spring-loaded suspen-
sion units, a shock-absorber fluid of a viscosity of 8 to
11 cSt (corresponds to 1.65 to 1.9?
"E)
at 50 "C should
be used.
The damping characteristics of the telescopic fork and
the spring-loaded suspension units are based on this
viscosity. Springing and roadability will be impaired
if
shock-absorber fluids of a different viscosity will be
used.
2.6.
Contact Breaker Lubrication
For contact breaker lubrication, the special oil for igni-
tion circuit breakers, in the GDR known as
"Unter-
brijl", should be used; it possesses a viscosity of from
500 to 1,300 cSt at 50 OC.
If this special oil is not available, a high-viscosity gear
oil of similar viscosity properties can
be
used.

Disassembly
of
the
Engine
Remove the closing plate and the dynamo cover,
dirc
connect the cables from the dynamo (disconnect the
plugged connections).
If the identacation colours of the various cables
are
not clearly discernible, it
is
advisable, especially for
amateur ccnstructors, to attach paper slips with mark-
ings
(D+,
DF
and frame) to
the
cables to save
the
work of measuring them for reassembling,

Use puller 02-MW 39-4 or a screw M 10x100 for re-
moving the armature. By means of other tools,
eg.
a
claw-type'puller, either the winding will be damaged
or the segments will be deformed.
Keep the plate disk ("key") in a safe place!
