Changing the Spur Gear
Remove the gear cover by removing the three small screws. Remove the slipper adjustment
nut at the end of the slipper shaft and all of the slipper parts on the outside of the spur gear as
well as the old gear. Place the new spur gear into position and replace the slipper parts. After
you have changed the spur gear, you will have to adjust the slipper as described in the “Slipper
Adjusment” section on page 3.
Changing the Pinion Gear/Gear Ratio
Before you change the pinion, ask yourself why you are doing it. In general, if you change to a
larger pinion the top speed will improve, but you will see less acceleration and run time. This
would only be advisable for really long track layouts with few tight turns. Changing to a smaller
pinion will give you quicker acceleration and possibly a bit longer run time but a little less top
speed. This would be good for short layouts or when running faster motors. The pinion that is
on the Micro-DT offers the best balance of both. To change the pinion, remove the gear cover,
loosen the motor screws and slide the motor back. Use a small flat head screwdriver between
the motor plate and pinion gear to push the gear off. Place the new pinion on the end of the mo-
tor shaft and press the new pinion gear into the same position as the one removed.
chassis. 5) Remove the left side of the gearbox by removing the three screws. 6) Follow Figure
1 below to rebuild the differential (Use LOSA3066 Grease). 7) Once the differential has been
rebuilt, assemble the transmission by following the steps in the reverse order. Be sure to use the
screws in the same location that they were removed.
Setting the Gear Mesh
The motor screws should be slightly loose. Slide the motor forward al-
lowing the pinion gear to mesh with the spur gear. Snug (not tighten) the
bottom motor screw and try rocking the spur back and forth. There shoud
be a slight bit of movement before the motor is forced to turn over. If not,
pull the top of the motor back slightly and recheck. If there is too much slop
between the gears, push the top of the motor forward. When set properly,
the wheels can be spun forward freely with very little noise. Make sure to
tighten both motor screws and replace the gear cover before running.
Radio Replacement/Service
If you have a radio problem please call 1-877-504-0233 for customer service. Most likely, un-
less you have gotten the components wet, the service technician can help you fix the problem
over the phone. If the problem is more severe, you may be asked to send in your vehicle and
transmitter. In some cases, like a broken servo or a speed control that has failed due to getting
wet, your local dealer can sell you the replacement component.
