For use with LiteHawk ACE 4x4:

You can remove the Four Screws that hold the Motor Mount to the Chassis. These are very tight, they have been Thread Locked in place. I believe that they used a glue, but I would use a blue Loc-tite, when reinstalling.
To remove the Motor from the Mount, first loosen the Grub screw holding the Pinion gear to the Motor Shaft, and remove the Pinion Gear.
Then remove the two screws that hold it to the Mount, and lift away. Again, when reinstalling, use just a tiny drop of Blue Loc-tite on the screw, just be very careful that you don't get any inside the motor.
