Required conditions
The tabletop rear cover is removed.
The left- and right-hand table side covers are removed.

About this task

Rigibelt teeth and the rigibelt plate are sharp. Wear gloves when handling the rigibelt drive.

CAUTION

Potential cut hazard

Sharp metal corners on the components can result in injury.

Wear gloves to avoid getting any cuts from sharp metal corners on the components.

Procedure

Move the table out of the scan room.
Loosen the two screws securing the rigibelt drive coupler.

Note: Push the Dock pedal if required to release and move the cradle to access the screws.

Figure 1. Rigibelt drive coupler screws
Push the coupler up off of the electromagnetic clutch shaft.

Note: Make sure the clutch shaft key remains installed in the clutch shaft.

Figure 2. Rigibelt drive coupler lift
Move the cradle off the tabletop surface until the two screws securing the rigibelt to the rigibelt mounting block are accessible in the cutout in the bottom of the tabletop.

Figure 3. Rigibelt mounting screws
Remove the two screws securing the rigibelt to the rigibelt mounting block.
Remove the two screws securing the rigibelt drive to the tabletop.

Figure 4. Rigibelt drive screws
Tilt the rear end of the rigibelt drive slightly, and move the rigibelt and coupler together towards the handle-end of the table until the coupler is past the motor.
