maintaining your X-terminator 2 rtr nitro buggy
Following a simple maintenance schedule will ensure that your X-Terminator 2 RTR Nitro Buggy operates in top condition every time
you use it. It is strongly recommended.
●
Check the foam air filter element for dirt blockage. If the foam is dirty, remove it from the filter 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 filter oil.
●
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 threadlocker. This will prevent the screws from
loosening during use. Screws threaded into nylon or composite material do not require threadlocker.
●
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 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 your transmitter and receiver batteries after each time you drive your XT2. If you think they might need
replacement or recharging, do so before driving your XT2 again.
●
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
anodised and/or plated parts. Test on an inconspicuous area first.
●
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 gear, driveshafts (dogbones) 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
fuel's performance and will cause erratic engine operation.
●
After you have finished using your 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 and into the carburettor opening.
Pull the pull-start cord several times to distribute the oil throughout the engine, then reinstall the glow
plug and copper washer. This will prevent corrosion inside your engine.
●
Never leave unused fuel in the fuel tank for more than a couple of days. The nitromethane and methanol in the
fuel will evaporate, leaving the oil behind. This will eventually turn into a thick sludge that will require replacement
of the fuel tank to fix.
●
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, first start by setting 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 satisfied 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 firmly, 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 satisfied with the alignment, tighten the four screws on the
bottom of the chassis. With the wheels off the ground, you should be able to spin the clutch bell with
your finger. The clutch bell should rotate the spur gear and other drivetrain components rather easily. If
it's difficult 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.
