Set the vehicle on a flat surface and turn the threaded collars on the shocks evenly so both the front and rear suspension arms are level.
PRecAutiOns
• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
geARing
Your vehicle has been equipped with the optimal gearing for the stock platform.
It offers an ideal balance between speed, power and efficiency. Should you
decide to customize your vehicle with optional batteries or motors, it may be
necessary for you to change the pinion or spur gear.
Installing a pinion gear with fewer teeth or a spur gear with more teeth will pro-
vide greater torque but will reduce top speed. Likewise, a pinion gear with more
teeth or a spur gear with fewer teeth will reduce torque and increase top speed.
Care should be taken when installing larger pinion gears as this can “overgear”
the vehicle, resulting in overheating of the motor and ESC. When testing differ-
ent gearing options, pay close attention to the temperature of the motor and
speed control to ensure you are operating within the temperature range of the
components. The motor or ESC should never be so hot that it cannot be touched.
If temperatures are too hot, a different gearing combination with a lower pinion
gear and/or higher spur gear is suggested.
chAnging the PiniOn geAR/geAR RAtiO
1. Unscrew the gear cover screw and remove the gear cover.
2. Loosen the motor screws and slide the motor over.
3. Place the new pinion on the end of the motor shaft so the set screw is
located over the flat on the shaft.
4. Position it so the teeth line up with the spur gear and secure the pinion by
tightening the set screw.
5. Set the gear mesh.
6. Reinstall the gear cover.
setting the geAR mesh
The gear mesh has already been set at the factory. Setting it is only necessary
when changing motors or gears.
Proper gear mesh (how gear teeth meet) is important to the performance of the
vehicle. When the gear mesh is too loose, the spur gear could be damaged by
the pinion gear of the motor. If the mesh is too tight, speed could be limited and
the motor and ESC will overheat.
1. Unscrew the gear cover screw and remove the gear cover.
2. Loosen the motor screws and slide the motor over.
tiP:
The bottom motor screw can be accessed from the bottom of the vehicle.
3. Put a small piece of paper between the pinion and spur gears.
4. Push the gears together while tightening the motor screws.
5. Remove the paper. Check the mesh at 3–5 different locations around the
spur gear for a small amount of movement.
6. Reinstall the gear cover.
tiP:
Stock gearing for the vehicle is 50/13. Optional 11t, 12t and 14t pinion
gears are available.
