11. 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 stationary

mast. If intermediate mast is stuck and cannot

move by 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 stationary upper bearings. Repeat same

procedure of above until properly shimmed. There

is to be contact zero clearance (C) between

stationary 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. Lift 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.
