5. 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 outer intermediate mast is stuck and cannot
move by rolling up and down, there might be
excessive shims. Pull out the outer
intermediate mast from the stationary mast and
remove shim 0.5 mm to both outer 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.
