Mast Adjustment Lower Bearings
(A) Zero clearance. (B) Minimum clearance. (C) Zero clearance.
(3) Bearing. (4) Bearing. (5) Shims. (6) Shims.
4. Make sure whether 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 do not move 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 proce-
dure of aboves until properly shimmed. There is to
be contact zero clearance (C) between inner lower
bearings and 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.
Carriage Adjustment
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, car-
riage 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.
