Operation
Motor Precautions
• The 550 motor’s 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.
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 and rear differential:
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 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.
•
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.
