Setting the Gear Mesh
1. Insert a small strip of common notebook paper between the pinion and spur gear by feeding it into the gears as
you slowly turn the spur gear with your fingers.
2. Lightly push the motor in toward the spur (if the motor will not move freely, loosen the top screw slightly) until the
pinion is resting solidly against the spur and tighten both mounting screws.
3. Remove the paper and test the mesh by holding your finger against the pinion while trying to rock the spur gear
back and forth. There should be a slight bit of movement before the motor is forced to turn over. If not, loosen the
motor screws slightly and push the motor away from the spur ever so slightly.
4. Retest the mesh and repeat with the other motor making sure all motor screws are tight when done.
5. Replace the gear cover or adjust the slipper if you have also changed the spur gear.
Radio Replacement/Service
If you have a radio problem, please call (877) 504-0233 for customer service. Most likely, unless 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 the truck and transmitter or the entire radio system, which would include the receiver/
speed control unit and steering servo. 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. The following is a complete guide to removing
the system.
Receiver/Speed Control (ESC)
Unplug the power lead, motor leads and steering servo. Do not attempt to open the receiver or electronic speed
control (ESC) as only a factory technician has the proper tools and parts to make any repairs necessary. The
receiver and ESC are mounted with double-sided foam tape. Use your thumb and index finger at the bottom of the
front corners to pull them from the mount. If this is difficult, ask for help. If necessary, carefully use a large flat-blade
screwdriver between the unit and the mount to pry it loose. Make sure you remove any leftover foam or adhesive
before remounting with common servo tape or hobby-type foam tape.
Cleaning
Performance can be hindered if dirt gets in any of the moving suspension parts. Use compressed air, a soft
paintbrush, or toothbrush to remove dust or dirt. Avoid using solvents or chemicals as they can actually wash dirt into
the bearings or moving parts as well as cause damage to the electronics.
