Changing The Motor Pinion - Reely BASH 6S Bedienungsanleitung

f) Changing the motor pinion
The vehicle is equipped with a motor pinion with 12 teeth.
Using the motor pinion with 12 teeth results in better acceleration, but lower end speed (up to approx. 90 km/h with
two 3-cell LiPo drive rechargeable batteries).
Important:
The high speed requires prompt responses when steering the vehicle. In addition, there must be enough
space for operating the vehicle, because the braking distance is significantly longer.
Proceed as follows:
• Turn off the speed controller and disconnect the two
drive rechargeable batteries from it.
• Loosen the three socket head screws (A) with a
suitable 3 mm hex key so that the motor bracket (B)
can be pulled out forwards a little bit, as shown by the
arrow in the right figure.
Do not fully unscrew the three screws, only
unscrew them far enough for the motor
bracket to be moved.
• Loosen the set screw (C) of the motor pinion (D) with
a 2 mm hex key (F), then pull the motor pinion off the
motor axle (note the orientation).
• Put the motor pinion with 14 teeth (H) on the motor axle
in the same orientation so that the flat side is facing
away from the motor.
• Apply a drop of thread-locking fluid to the set screw.
Then fix the motor pinion on the motor axle with the
set screw (G).
Make sure that the set screw is exactly on the flat side
of the motor drive axle and securely tightened there, as
shown in sketch (I).
Furthermore, make sure that the motor pinion rests
exactly on the drive gear and is not offset laterally, as
shown in sketch (J).
• Now adjust the backlash, as described in chapter 11.
g) below. It also details when and how to screw the
motor bracket.
