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.
11.  Check the tightness of the front pivot balls.

Other periodic maintenance:

• 

Slipper clutch pad (friction material): 

 

Under normal use, the 
friction material in the 
slipper clutch should 
wear very slowly. If 
the slipper clutch fails 
to provide consistent 
performance or slips even 
when the adjustment nut is fully 
tightened, disassemble the slipper 
clutch and replace the slipper pad. Inspect 
the spur gear and pressure plate for wear or 
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 #7062.  

• 

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 the driveline for signs of wear such as worn 

drive yokes, dirty axle half shafts, and any unusual noise or 
binding. 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 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, then also remove the batteries from the transmitter.

Keep this manual and the other documents included with your 
model for future reference. If you misplace your manual or any of 
the documents, they may be downloaded at Traxxas.com.
