Maintaining Your Model - Traxxas 86086-4 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.
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 operation of the steering servos and ensure that
they are not binding.
11. Check the tightness of the pivot balls.
Other periodic maintenance:
• Cush Drive: The cush
drive system does not
require maintenance,
but should be inspected
periodically. If the Cush
Drive develops play
(spur gear movement that
does not also move the drive
shaft), disassemble the cush drive and
inspect the elastomer element (part #6465)
for damage and replace if necessary.
• Chassis: Keep the chassis clean of accumulated dirt and grime.
Periodically inspect the chassis for damage.
• 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 #5462.
• 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.
• Driveline: Inspect driveshafts to make sure the drive pins are not
cracked or extremely worn. Additional driveline noise can occur if
the driveline components are worn out. 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.
• Torque-biasing center drive unit: The E-Revo VXL Brushless is
equipped with a torque-biasing center drive unit. The drive unit
can be rebuilt, but it requires a detailed maintenance procedure
and the use of 20MM weight differential oil (part #5040).

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.
Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
