In case of standard and full free mast, stationary
upper bearings can be easily extruded by pulling
down the inner mast from the bottom of staionary
mast. If intermediate mast is stuck and do not
move rolling up and down, there might be
excessive shim. Pull out the intermediate mast
from the stationary mast and remove shim 0.5
mm to both staionary upper bearings. Repeat
same procedure of aboves until properly
shimmed. There is to be contact zero clearance
(C) between staionary upper bearings and the
widest point of intermediate mast to be checked
before.

(D) Zero clearance. (E) 0.80 mm (.031 in) Clearance maximum.
(F) Zero clearance. (7) Pads. (8) Shims. (9) Shims. (10) Shims.
12. Install shims (8) behind each pad (7) until there
is 0.80 mm (.031 in) maximum clearance (E)
between the pads and the inner and intermediate
masts with the masts at full extension. Lifting by
crane, and pull out intermediate mast from
stationary mast and insert the shims behind each
pad. In case of standard and full free mast, the
pads of stationary upper can be easily extruded
by pulling down the inner mast from the bottom
of stationary mast.
