8. In case of standard and full free mast, inner lower

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 intermediate

lower bearings. Repeat same procedure of above

until properly shimmed. There is to be contact zero

clearance (C) between intermediate lower bearings

and stationary channel at approximately 475 mm

(18.7 in) channel lap.

B. Upper Bearing Adjustment of Stationary Mast

9. Lift by crane, and pull out intermediate mast from

stationary mast. Install 1 mm shim to each bearing

of stationary mast upper basically. Bearing should

be selected D581814 under size bearing.

Mast Adjustment Upper Bearings

(D) Zero clearance. (E) 0.80 mm (.031 in) Clearance maximum.

(F) Zero clearance. (7) Pads. (8) Shims. (9) Shims. (10) Shims.

10. Make sure stationary mast upper bearings 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.
