1. INTRODUCTION
This instruction sheet describes the use of Extraction/
Lance Reset Tools 843477-[ ] and 843996-2, -3, -4,
and -5. These tools are designed to remove MTE*,
Mod IV, Tandem Spring, and Mini Tandem Spring
contacts from housings and reset the overly
depressed contact locking lances of the removed
contact (see Figure 1). The two tool types are basically
the same except for the lance reset angles. The reset
angle of tool 843477-[ ] is 21° and the reset angle of
tool 843996-2, -3, -4, and -5 is 17°. This is to
accommodate the different designs of the locking
lances of Mod IV, Mod IV.v, Mod V contacts, as shown
in Figure 1 and Figure 2. The 843477-[ ] tools are used
with contacts having the old style locking lance design
and 843996-2, -3, -4, and -5 tools are used with the
contacts with the new style locking lance design.
Read these instructions thoroughly before attempting
to remove any contacts or resetting the locking lances.
