FINAL CHECKLIST
BEFORE RUNNING YOUR NEW TRIPLE-XT
for the first time, you should run down the following checklist — in order —
and complete the listed tasks. I'm sure you're anxious to get out and run your
new
Triple-XT
now that it's built, but following this simple checklist will help to make your first run with your new truck
much more enjoyable.
1.
Adjust the differential
See
About The Differential
in the tips section.
2.
Adjust the slipper
See
Adjusting The Slipper
in the tips section.
3.
Check for free suspension movement
All suspension arms should move freely. Any binds
will cause the truck to handle poorly. The steering
should also operate very freely.
4.
Set the rear ride height
The rear ride height should be set so that the dogbones
are level with the surface. See the
Rear Ride Height
section of the tips.
5.
Set the front ride height
The front ride height should be set so that the front
suspension arms are level with the surface. See the
Front Ride Height
section of the tips.
6.
Adjust the camber
The front camber should be set to about 1/2 degree
of negative camber (top of tire points in) at ride height.
Adjust the front camber with the tires turned straight
ahead. The rear camber should also be set to have
about 1/2 degree of negative camber at ride height.
See the
Camber
section of the tips.
7.
Set the front toe-in
Adjust the front tie rods so that, when the steering is
straight on the transmitter, the front tires are both
pointing straight. It is recommended that you start
with the front toe-in set to zero (no toe-in or toe-out).
8.
Charge a battery pack
Charge a battery pack as per battery manufacturer's
and/or charger manufacturer's instructions so that
radio adjustments can be made.
9.
Adjust the speed control
Following the manufacturer's instructions, adjust your
speed control, and set the throttle trim on your trans-
mitter so the the truck does not creep forward when
not applying throttle. Make sure that there is not too
much brake being applied when the trigger/stick is
in the neutral position.
10.
Set transmitter steering trim
The steering trim tab on the transmitter should be
adjusted so that the truck rolls straight when you are
not touching the steering wheel/stick. If the servo was
installed correctly, as per Tables 57A and 57B, the
wheels should turn equally to the left and right. If this
is not the case, refer to Table 57B and ensure that the
steering servo and rod were properly installed.
TIPS AND HINTS FROM THE TEAM
About The Differential
Never allow the diff to slip; that’s what the slipper is for. Before trying to adjust your diff, you need to
tighten the slipper until the spring is fully compressed. Next, hold the spur gear and right rear tire, then try turning the left rear tire
forward. It should be
very
difficult to turn the left rear tire. If the tire turns easily, the diff is too loose. To tighten the diff, line up
the slot in the diff screw with the groove in the left outdrive. Place the 1/16” Allen wrench through both of these slots. This will
lock the diff screw and the outdrive together. While holding the Allen wrench in place, turn the right rear tire forward about 1/8 of
a turn. Check the differential adjustment again and repeat the tightening process as necessary until the differential is no longer
slipping. The final differential adjustment check should be made by placing the truck on carpet, grass, or asphalt and punching the
throttle. The differential should not slip. If it does, tighten the diff in 1/8-turn increments as described above until the slippage stops.
Once the diff has been adjusted, it should still operate freely and feel smooth. If the diff screw starts to get tight before the diff
is close to being adjusted properly, the diff should be disassembled and inspected; you may have a problem with the differential
assembly. Refer to the assembly instructions to ensure that the diff is properly assembled and that all parts are properly seated in
the assembly.
There are a few things you should know about differentials. First, when rebuilding your diff, you should always
replace the small, 4-40 locknut. Second, after the diff has been built for a couple of hours, or been run a time or two, it
is not uncommon for the balls to seat into the rings and create a slightly loose adjustment. So, after your first run, check
the adjustment to avoid slippage. Third, remember: Never let the diff slip. Doing so can damage the diff balls, rings, and
gear. Always make sure that the slipper will slip before the diff.
