Following a simple maintenance schedule will ensure that your X-Terminator 2 RTR 4WD Nitro Buggy, XTM Racing 24.7 engine and radio
control system operate in top condition every time you use them. It is strongly recommended.
MAINTAINING YOUR X-TERMINATOR 2 RTR 4WD NITRO BUGGY
●
Check the foam air lter element for dirt blockage. If the foam is dirty, remove it from the lter housing and wash it in liquid soap and
warm water. Dry the foam element with a paper towel, reinstall it and "wet" it with air lter oil. See page # 11 for more info.
●
Check the chassis for any loose screws, especially the engine and the outdrive cup mounting screws. Tighten them if necessary.
●
Any screws that are threaded directly into metal should be secured into place with threadlock. This will prevent the screws from
loosening during use. Screws threaded into nylon or composite material do not require threadlock. Be sure not to use permanent
threadlock as this will prevent disassembly for maintenance or replacement of parts.
●
Check the steering linkage and the throttle/brake linkage for any signs of wear or misalignment. Tighten and/or
readjust them if necessary. Double-check that the grub screws in the steel collars are tight.
●
Once in a while, remove the wheels and clean the wheel bearings, using a bearing cleaner. This will remove any
dust and grit that 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.
● When you clean the wheel bearings as described above, also remove, clean and reoil the clutch bell bearings.
●
Check the fuel system, including the fuel tank and fuel tubing, for any signs of cracking or looseness. Replace any fuel tubing
you suspect may be damaged.
●
Check the condition of the transmitter and receiver batteries before and after you drive your X-Terminator 2 RTR 4WD Nitro Buggy.
If you think they might be low, replace them with a fresh set or recharge them as applicable.
●
After a period of time the chassis will accumulate a lot of dirt and debris, especially around the engine area. This buildup should be
cleaned off using a high-powered spray cleaner like Emerald Nitro Car Cleaner. Some nitro car cleaners will damage
●
After cleaning the chassis and engine with Nitro Car Cleaner, you should oil the moving parts of the chassis. Do not
oil the clutch bell, spur gears, drive shafts/dog bones or the brake discs.
●
Always use new fuel and keep the cap on the fuel tightly closed. As fuel ages it absorbs water, which
degrades the fuels performance and will cause erratic engine operation.
●
After you have nished using the engine for the day, remove the glow plug from the engine and
squirt several drops of high-quality after-run oil into the glow plug hole. Pull the pull-start cord
several times to distribute the oil throughout the engine, then reinstall the glow plug. This will
prevent corrosion inside the engine.
●
Never leave unused fuel in the fuel tank for more than a couple of days. The nitromethane and methanol
in the fuel will evapourate, leaving the oil behind. This will eventually turn into a thick sludge that will require
replacement of the fuel tank to x.
●
If you need to remove the engine to clean it or change the clutch bell, etc., it's important that you set the gear mesh between
the clutch bell and spur gear properly when reinstalling the engine; otherwise, the spur gear may be
damaged or the gears may bind. To set the gear mesh, rst start by having the engine mount assembly
temporarily in place, then slide the engine back within the mounts until the teeth on the clutch bell are
even with the spur gear. When satised with the alignment, tighten the four socket-cap screws to secure
the engine to the engine mounts. This will ensure that the clutch bell is lined up with the spur gear. Next,
place a piece of notebook paper between the clutch bell and the spur gear, and push the engine toward
the spur gear rmly, so that the notebook paper crinkles. When set properly, there should be very slight
play between the gears. If the gears are too tight they will bind and if they are too loose they will strip
out. When satised with the alignment, tighten the four hex screws on the bottom of the chassis. With
the wheels off the ground, you should be able to spin the clutch bell with your nger. The clutch bell
should rotate the spur gear and other drivetrain components rather easily. If it's difcult to rotate the
clutch bell, your gear mesh is likely too tight. Readjust the gear mesh, making sure to use a piece of notebook paper between the
gears. When set properly, the paper should be tightly crinkled, but not ripped or punctured.
