Dismounting and mounting of the chain roller
To dismount the chain roller, the chain tubes
need to be removed. See also hints on replac-
ing the chain tubes (page 53)
The chain roller is mounted with a special
high strength screw of the German strength
grade 12.9 and it may only be replaced by a
screw of the same type and strength.
The chain roller is not symmetrically shaped;
the recessed side of the chain roller has to
face to the frame, the flat (logo) side out-
wards.
