sensors. 2) If the clearance is not in the limits, do the next step: a) Add or remove washers from between the head of the target and the surface it is attached to.
NOTE: If more or less washers under the target does
____ not give the correct adjustment, you can add or remove washers from between the nut attached to the sensor and the bracket on the lock link.

2) If the clearance is not in the limits, do the steps that follow: a) Manually apply a force to the uplock hook to release
the lock on the hook. b) Remove the nut that holds the target into the flange. c) Add or remove washers below the target head to get the
correct clearance. d) Install the nut and washer(s) on the target and tighten
the nut. e) Manually apply a force to the uplock to lock the hook. f) Make sure the clearance between the sensor and the
target is correct (Fig. 202). g) If the clearance is not correct, adjust the sensor clearance again. h) Manually apply a force to the uplock and release the lock on the hook.

(3) Do the steps that follow to adjust the door closed sensor for the landing gear (Fig. 203):
WARNING:_______OBEY THE INSTALLATION PROCEDURE FOR THE DOOR LOCKS. THE DOORS OPEN AND CLOSE QUICKLY. THE MOVEMENT OF THE DOORS CAN CAUSE INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT.
(a) Open the doors for the landing gear and install door locks (AMM 32-00-15/201).
NOTE: The doors for the nose and main landing gear open at
____
the same time by ground release.
(b) Apply a thin layer of talcum powder to the surface of the sensor that gets an input from the target.
CAUTION: DO NOT APPLY MORE THAN 1/8 INCH OF MODELING CLAY TO THE
_______ SURFACE OF THE TARGET. TOO MUCH CLAY WILL BEND THE SENSOR BRACKET WHEN THE DOORS FOR THE MAIN LANDING GEAR ARE CLOSED.
(c) Apply two strips of soft modeling clay that is 1/8-inch thick to the surface that gets an input from the the target. 1) Put one strip at each end of the surface. 2) Keep sufficient clearance to permit the clay to become
larger.

NOSE GEAR PROXIMITY SENSORS - MAINTENANCE PRACTICES
___________________________________________________
1. General_______
A. This procedure contains five tasks for the proximity sensors for the nose landing gear. The first task is for the removal of the proximity sensor. The second task installs the proximity sensor. The third task adjusts the clearance between the sensor and target. The fourth task does a test of the proximity sensor. These first four tasks are for the proximity sensors that follow. The fifth task is an installation procedure for the nose gear target.
