Mechanical Drive for the Drum and BTR
The Drum Motor provides mechanical drive for the Drum and BTR. The Main Drive
Assembly transmits drive to the Drum. A shutter covers and protects the Drum surface.
When the Left Cover is closed, a mechanical link opens the Shutter. When the Left Cover
is open, the link closes the Shutter. A gear attached to the end of the Drum transmits
drive to the BTR. Since the BTR is attached to the Left Cover Assembly, the BTR is driven
only when the Left Cover is closed.
