24. An AMP pin extraction tool (8710- 0614) is re-
quired to properly remove pins from connector
J9. The tool features a sleeve to release the pin
locking lance, and a plunger to eject the pin
from the plug. The following steps detail how
to remove the pins from the connector.
a. Slide the sleeve portion of the tool straight
into the pin to be removed from the con-
nector until it is fully bottomed.
b. At the same time, allow the plunger to be
pushed back by the pin.
c. Rotate the body of the tool to ensure it is
fully bottomed, and to ensure the pin lock-
ing lance is released.
d. Holding the body of the tool firmly in place
(fully inserted into the plug), depress the
plunger to eject the pin from the connector.
e. Remove the tool from the plug.
25. Insert pins from the new valve into their appropriate
locations in the plug, making sure the locking lance on
each pin seats into the plug.
26. Gently pull on the wire to ensure it is locked in the plug.
27. Insert the plug in its receptacle J9 on the main circuit board.
Notice that the plug is keyed and can only be inserted
one way.
