2. DESCRIPTION (Figure 1)
The extraction tool consists of a spring-loaded metal
tip with an integral plunger mounted to a plastic handle
with an interlock lever. When the interlock lever is
depressed, the plunger is held until the contact locking
lances are depressed by the tip. After the lever is
released, the plunger is released, permitting the
contact to be pushed out the rear of the housing.
3. EXTRACTION PROCEDURE (Figure 3)
1. Determine the contact to be removed and grasp
the wire attached to that contact.
2. Move the contact forward as far as possible by
p
ushing the wire toward the housing.
If pushing the wire by hand is difficult, use Insertion
Tool 91002-1.
3. Depress the extraction tool interlock lever and
insert the tip of the tool into the contact cavity in the
mating face of the housing. Make sure that the tip is
completely bottomed in the cavity.
4. While holding the extraction tool in position and
pulling
back on the wire, release the interlock lever
and push the tool handle forward. The wire and
contact should pull out of the housing.
