Step 6
Assemble the treads from the
Track and Wheel Set using the
following lengths for each tread
(for an overall length of
approximately 14 1/2"):
1 7 1/2"
1 2"
2 2 1/2"
Temporarily mount one
completed tread to the left rail as
follows:
1. Push the servo as far toward
the front of its mounting slots
as possible.
2. Loop the tread over the four
idler wheels.
3. Wrap the tread around the
teeth of the drive sprocket,
and carefully push the
sprocket onto the servo
motor shaft.
4. Pull the servo back in its
mounting slots to exert
medium tension on the tread.
The tread should be springy,
but not overly tight.
Note: Do not overstretch the
tread or it may become unlinked.
If desired, at this time you may
attach the other two sets of
machine screws, nuts, and
washers to the servo motor.
For ease of construction,
remove the drive sprocket and
track when the above steps are
done. The servos do not need to
be loosened. Simply remove the
sprocket from the servo motor
shaft.
