Adjusting The Backlash - Reely 1:10 Monster Truck électrique «Bad 1» 4WD RtR Notice D'emploi

d) Adjusting the backlash
The backlash is preset to an optimal setting and does not normally need to be corrected.
However, vibrations may cause the screws in the motor to become loose after prolonged use.
If this occurs, the screws must be tightened and you must check that the backlash is correct.
Remove the dust cover (A), which is located above the
gearbox. You will need to remove 2 clips (B) in order to
do this.
The distance between the main gear (C) and the engine
pinion (D) should be as small as possible whilst ensuring
that the gears are not too tight.
Loosen the upper screw (E) on the engine slightly. The
lower screw is difficult to access; it is not normally neces-
sary to loosen this screw.
Gently slide the engine with the engine pinion (D) in the
direction of the main gear (C).
The engine must not shake; the screws should
only be loosened enough to allow the engine to
move.
The engine pinion and the main gear should now grip each
other with no backlash. However, this is detrimental to the
lifespan of the gears.
Place a strip of thin paper (F) between the main gear (C)
and the engine pinion (D). Turn the main gear so that the
paper strip (max. 80 g!) is pulled between the two gears.
The pressure of the paper pushes the electric motor by the required amount.
Tighten the screws on the motor.
When you turn the main gear in the other direction to remove the strip of paper, both gears should be at the correct
distance to one another.
Ideally, the engine pinion should be as close as possible to the main gear whilst ensuring that the cogs do
not touch, as this makes the gears too tight.
If the gears (engine pinion and main gear) are too far apart, the cogs on the main gear will be damaged by
the engine pinion after just a few seconds, which will void the warranty/guarantee!
However, if the engine pinion presses against the main gear (i.e. there is no clearance between the cogs),
this will decrease performance, increase power consumption (the motor requires lots of power to turn the
main gear) and lead to premature wear.
