Procedure

 S 214-011
 (1)  
Examine the antiskid transducer connector for broken wires or other damage. Replace the connector if necessary. Refer to Chapter 20, Wiring Diagram Manual, for connector replacement information.

 S 424-012

 (2)  
Put the dog (11) on the transducer rotor shaft and install the cone washer (10) with the bolt (9). Tighten the bolt (9) to 20-25 pound-inches.

 S 424-024

 (3)  
Install lockwire.

 S 434-013
 CAUTION: DO NOT TWIST THE WIRE HARNESS WHEN YOU REMOVE OR INSTALL THE
_______ TRANSDUCER. IF THE WIRE HARNESS IS TWISTED, EQUIPMENT DAMAGE CAN OCCUR.
 (4)  
Connect the electrical connector to the transducer (12).

 S 424-014

 (5)  
Install the transducer assembly (4) in the support (2).

 NOTE: An alignment lug on the transducer aligns with a notch in
____
 the support (2)

 S 424-029
 (6)  
Install the retainer nut (7) as follows to hold the transducer assembly (4) in the support (2):

 (a)  
Tighten the retainer nut (7) to 40-60 pound-feet.

 (b)  
Then fully loosen the (7).

 (c)  
Tighten the nut (7) to 30 pound feet.

 (d)  
If lockwire holes in nut (7) and mating support housing (2) do not align, turn the nut until the lockwire holes align, but do not exceed 100 pound-feet torque.

 S 424-025
 (7)  
Install lockwire.

 S 424-015

 (8)  
Install the support (2) with the two axle nut bolts (3), the washers

 (6)
 and the nuts (5).

 S 214-016
 (9)  
Examine the transducer drive components in the hubcap to make sure that they are not damaged or loose. If the transducer drive components can be turned, replace them.

 S 714-017

 (10)
 Do a check to make sure that the transducer drive on the hubcap assembly will engage the antiskid transducer properly as follows:

 (a)  
Hold the hubcap assembly (1) in position against the transducer so that the transducer drive engages the dog on the transducer assembly (4).

 (b)  
Turn the transducer quickly with the hubcap to make sure that the transducer will rotate freely.

 (c)  
Do a visual check to make sure that the the transducer drive engages the dog on the transducer tightly.

 S 864-018
 (11)
 Remove the DO-NOT-CLOSE tags and close these circuit breakers on the P11 panel:

 (a)  
11C31, ANTI-SKID 2-6

 (b)  
11C32, ANTI-SKID 3-7

 (c)  
11S18, ANTI-SKID 1-5

 (d)  
11S22, ANTI-SKID 4-8

 (12)
 Supply electrical power (AMM 24-22-00/201).

 (13)
 Do a test of transducer operation.

 S 864-019
 S 714-020
 WARNING: MAKE SURE THAT THE AREA AROUND THE BRAKES IS CLEAR AND
_______ CHOCKS ARE INSTALLED ON THE WHEELS. THIS WILL PREVENT POSSIBLE DAMAGE TO EQUIPMENT OR INJURY TO PERSONS WHEN THE BRAKES APPLY AND RELEASE IN THIS TEST.
 (a)  
Pressurize the right hydraulic system and reservoir
 (AMM 29-11-00/201).

 (b)  
Release the parking brake.

 1) 6F4, LANDING GEAR PARKING BRAKE VLV
 (d)  Set the parking brake.
 NOTE: If you set the parking brake with the hydraulic____
 system pressurized you will not have to hold the brake
 pedals for the brake application test that follows.
 (e)  Turn the wheel speed transducers as quickly as possible
