MAINTAINING YOUR MODEL
Your model requires timely maintenance in order to stay in top
running condition. The following procedures should be taken
very seriously.
Inspect the vehicle for obvious damage or wear. Look for:
1. Cracked, bent, or damaged parts
2. Check the wheels and steering for binding.
3. Check the operation of the shock absorbers.
4. Check the wiring for any frayed wires or loose connections.
5. Check the mounting of the receiver and servo(s) and
speed control.
6. Check the tightness of the wheel nuts with a wrench.
7. Check the operation of the radio system, especially the
condition of the batteries.
8. Check for any loose screws in the chassis structure
or suspension.
9. Inspect the gears for wear, broken teeth, or debris lodged
between the teeth.
10. Check the tightness of the slipper clutch.
Other periodic maintenance:
• Slipper clutch pads (friction material):
Under normal use, the
friction material in the
slipper clutch should
wear very slowly. If the
thickness of any one of
the slipper clutch pads
is 0.35mm or less, the friction
disc should be replaced. Measure
the pad thickness using calipers.
• Chassis: Keep the chassis clean of accumulated dirt and grime.
Periodically inspect the chassis for damage.
• Motor: Every 10-15 runs, remove, clean, and lubricate the motor.
Use a product such as electric motor cleaning spray to flush dirt
out of the motor. After cleaning, lubricate the bushings at each
end of the motor with a drop of light-weight electric motor oil.
• Shocks: Keep the oil level in the shocks full. Use only 100%
pure silicone shock oil to prolong the life of the seals. If you are
experiencing leakage around the top of the shock, inspect the
o-ring in the top cap for signs of damage or distortion from
overtightening. If the bottom of the shock is leaking, then it
is time for a rebuild. The Traxxas rebuild kit for two shocks is
part #8262.
• Suspension: Periodically inspect the model for signs of damage,
such as bent rod ends, bent linkage rods, bent shock shafts, loose
screws, or any signs of stress or bending. Replace components as
needed.
• Driveline: Inspect the driveline for signs of wear such as worn,
dirty or corroded center drive shafts, dirty constant-velocity
driveshaft joints (center and front), and any unusual noise or
binding. Do not allow dirt and grime to collect in the drive cups.
After cleaning, lubricate the pins and cross pins with a drop of
light-weight machine oil. DO NOT use too much oil to avoid
build-up of dust and dirt. Remove the gear cover. Inspect the
spur gear for wear and check the tightness of the set screw in the
pinion gear. Tighten, clean, or replace components as needed.
Storage
When you are through running the model for the day, blow it off
with compressed air or use a soft bristled paint brush to dust-off
the vehicle. Always disconnect and remove the batteries from the
model whenever the model is stored. If the model will be stored for
a long time, then also remove the batteries from the transmitter.

lubricants.
