ATTACHING GEARS
Attaching gears to the frame
When connecting gears onto the frame with a drive
axle, be sure to keep a proper gap (about 1 mm)
between the gears and the frames. Try to turn the
gear and confirm that every gear in the gear train
turns smoothly so that friction is minimized. This is
how you can achieve efficient power transmissions
(Fig. 4 & 5).

Holding gears in place
Axle locks are designed to
prevent a pulley wheel or
gear from moving along
the axle, or slipping. They
are easy to install without
removing the wheel or
axle (Fig. 6).
Lengthening drive axles
Use a small sprocket to connect two drive axles
together to lengthen when necessary (Fig. 7).

1. The anchor pin can be used to join rods
and frames (Fig. 1).
2. Frames can be connected directly to
each other end to end (Fig. 2).
3. You can use the end "A" of the part sep-
arator tool to pry an anchor pin out of a
hole (Fig. 3).
Arranging gear wheels symmetrically
When you use a motor to drive a wheeled vehicle,
the gear wheels should be arranged symmetrically
(the holes on the two opposite chain gear wheels
must be placed in a horizontal line parallel to the
axle) and be kept at the same driven speed, or the
motor will stall and the vehicle won't move (Fig. 8).
TIP! These
two holes
must be
placed in a
horizontal
line.

Meshing gears at 90°
When the two red gears mesh
with each other at 90°, the
one on the drive axle must be
assembled as close as pos-
sible to the outer end of the
axle so that a good mesh can
be ensured (Fig. 9).
Connecting chain links
Make sure that you attach the chain links together
with the smooth side always on the inside, so that
the transmission can run efficiently and smoothly
(Fig. 10). Note: Not all chain link colors shown are
included in this kit.
