MAINTAINING YOUR MODEL
Your model requires timely maintenance in order to stay in top running
condition.
The following procedures should be taken very seriously.
Frequently 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. Check the operation of the steering servo and ensure that it is not binding.
10. Inspect the gears for wear, broken teeth, or debris lodged between the teeth.
11. 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 1.8mm or
less, the friction disc should be replaced. Measure
the pad thickness using calipers or measuring against the
diameter of the 1.5 and 2.0mm hex wrenches provided with the model.
•
Chassis
: Keep the chassis clean of accumulated dirt and grime.
Periodically inspect the chassis for damage.
•
Suspension
: Periodically inspect the model for signs of damage such as
bent or dirty suspension pins, bent turnbuckles, loose screws, and any
signs of stress or bending. Replace components as needed.
•
Steering
: Over time, you may notice increased looseness in the steering
system. The tie rod ends may wear out from use (Traxxas Parts #2742 and
#5525). Replace these components as needed to restore factory tolerances.
•
Shocks
: Keep the oil level in the shocks full. Use only 100% pure silicon
shock oil to prolong the life of the seals. If you are experiencing
leakage around the top of the shock, inspect the bladder 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 #2362.
•
Driveline
: Inspect the driveline for signs of wear such as worn
drive yokes, dirty axle half shafts, and any unusual noise or
binding. If a U-joint pops apart then it is time to replace the
part. Remove the gear cover and Inspect the spur gear for
wear and check the tightness of set screws in the pinion gears.
Tighten, clean, or replace components as needed.
Storage
When you are through running your 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 battery from your model whenever
the model is stored. If your model will be stored for a long time, then also
remove the batteries from the transmitter.
Suspension and slipper clutch assembly removal
Your model was designed with ease of disassembly in mind. The entire front
and rear suspension assemblies can be removed from the chassis fully intact
with the removal of only a few screws. Refer to the exploded views included in
the Service Support Guide for complete assembly diagrams.
Removing the front suspension module
1. Remove the two 4x12 button-head cap screws from the front of the chassis.
2. Remove the two 4x10 button-head cap screws from the top of the chassis.
3. Remove the 3x15 button-head cap screw from the steering link under the chassis.
4. Pull the front suspension assembly away from the chassis.
Removing the rear suspension module (Slipper clutch assembly removal)
1. Remove the two 4x12 button-head cap screws from the top of the chassis.
2. Remove the two 4x14 button-head cap screws from the bottom of the chassis.
3. Pull the rear suspension assembly away from the chassis.
4. The slipper clutch assembly can now be removed.
Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
High performance vehicles
generate small vibrations
while driving. These
vibrations may loosen
hardware over time and
require attention. Always
check your wheel nuts and
other hardware and tighten
or replace when necessary.
