F. Measure the Sensor Gap (Jack Procedure)
NOTE: This is the preferred method for measuring the sensor gap.
____ S 492-052
(1)
Make sure the downlocks are installed on the nose and main landing gear (AMM 32-00-20/201).
S 492-053
(2)
Make sure the chocks are below the wheels.
S 862-040
(3)
Lift the nose of the airplane until the wheels are off the ground (AMM 07-11-02/201).
S 862-041
(4)
Make sure the steering for the nose landing gear is in the center position.
S 222-042
(5)
Measure the clearance between the sensor and the sensor target (refer to Fig. 201).
S 862-043
(6)
If the distance is not the same, do the task to adjust the sensor gap.
G.
Measure the Sensor Gap (Alternate Procedure)
NOTE: Use this method when you cannot use a jack on the nose gear
____ and both the primary and alternate gaps are questionable. You should remeasure the sensor gaps when the airplane can be lifted on jacks.
S 862-058
(1)
Make sure the steering for the nose landing gear is in the center position.
S 032-059
(2)
Disconnect the nose gear upper torsion link from the lower torsion link at the apex bolt (AMM 32-21-09/401).
NOTE: Do the steps in the removal task which removes the apex bolt

(3) Attach the inclinometer to the nose gear upper torsion link
(Fig. 202).
NOTE: Attach the inclinometer to the upper outer section next
____
to the pivot pin.
S 982-061
(4) Adjust the nose gear upper torsion link so the inclinometer shows
58.5 degrees from vertical.
NOTE: Use the torsion link shim to hold the weight of the
____
torsion link. (Fig. 202)
S 222-062
(5)
Measure the clearance between the sensor and sensor target.
S 832-063
(6)
If the sensor gap is not within tolerance (Fig. 201) do the task to adjust the sensor gap.
S 092-064
(7)
Remove the torsion link shim.
S 432-065
(8)
Connect the upper and lower torsion links (AMM 32-21-09/401).
NOTE: Do the steps in the installation task which installs the apex
____ bolt to connect the upper and lower torsion links.
H. Measure the Sensor Gap (Alternate Procedure)
NOTE: Use this method when you cannot use a jack on the nose gear.
____ This method can be used when only one sensor has indication of being out of tolerance.
S 862-066
(1)
Make sure the steering for the nose landing gear is in the center position.
(2)
Attach a tag to the sensor which may need adjustment.
