Maintenance Guide; Adjusting Gear Mesh - XTM Racing X-Terminator 2e Operating Manual And Assembly Manual

Following a simple maintenance schedule will ensure that your X-Terminator 2e operates in top condition every time you use it. It is
strongly recommended.
Check the chassis for any loose screws, especially the motor pinion gear and the differential pinion output joint grub screws. Tighten
l
them if necessary.
Any screws that are threaded directly into metal should be secured in place with threadlock. This will prevent the screws from loosening
l
during use. Screws threaded into nylon or composite material do not require threadlock.
Do not overtighten any screws that thread into nylon or composite material or the material may strip out. Screws threaded into nylon
l
or composite material need only be tightened snugly.
Once in a while, remove the wheels and clean the wheel bearings, using a bearing cleaner. This will remove any dust and grit that
l
may, over time, damage the bearings. After cleaning the bearings, reoil them using a good quality bearing oil. Never run the bearings
dry or damage to the bearings will result.
Check the condition of your transmitter batteries each time you drive your X-Terminator 2e. If you think they might need replacement or
l
recharging, do so before driving your X-Terminator 2e again.
After a period of time the chassis will accumulate a lot of dirt and debris. This buildup should be cleaned off using a soft brush and
l
compressed air.
After cleaning the chassis and motor with compressed air, apply several drops of lubricating oil to the motor bearings to ensure top
l
performance.
Check that the wheel nuts are tight. Applying a small amount of threadlock will help prevent them from coming loose!
l
Check the suspension and steering system to ensure both are working smoothly without any binding.

n Adjusting Gear Mesh
When you change pinion gears, you must readjust the gear mesh to ensure proper operation. If the gear mesh is too loose, the gears
may strip out. If the gear mesh is set too tight, the gears will bind, causing damage to the gears and/or the motor.
The gear mesh should be set so that there is very slight play between the pinion gear and the spur gear. If you're using either of
the XTM Racing 12T, 13T, or 14T pinion gears, the gear mesh is set correctly based on the particular mounting holes you install
the motor into. If using other brand pinion gears, you may have to experiment with the mounting hole positions.
12T
After adjusting the position of the motor, you will need to pivot the motor heat-sink so that the top of the heat-sink is parallel with
the top of the motor mount. You can pivot the heat-sink by simply grasping it with your hand and twisting it. This will prevent the
heat-sink from interfering with the brake plate when reinstalled.
If you're using a pinion gear other than 12T, 13T or 14T, you can fine-tune the gear mesh by using two screws to hold the motor in
place instead of the standard four. Use one screw in the adjustment slot and a second screw in the centre hole directly opposite
the adjustment slot. You can then loosen both screws, pivot the motor to the desired position, then tighten the screws firmly. You will
need to reinstall the motor and motor mount assembly, then double-check the gear mesh. If it's not correct, remove the motor and motor
mount assembly, readjust the motor, then reinstall the assembly and check the gear mesh again. Repeat until you're satisfied that the
gear mesh is correct.

mAINTENANCE GUIDE

q Remove the two 3 x 10mm Flat Head screws that hold the ESC mounting plate in
place.
q Remove the two 4 x 10mm Flat Head screws and the two 4 x 15mm Flat Head screws
from the bottom of the chassis that hold the centre differential mounts in place.
q Push the differential assembly to the side, remove the rear centre dogbone, then
remove the motor and motor mount assembly from the centre differential.
q Remove the four 3 x 12mm Button Head screws that hold the motor to the motor
mount, then adjust the mounting position of the motor based on the size of the pinion
gear you're using. If you're using an XTM 12T pinion gear, rotate the motor to the left
one hole. If you're using an XTM 14T pinion gear, rotate the motor to the right one
13T
hole. When reinstalling the motor, make sure to apply threadlock to the four mounting
screws and tighten them firmly.
14T
q Reinstall the motor and motor mount assembly. Installation is the reverse of the
disassembly procedure.
