D) Adjusting The Backlash - Reely Generation X 3S Bedienungsanleitung

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 8 screws in order to do
this.
The distance between the main gear (B) and the motor
pinion (C) should be as small as possible whilst ensuring
that the gears are not too tight.
Loosen the screws (D) on the motor slightly, and then gen-
tly slide the motor with the motor pinion (C) towards the
main gear (B).
The motor must not shake; the screws should
only be loosened enough to allow the motor to
move.
The motor 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 (E) between the main gear (B)
and the motor pinion (C). 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 (D) on the motor.
When you turn the main gear in the other direction to re-
move the strip of paper, both gears should be at the cor-
rect distance to one another.
Ideally, the motor 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 (motor pinion and main gear) are too far apart, the cogs on the main gear will be damaged by
the motor pinion after just a few seconds, which will void the warranty/guarantee!
However, if the motor 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.
