Carriage or Reach Assembly Adjustments
Figure 19. Measuring Channel Width
ADJUST THRUST ROLLERS
1.
Measure the width between the outside edges of
the inner weldment in several places. See Fig-
ure 19. Make a note of the location and the value
of the maximum measurement.
2.
Measure and record the distance between the in-
side faces of the thrust rollers of the reach assem-
bly. See B of Figure 20.
Figure 20. Reach Assembly Side and Thrust
Roller Widths
3.
If the distance B is more than 4 mm (0.16 in.)
less than the maximum measurement of Step 1,
install smaller size thrust rollers. If the distance
B is more than 4 mm (0.16 in.) greater than
the maximum measurement of Step 1, install
larger size thrust rollers. Install the same size
rollers on each side for a minimum clearance
at the maximum measurement point (Step 1).
Thrust rollers have outside diameters of 74, 76,
or 78 mm (2.88, 2.96, or 3.04 in.).
