Maintaining Your Model - Traxxas 68086-4 Owner's Manual

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 silicone
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. Inspect the spur gear for wear and check
the tightness of the set screws in the pinion gears. 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 battery from the model whenever the
model is stored. If the model will be stored for a long time, also remove the
batteries from the transmitter.
Suspension and slipper clutch assembly removal
The Slash 4X4 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 Slash 4x4 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 4x12 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.

Assembly
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.
The rear bulkhead (skid plate
under spur gear) has two
small holes in the bottom.
These are for drainage of this
area when running in very
wet conditions. To keep extra
dust/dirt out of the spur
gear, 3mm set screws can be
installed into these holes to
limit dirt entry. Use Traxxas
Part #2743 (sold separately).
