Maintainence
If you have any problems other than those covered in the troubleshooting section, please call the service department at
(877) 504-0233. They will be able to give your specific problem additional attention and instruct you as to what needs
to be done.
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.
Rebuilding the Differential
The gears in the differential will wear over time. The same is true for the outdrives, driveshafts, and rear axles. We
suggest using a small rag or paper towel to lay out the parts you remove to make it easier to reassemble.
Disassembly
1. Unplug the motor.
2. Remove the gear cover (three screws).
3. Remove the four screws on the bottom of the chassis.
4. Remove the screw attaching the rear bumper to the
transmission, the two screws securing the transmission
to the shock tower/keyed bracket, and the 2 screws
which attach the bumper to the rear skid plate.
5. Remove transmission from vehicle and disconnect
camber links from rear ball mount.
6. Remove screws attaching rear ball mount to
transmission.
7. Remove the left side of the gearbox by removing the
three screws.
8. Remove any shims on the bevel gears and set them
aside so they can be reinstalled in the same location.
9. Carefully remove the large plastic sun gear and
the bevel gears on either side of it. You can use
the removed differential assembly as a guide for
putting together the replacement unit (a little Losi
grease #LOSA3066 can be applied for even better
performance).
10. Remove the center mounted idler gear from the
gearbox. Remove the shaft and push out the ball
bearings from either side. Install these bearings in the
new gear.
Reassembly
Replace the idler gear and shaft into the center of the same right side of the gearbox. Replace any shims removed
from the right bevel gear and slide it through the lower bearing. Replace any shims that came off of the left side bevel
gear and allow it to slide through the lower bearing as you put the left gearbox half back into position. Replace the
screws and reinstall the rebuilt gearbox using the steps in reverse order that were used to remove it. Consult the
exploded view on Page 19 for more details.
Changing the Spur Gear
Remove the gear cover by removing the three small screws. If you are replacing the spur gear with one of a different
size (number of teeth), you must first loosen (do not remove) the two screws that secure the motor and slide it back
slightly. Remove the 3mm 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. If you have changed the
size of the spur, see Setting the Gear Mesh below. After you have changed the spur gear, you will have to adjust the
slipper as described elsewhere.
