If you have any problems other than those covered in the troubleshooting section, please call the electronics service
department at (877) 504-02. They will be able to give your specific problem additional attention and instruct you as
to what needs to be done.
Chassis
If you have any questions other than those covered in the troubleshooting or maintenance sections, please call
(877) 504-02.
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).
. Remove the motor guard screws at the top of the transmission and the two at the
extreme rear bottom of the chassis.
4. Remove the screw attaching the rear shock tower to the transmission and the four
screws at the bottom of the chassis holding the gearbox in place and slide it out of the
chassis
5. Remove the left side of the gearbox by removing the three screws.
6. Remove any shims on the bevel gears and set them aside so they can be reinstalled in
the same location.
7. 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 Team Losi Teflon grease #LOSA066 can
be applied for even better performance).
8. 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 gear box half back into position. Replace
the screws and reinstall the rebuilt gearbox using the steps in reverse
order that were used to remove it.
Changing the Spur Gear
Remove the gear cover by removing the three small screws. If you are replacing the spur gear with one 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 mm 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 on the following page. After you have changed the spur gear, you will have to
adjust the slipper as described elsewhere.
