2.19.4 Replace the drive drum
Remove all screws used to fix the bearing blocks (14 to 24 screws, depending on
machine size). In case spacers were mounted between the bearing blocks and the
bottom plate, then they need to be re-used.
Disconnect the cable from the front media sensor.
Remove the drive drum while letting the spacers on the base plate.
Put the new drive drum in the machine while holding the bearing blocks with the flat
side up. In case spacers were used with the old drive drum, then they need to be used
with the new drive drum too.
Put all screws in place to hold the bearing blocks. Do not tighten the screws.
Hold the bearing block matching the first small sleeve next to the wide sleeve and
squeeze it together with its sleeve. Shift the bearing block and the sleeve left and
right to find the center of the workout in the baseplate. Push the bearing block to the
front of the machine. Fix the bearing block with the two screws.
