CAUTION
The motor weighs 38 kg! All lifting equipment
used must be sized accordingly!
Lift the motor and guide it onto the guide pins,
as close to the correct position as possible
without pushing the motor pinion into the
gear.
Make sure that the motor is turned the right
direction, that is the cables facing .
Use the rotation tool in order to rotate the
motor pinion when mating it to the gear (see

sure the motor pinion is properly mated to
the gear of gearbox axis 2 and that it does
not get damaged.
Remove the guide pins.
