Gearing
Improper gearing will cause excessive heat
buildup in the motor and speed control. Use
your vehicle’s kit manual in order to find the
manufacturer’s recommended pinion size. It is
best to monitor the motor’s operating temperature
when you are operating on new and different
tracks or racing surfaces, changing to a new
motor or making gearing changes. Your motor’s
operating temperature should never exceed 160°
F (71° C). The best place to monitor the motor’s
temperature is at the center of the end bell. If the
motor temperature is higher than 160° F (71°
C) after a 5 minute run, the gearing should be
lowered (change to a smaller pinion gear).
CAUTION:
Once the battery is connected
to the motor, stay clear of the rotating shaft and
pinion gear. Failure to do so could result in
personal injury.
Installation of the Motor
Always make sure the motor mounting screws
are long enough to properly seat into the motor.
However, ensure the screws do not enter into the
motor too far, which could damage the motor.
The maximum depth that the motor mounting
screws can enter into the motor is approximately
1/8 in (3mm). We suggest using the motor
mounting hardware included with your vehicle.
The use of screws that are too long will damage
the motor and void any warranty.
When installing the motor into your vehicle, it
is very important that the gear mesh is correct
and smooth with no binding. The vehicle’s
motor mounts usually feature adjustable slotted
mounting holes so that you can adjust the gear
mesh properly.
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. Insert a small piece
of paper in between the pinion and spur gears as
you are installing them. Push the gears together
while tightening the screws that mount the motor.
When the mesh is at the correct distance, remove
the small piece of paper by rotating the spur gear
until the paper comes out. Check the mesh at
multiple points around the larger spur gear before
finalizing the motor mounting position.
