FOLLOW THESE STEPS TO KEEP YOUR TRUCK IN SHAPE FOR RACING
FREQUENCY CRYSTALS
Every radio system comes with a set of
two frequency crystals. One is marked for
the transmitter (TX) and the other for the re-
ceiver (RX). They should be the same fre-
quency for both places. Your kit will come
with 27MHZ crystals. Some of these frequen-
cies are shown here.
If you run by yourself only, then you will
not have any frequency conflict problems. If
you run with someone else, then you must
make sure that you are on different frequen-
cies. If you and another person are both
of the batteries, the fuel tank, and the hoses
for leaks. Also check the firmness of mount-
ing of the receiver and servos, and check for
any frayed wires or loose connections.

using the same frequency, you can crash
each other’s trucks or cause it to go out of
control simply by turning on your radio while
his truck is running.
AIR FILTER
NEVER run your truck without the air
filter on. The air filter is essential for keep-
ing dirt out of the engine. The air filter should
be inspected carefully every time you refuel.
When the air filter starts to get dirty, do the
following steps:
1. Clean the foam out with fuel. Do this by
pouring a little fuel in a small can and knead-
CLEANING YOUR TRUCK
If your truck should get any dirt in the
moving or pivoting locations, it can reduce
handling or performance. The easiest way
to keep your gas truck clean is with a small
paint brush or toothbrush. This will help you
to get the dirt and mud out of the moving
locations.
Whenever your bushing and bearings are
not moving freely, spray them with electric
motor cleaner and lightly oil the bushings or
bearings with a lightweight electric motor oil.
It is good to do a visual inspection before
you start your truck every time.
DIFFERENTIAL MAINTENANCE
You should rebuild the differential when
the action gets somewhat “gritty” feeling. To
check, hold one rear wheel stationary while
turning the other one. It should feel smooth,
not gritty. Usually cleaning the diff parts
and applying new lube as in the instructions
will bring it back to new condition. The stan-
dard 3/32” carbide balls rarely need replac-
ing. Normally, as the parts seat, the diff will
get smoother. If the diff still feels gritty after
carefully cleaning and re-lubing the diff parts,
the thrust balls, thrust washers, and the drive
rings should be checked and possibly re-
placed. The parts will normally wear out in
the following order:
1. #6575 5/64” diff thrust balls (qty 6)
2. #6573 diff thrust washers (2)
3. #6579 diff drive rings (2)
Refer to the differential section to correctly
assemble the diff.
ing the filter in the fuel. When the foam looks
cleaner, then dispose of the fuel properly.
2. Dry the filter. Squeeze out the fuel with a
paper towel until it’s dry.
3. Apply Associated’s #7710 foam pre-filter
treatment to help keep the dirt out. Dab the
treatment all around the filter, put the filter
in a plastic bag and knead it until the filter is
saturated, but not soaked.
