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

shims. 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

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

stationary mast. Install 1 mm shim to each

bearing of stationary mast upper. Bearing should

be part number D581814 under size bearing.
