Reassemble the mast in a sequence opposite to disassembly, observing the following conditions:
(1) Select proper end rollers to ensure that the gaps between the channel and end rollers can be assured
correctly: one between the outer mast end rollers and inner mast, one between inner mast end rollers
and outer mast, and carriage end rollers and inner mast.
(2) Install a three-piece set of shims (t = 1.0 mm [0.039 in.]) into each of the slipper holes at the top of the
outer mast.
(3) Install end rollers to the end roller shafts (outer and inner masts).
(4) Using a hoist crane, put the inner mast into the outer mast from below. Check the gap between the
outer mast channel and the side of the inner mast end roller. Measure the gaps at points A, B, and C of
theoutermastandadjust,ifnecessary,withshimssothattheybewithinthespeciedvalue.
(5) Using the same manner, adjust the gap between the inner mast channel and the side of the outer mast
end roller.
(6) Using a hoist, lift the carriage and reassemble it from the bottom end of the inner mast channel,
aligning with the end roller rails.
(7) Check the gaps between the side of each roller and the inner mast channel at three points (A1, B1, and
C1).
(8) The gap between each roller and the inner mast channel should be less than 0.5 mm [0.0197 in.].
Adjust, if necessary, with shims.
