General
This chapter provides basic instructions for removal, service and installation of a flexible coupling kit,
with a fan attached. This flexible coupling kit is designed for use with single-bearing generator sets.
Figure 1 shows a rear view and side view of the flexible coupling assembly. The primary function of this
assembly is to couple a Hobart generator set to a diesel engine. The flexible coupling assembly
compensates for slight misalignment between the engine and the generator, due to manufacturing
tolerances. A split taper bushing secures the coupling to the generator’s armature shaft. (See Fig. 3 &
4).
