The carriage can have four or six load roll-
ers. When the carriage has four load rollers, shims
are used behind all of the load rollers. When the
carriage has six load rollers, shims are installed on

If any of the load rollers must be replaced,
make a note of the location and number of the
shims. Install the shims, load rollers, and snap
rings. See Carriage Adjustments for correct ad-
justment of the load rollers.
