Section 9: Maintenance
Following a simple maintenance schedule will ensure that your truck, motor and radio system operate in top condition every time you
use them. It is strongly suggested.
●
Periodically check the gear mesh to make sure it is not out of
alignment. If necessary, reset the gear mesh before running the
truck again.
●
Check the chassis for any loose screws, nuts or bolts. Tighten
them if necessary.
●
Check the steering linkage for any signs of wear or misalign-
ment. Tighten and/or readjust it as necessary.
●
Once in a while, remove the wheels and clean the wheel bear-
ings using a bearing cleaner. This will remove any dust and grit
that may over time damage the bearings.
●
Check the electronics for any signs of damage. This should
include the steering servo, receiver, motor, wiring and electronic
speed control.
●
After a period of time the chassis will accumulate a lot of dirt
and debris. This build-up should be cleaned off using a stiff brush
and high-pressure air. Because the chassis is assembled from
molded nylon and plastic parts, use of chemical spray cleaners is
not recommended. These cleaners may damage the parts.
Replacement of parts damaged by chemical cleaners will not be
covered under warranty.
●
After cleaning the chassis you should oil the moving parts of
the chassis. Do not oil the slipper clutch or you will damage the
fiber disc and the slipper clutch will not work.
●
Periodically check the condition of the transmitter batteries.
If you think they might be low, replace them with a fresh set.
●
Periodically remove the motor from the truck and clean it
inside and out using a specially designed motor cleaner. Be
very careful not to get motor cleaner on the chassis.
●
After cleaning the motor with motor cleaner, always lightly
oil the motor bushings on each end of the motor.
●
Check the condition of the electrical connectors, including the
battery pack connector, for any signs of wear or damage.
●
Check the shocks to ensure they have not developed any leaks.
●
Check the body mounts and clips for loss of integrity.
●
Periodically check the tire/wheel joints. If a tire is coming
loose from the wheel, carefully glue it back down using a thin
bead of tire glue.
Section 8: Checking and Adjusting the Gear Mesh
It's important to periodically check the mesh between the motor pinion gear and the spur gear. Sometimes the motor can work itself
out of alignment during very rough running conditions.
To adjust the gear mesh, first remove the plastic gear cover.
Loosen the two screws that hold the motor in place and pivot the motor so there is a gap
between the pinion gear and the spur gear.
Slide a small piece of notebook paper or copier paper between the two gears. Pivot the
motor so that the pinion gear is pushed up against the spur gear and tighten the two screws.
Remove the paper and double-check the gear mesh. If the gear mesh is set properly, you should feel a very small amount of play
between the two gears. If there is an excessive amount of play or no play at all, readjust the gear mesh again.
WARNING
Do not run the truck if the gear mesh is out of alignment. Doing so can cause severe damage to the spur gear.
