Mast Adjustment Lower Bearings
(A, B, C) Zero clearance. (D) Minimum clearance.
(3, 4, 5) Bearing (6, 7, 8) Shims.
16. 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
intermediate 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 inner 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 bearings and inner intermediate channel at
narrowest point.
F. Upper Bearing Adjustment of Inner Intermediate
Mast
Follow same procedure with above B.
G. Upper Pad Adjustment of Inner Intermediate
Mast
Follow same procedure with above C.
17. If the bearings were removed from the mast
mounting blocks, install new ones.
18. Put a small amount of clean grease on mounting
pins (11). Install mounting pins (11) into mast
mounting blocks.
19. If the bearings were removed from the tilt cylinder
pin bores, install new ones.
