Dismantling
To remove the unit, remove the two #T20 Torx screws that hold the
fl ange from inside the electronics compartment and pull the belt
off the gear wheel. Then dismantle the gear wheel by removing the
snap ring. Now you can pull the remaining parts of the unit out into
the media compartment.
To dismantle the unit further, remove the #T20 Torx screw and
washer at the end of the shaft and pull off the bobbin, the compres-
sion spring, and the nylon washer. Then you can inspect the fric-
tion felt. No further dismantling is normally required.
Reassemble in reverse order, making sure that the one-way clutch
in the gear wheel works in the correct direction. Finally, fi t the belt
over the gear wheel, adjust the tension of the belt as described in
Chapter 8.5, and tighten the screws that hold the fl ange.
