T-LOCK SERVO INSTALLATION
The TRX-6's T-Lock differential control servos are installed and pre-set
at the factory. If you need to remove the servos or the servo horns for
maintenance or cleaning, carefully note their orientation when you
reinstall them to make certain the T-Lock system operates properly.
Before reinstalling the spring-loaded servo horns, reset the servos'
output shafts to the "diffs open" position.
1. Switch the transmitter and receiver on and plug the T-Lock servos
into their correct positions on the receiver unit (see page 12).
2. Operate the transmitter's T-Lock switch to make certain both servos
operate properly, then place the switch in the "open" position for
unlocked front, intermediate, and rear diffs (see page 21).
3. Install the servo horns as shown below. Switch the transmitter and
on-board electronics off before completing the installation.
Front Differential T-Lock Servo
Differential Open: Install the spring-
loaded servo horn so the spring slot is
perpendicular to the linkage as shown.
Differential Locked: Switch the
transmitter and receiver on. Move the
T-Lock switch to the middle position
to lock the front differential. Confirm
that the servo's output shaft turns
counterclockwise to rotate the servo
horn to the position shown.
Intermediate and Rear Differentials
T-Lock Servo
Differentials Open: Install the spring-
loaded servo horn so the spring slot is
perpendicular to the linkage as shown.
Differentials Locked: Switch the
transmitter and receiver on. Move the
T-Lock switch to the forward-most
position to lock the intermediate and
rear differentials. Confirm that the servo's
output shaft turns counterclockwise to
rotate the servo horn to the position shown.
