Changing A Tyre; Adjusting The Backlash - Reely 4WD RtR Notice D'emploi

c) Changing a tyre
The tyres are fixed on the wheel rim and cannot be removed. Therefore, if a tyre is worn, the entire wheel must be
replaced.
After removing the nut cover (A), loosen the wheel nut (B)
with a suitable socket wrench. Pull the wheel off the wheel
axle (D).
Attach the new wheel so that the hex socket on the inside
of the wheel rim fits exactly over the wheel hub nut (C).
Screw the wheel tight to the wheel axle with the wheel
nut (B) removed at the beginning. Do not apply any force
when tightening the wheel nut, otherwise the wheel will not
spin freely and the powertrain may be damaged. Insert the
nut cover (A) onto the wheel nut (B).
When you remove the rear wheel, the wheel
hub nut (C) may get stuck in the wheel rim or
become detached from the wheel axis (D). En-
sure that the drive pin (E) does not fall off.
If the wheel is subsequently re-fitted, it is important to check that the drive pin (E) is inserted exactly into the
centre of the wheel axle (D) and that it is positioned in the corresponding notch on the wheel hub nut (C).
If the drive pin (E) is missing, no torque can be transferred from the motor to the wheel and the wheel will
spin freely.
d) Adjusting the backlash
The manufacturer has already preset the backlash. As a rule, no correction is required.
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) by unscrewing the 3 screws.
The distance between the main gear (B) and the engine
pinion (C) should be as small as possible whilst ensuring
that the gears are not too tight.
Loosen the fixing screws (D) of the motor a little bit. Then
push the motor with the motor pinion (B) gently in the di-
rection of the main gear (C).
The engine must not shake; the screws should
only be loosened enough to allow the engine to
move.
