(6)
Do the deactivation procedure for the thrust reverser for ground maintenance (AMM 78-31-00/201).
S 225-040-N00
(7)
Put a feeler gage between the face of the actuator lock proximity sensor and the target to measure the clearance.
NOTE: The clearance between the face of the proximity sensor and
____ the surface of the target must be 0.010 to 0.040 inch.
S 825-041-N00
(8)
Install or remove the shims below the target to get the correct target clearance.
