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.

All dimensions are in millimeters [followed by

inches in brackets]. Figures and illustrations are for
