Replace 1. Prepare new clamp, by cleaning all faces with IPA wipes to ensure transport
grease has been removed. Particular attention should given to the piston
face.
2. Using a 1.5mm Allen key, remove the protective blanking screw from port B
and the venting screw from port A on the clamp.
3. Using a flat work surface and square block, set the mounting block edges
flush with the clamp edges. Secure the clamp to the mounting block using
a 2mm Allen key and cap head screws.
4. Repeat Steps 1 to 3 for the other clamp assembly.
5. Using a 5mm Allen key, remove the socket button head screws and shim
washers from the mid plate. Apply thread lock compound to the screws, and
refit loosely so the mid plate is free to move.

11. Use the isolator switch valve to reinstate the air supply to the APC modules.
12. Ensure that the zimmer clamps have energised. The mid plate assembly
should not be able to rise when manually lifting is attempted.
13. Using a 5mm Allen key, fully tighten the socket button head screws and shim
washers that attach the mid plate to the ball spline assemblies.
14. Use the isolator switch valve to isolate the air supply to the APC modules.
Disconnect the up-stream hose from the isolator switch to allow any residual
pressure in the system to vent. Reconnect the up-stream hose.
15. Ensure that the mid plate assembly has free movement. Lift the assembly
and allow to drop, checking that it drops under its own weight back to its
original position.
16. Install the top plate as detailed in Top Plate Replacement - Replace.
17. Install the board clamp foil as detailed in Board Clamp Foil Replacement -
Replace.
