Loosen locking screws gradually in a cross sequence, shown in Figure 10
47.

4.
Release front collar by progressively tightening all push-off screws.
Typically, the push-off screws appear to be completely tight after just one pass of tightening
without any noticeable separation of clamp collars. Although it seems that the screws cannot be
tightened further, several more rounds of torqueing in a cross sequence will increase the push-off
force in the system and ultimately release the front collar.
5.
To release the rear collar, continue tightening the screws in the front collar.
