Adjusting the Slipper
The slipper is a key component of the drivetrain that is designed to help absorb
sudden or large impacts that would otherwise stress various drivetrain parts. You
should never run the LST XXL 2 vehicle with the slipper locked (completely tight).
The slipper can also be used as a tuning aid for extremely slick conditions. To
easily adjust the slipper, remove the plug from the gear cover. Start by turning
the 1/4-inch adjustment nut clockwise (tighten) until it gets tight and the spring is
compressed. Do not overtighten as you will strip the nut. Now turn the adjustment
nut counterclockwise (loosen) one full turn. This should be a good overall setting.
2-Speed Adjustment
Although pre-adjusted at the factory, the two-speed can be adjusted to shift at the
point that suits you best. Under normal circumstances, it should shift slightly before
the engine reaches maximum power. The actual distance traveled will vary with
the gear ratio and tune of the engine. There are two adjustment screws (see fig 1)
that must be changed evenly for the two-speed to function correctly. Turning these
clockwise will make it shift later and require the engine to rev higher. Turning them
counterclockwise will make it shift earlier and require less engine speed. If you
should get lost adjusting the two-speed, start over at the factory setting by lightly
bottoming out the adjustment screws and then backing them out five full turns. The
procedure for adjusting the two-speed is as follows.
• Remove the gear cover.
• Turn the spur gears until the adjustment hole is visible in the bell housing between
the large and small spur gears.
• Hold the small spur gear and, using your thumb, rotate the slipper forward until
you can see the head of one of the adjustment screws.
• Use a 5/64 Allen wrench to make your adjustment in 1/2-turn increments. Use the
bent leg of the wrench as your guide.
• Turn the slipper forward 1/2 rotation to adjust the other adjustment screw like the
first.
(Remember to always adjust BOTH screws the same amount)
• Test drive the model to check the new shift point and replace the gear cover if
satisfied.
• Never run your model without the gear cover, as it is dangerous and gear damage
will occur!
