Option Parts
Team Losi as well as other manufactures offer optional "hop-up" parts in two categories, performance and
appearance. When choosing appearance parts you must take into consideration the impact that these parts can
have on both performance and durability. As an example, chrome plated plastic wheels will have no effect on per-
formance but look cool. Aluminum wheels will look even cooler but will increase both rotating and unsprung mass,
which will greatly hinder performance. They will also increase the possibility of bending axles and breaking arms if
raced hard. Performance parts on the other hand replace existing parts and perform a function either differently or
better for a particular application like competition and racing. Choose wisely to achieve your goal. The option parts
you should consider that will offer the greatest boost to performance are:
Ball Bearings for the front wheels and rear hubs (B1100)
Oil filled shock absorbers
Rechargeable Ni-Cad pack
Ball differential (for racing)
Service/Repair
Radio/Speed Control & Motor, Chassis: If you have any problems other than those covered in the troubleshooting
section please call the electronics service dept. at +49/1805/472876. 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 layout the parts you remove to make it
easier to reassemble.
1) Unplug the motor. 2) Remove the gear cover (three screws). 3) 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 that attaches the
rear shock tower to the transmission and the 4 screws at the bottom of the
chassis that hold 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 re-installed 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 #A3066 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. Re-
assembly: 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 thru 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 re-install 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 that is 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 explained elsewhere. After you have changed the spur
gear you will have to adjust the slipper as described elsewhere.
