The following subsections explain how to config-
ure the end gears, which are accessed by remov-
ing the end cover.

The end gears are preset by the factory in this
configuration, which is only used for power feed-
ing. Mesh the top 20T A gear with the 80T B gear,
and mesh the 20T C gear with the 80T D gear
(see Figure 55).
