NOTE: The following Figures describe the common
installation of all clutches. For it, the housing cover,
combined with special tool (Handle 5870 260 010) is
needed. The reassembly of single clutches without
housing cover and handles is extremely difficult
because of the installation conditions. Besides, there
is the danger of injury.
1. Insert all outer bearing races into the housing cover until
contact is obtained.
NOTE: In the case that already run bearings are
reused, pay attention to the allocation of the
outer bearing races, see also Note,
