Mast Adjustment Lower Bearings
(A, B, C) Zero clearance. (D) Minimum clearance.
(3, 4, 5) Bearing. (6, 7, 8) Shims.
4. 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.
Carriage Adjustment
STD, FFL & FFT
NOTE: The standard, Full Free Lift and Full Free
Triple Lift carriage load bearings are all adjusted the
same way. The Full Free Triple Lift carriage is
shown in the following illustrations.
To make the carriage clearance adjustments,
carriage must be removed from the mast.
Use the procedure that follows to adjust carriage
load bearings.
Carriage Adjustment
(3) Upper Bearings. (4) Shims. (5) Bolt. (6) Screw.
(7) Middle Bearings. (8) Lower Bearings. (A) Zero Clearance.
(B) 6.0 to 9.0 mm. (.236 to .354 in) Clearance.
(C) Minimum Clearance.
1. Select lower bearings from the chart to obtain
minimum clearance (B) between bearings and
channel leg for full channel length. Use same
bearing in all six locations.
