16. Engage the two ends of the replacement timing belt equally into the timing
belt clamp. Tighten the timing belt clamp screws sufficiently to allow belt
movement. Ensure the timing belt is straight between the two pulleys and
the timing belt clamp.
17. Fully tighten the timing belt clamp screws.
18. Manually position the timing belt clamp on the camera X axis timing belt so
that the distance X1 is equal to the distance X2.
19. Using a suitable cable tie, engage a forcemeter across the idle pulley. Apply
a horizontal force of 24kg to the belt. Maintaining this force, tighten the
locknut.
20. Remove the forcemeter. Do not remove the cable tie as further adjustment
may be necessary.
