on Model 81. Dashed line terminal outline represents "J" Hook,
available on Model 82.
Note: For units with dual concentric shaft styles, a
2.54 (.100) spacer is added between the module(s) driven
by the outer shaft and those driven by the inner shaft.
For G, K, or V shafts, add the spacer between
modules 1 and 2. For L or M shafts, add the spacer
between modules 2 and 3. For N or P shafts, add the
spacer between modules 3 and 4.
