Make sure inner mast lower bearings are
properly shimmed in the intermediate mast by
rolling up and down and moving inner mast to
right and left. If clearance between both masts
can be detected, pull down the inner mast from
the bottom of inter-mediate mast. Inner lower
bearings can be easily extruded. Add shim 0.5
mm or 1 mm to both inner lower bearings. If inner
mast is stuck and cannot move by rolling up and
down, there might be excessive shim. Pull out
the inner mast from the intermediate mast and
remove shim 0.5 mm to both inner lower
bearings. Repeat same procedure of above until
properly shimmed. There is to be contact zero
clearance (C) between inner lower bearing sand
intermediate channel at narrowest point.
E. Upper Bearing Adjustment of intermediate
Mast
Follow same procedure with above B.
F. Upper Pad Adjustment of Intermediate Mast
Follow same procedure with above C.
17.
If the bearings (13) were removed from the mast
mounting blocks, install new ones.
18.
Put a small amount of clean grease on mounting
bores (11).

If the bearings (12) were removed from the tilt
cylinder pin bores, install new ones.
