Motor Precautions
• Titan 550 motor life can be greatly reduced in mud and water. If the
motor gets excessively wet or submerged, use very light throttle (run
the motor slowly) until the excess water can run out. Applying full
throttle to a motor full of water can cause rapid motor failure. Your
driving habits will determine motor life with a wet motor. Do not
submerge the motor under water.
• Do not gear the motor by temperature when running in wet
conditions. The motor will be cooled by water contact and will not
give an accurate indication of appropriate gearing.
After Running Your Vehicle in Wet Conditions
1. Remove the batteries.
2. Rinse excess dirt and mud off the truck with low-pressure water, such
as from a garden hose. Do not use a pressure washer or other high-
pressure water. Avoid directing water into the bearings, transmission,
differentials, etc.
3. Blow off the truck with compressed air (optional, but recommended).
Wear safety glasses when using compressed air.
4. Remove the wheels from the truck.
5. Spray all the bearings, drivetrain, and fasteners with WD-40® or
similar water-displacing light oil.
6. Let the truck stand or you may blow off with compressed air. Placing
the truck in a warm, sunny spot will aid drying. Trapped water and oil
will continue to drip from the truck for a few hours. Place it on a towel
or piece of cardboard to protect the surface underneath.
7. As a precautionary step, remove the sealed receiver box cover. While
unlikely, humidity or tiny amounts of moisture or condensation may
enter the receiver box during wet running. This can cause long-term
problems with the sensitive electronics in the receiver. Removing
the receiver box cover during storage allows the air inside to dry. This
step can improve the long-term reliability of the receiver. It is not
necessary to remove the receiver or unplug any of the wires.
8. Additional Maintenance: Increase your frequency of disassembly,
inspection, and lubrication of the following items. This is necessary
after extended wet use or if the vehicle will not be used for an
extended period of time (such as a week or longer). This additional
maintenance is needed to prevent any trapped moisture from
corroding internal steel components.
• Portal gearboxes: Open, dry, clean, and re-grease the
gears and inspect for damage.
• Front, intermediate, and rear differentials: Remove the
differential covers to disassemble, clean, and re-grease
the ring and pinion gears. Refer to your exploded view
diagrams for help with disassembly and reassembly.
• Transmission: Remove, disassemble, clean, and
re-grease the transmission components. Use a light
coating of high-performance grease (such as Traxxas
part #5041) on the metal gear teeth. No grease is required for the
nylon gears. Refer to your exploded view diagrams for help with
disassembly and reassembly.
• Titan 550 motor: Remove the motor, clean with aerosol motor
cleaner, and re-oil the bushings with lightweight motor oil. Be sure
to wear eye protection when using spray aerosol cleaners.
