2. Make sure whether stationary mast upper bear-

ings are properly shimmed by rolling up and down

and moving intermediate mast to right and left. If

clearance between both masts can be detected,

pull out the intermediate mast from the stationary

mast with crane and add shim 0.5 mm or 1 mm to

both stationary upper bearings.

3. 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 do not

move rolling up and down, there might be exces-

sive shim. Pull out the intermediate mast from the

stationary mast and remove shim 0.5 mm to both

stationary upper bearings. Repeat same proce-

dure of aboves until properly shimmed. There is to

be contact zero clearance (C) between stationary

upper bearings and the widest point of intermedi-

ate 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.

1. 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 station-

ary 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.
