C-Arm Components—Remove and Replace
3.3 Compression Assembly
This section details the removal and replacement procedures for the components that make
up the Compression Assembly. The alignment, adjustment and/or calibration procedures are
provided as required.
3.3.1 Compression Device Covers
Access to the serviceable components and assemblies of the C-arm are through
these covers:
• Upper Compression Device Cover
• Lower Compression Device Cover
Note… The top and bottom Compression Device covers are fastened to the
compression bellows. Use care not to damage the bellows when removing
these covers.
1. Remove the mounting hardware that fastens the Compression Device covers
(top and bottom) to the Compression Device. (See Figure 6-17.)
2. Carefully lift the covers off the Compression Device to access the following
components:
• Compression Clutch
• Compression Clutch brake
• Compression Drive
• Compression Brake
• Compression Tray Sensor Board
• Compression Force and Thickness Boards
3. Disconnect the wiring between the covers and the Compression Device,
including 1 ground wire for each cover.
4. Reverse procedures to replace the Compression Device Covers.
3.3.2 Compression Motor & Brake Assembly
The Compression Motor assembly is mounted on a rail inside the C-arm frame (near
the bottom). Access to this assembly requires removal of the C-arm covers.
1. Turn power OFF. Remove the C-arm top and bottom covers (as per Section
3.1.2, Steps 2 and 3) and the upper & lower Compression Device covers (as per
Section 3.3.1). Use care not to damage the compression device bellows.
2. Raise the compression device completely using the manual handwheels.
3. Continue to turn the handwheels to rotate the compression motor sprocket until
the cam-lock set screw (on the compression motor sprocket) is accessible.
Loosen the set screw 1/2-turn.
Note… The cam-lock set screw is recessed further in the compression motor
sprocket than the key-way set screw, which is flush when tight.
4. Turn the handwheel again to continue rotating the motor sprocket to access the
key-way set screws. Loosen this set screw 1/2-turn.
