Remove the drive assembly from the platform.
The motor cable to the core will still be attached.
9.
Disconnect the motor cable at the drive assembly.
Installation
1.
Lift the new drive wheel up, compressing its springs, enough so that you can insert a 6-
dia. x 10 mm pin into the hole on the rear side of the assembly (there is a hole on each
side).
This will keep the springs compressed (the wheel will be in the up position), and make
installation easier.
If you saved a wheel pin when you uncrated the platform, you can use that. An M5 x
10 screw also works well for this. See Spring-Compression Hole (arrow) on page 143.
