7. Remove the bottom cable harness. There is one screw at the top to remove. Hint: when you
reinstall the guide, make sure that the rear locking tab is seated in the sheet-metal chassis. (See
page 120 - 121 in the service manual). It may be necessary to disconnect the white door latch
from the front door. (Notice the red arrow call-out).
8. Remove the main drive assembly (MDA). There are six screws attaching the MDA to the chassis.
Carefully note the locations of the screws to be removed.
CAUTION: Removing the incorrect screws could lead to opening up the MDA, requiring a unit
replacement!
NOTE: Two gears may fall off, there are instructions in step 16 on how to align them during the
re-installation process.
