Removal
1.
Remove the inner rear cover.
2.
Unlatch and open the battery compartment door, at the back of the platform.
The battery compartment door is capable of being locked. You may need to unlock it before
opening.
3.
Disconnect battery power by unplugging the two cables at the rear of the battery.
4.
Remove the side cover a small distance from the platform on the side where you want to replace
the drive assembly. Refer to Removing and Installing Covers on page 93.
The light disc PCA cable will still be attached.
5.
Disconnect the cable from the light disc PCA, so the side cover can be moved completely away
from the platform.
This will expose the drive assembly.
6.
Lift the drive wheel up, compressing its springs, enough so that you can insert a Ø6 x 10
mm (Ø0.24 x 0.4 in.) 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 removal
easier. An M5 x 10 screw works well for this.
7.
The drive assembly is held in place with three nuts on studs across the top, and two sets of two
screws at each side, near the bottom of the assembly.
Remove the three nuts and four screws (and their washers) holding the drive assembly to the
platform.
Retain these nuts, screws, and washers for attaching the new drive assembly.
