Gap Removal

the Model g0554z comes equipped with a gap
section below the spindle that can be removed for
turning large diameter parts or when using a large
diameter faceplate.
the gap is installed, then ground at the factory
during lathe assembly for precise fit and align-
ment. Factors during the remaining assembly
and subsequent transport of the machine apply
additional forces to the gap; therefore, replacing
the gap to the original position will be very difficult
once you remove it. if you choose to remove
the gap, we do not recommend attempting to
replace it.
Tools Needed
Wrench 14mm ................................................... 1
hex Wrench 8mm .............................................. 1
dead Blow hammer .......................................... 1
To remove the gap:
1.
Back up the preload set screw to release the
locking tension on the gap (see Figure 99).
