SVC 5-22
22. Use the lance release tip of an AMP pin extrac-
tion/lance reset tool (8710-1542) to remove the
appropriate pins (from the old harness) from
connector P8. (The tool features a lance re-
lease tip and a lance reset tip. The lance re-
lease tip is used to depress the pin locking
lance to extract the pin from a connector. The
lance reset tip positions a locking lance to its
proper height to ensure retention of the pin in
the connector.)
23. Prepare the pins corresponding to the replace-
ment stepper motor by adjusting their locking
lances using the lance reset portion of the tool.
24. Insert the pins for the replacement stepper mo-
tor into their appropriate locations in the plug,
making sure the locking lance on each pin
seats into its hole through the side of the plug.
25. Gently pull on the wire to ensure that the pin is
locked in the connector.
26. Insert the plug in its receptacle (P8) on the main PCB. (The plug is keyed and can only be in-
serted one way.)
27. Replace the panels removed at the beginning of this procedure.
28. Connect any gas supplies disconnected in step 4 of this procedure.
29, Restore power to the instrument.

sembly completely.
