SERVICE
The gap insert was installed, then ground flush
with the bed at the factory to ensure precise fit
and alignment. Therefore, if removed, it may
be difficult to re-install with the same degree
of alignment and mating when installed at the
factory.
Gap Removal &
Installation
2. Remove the two way-end cap screws, and
way set screws shown in Figure 161.
3. Tighten the two dowel pin jack nuts (Figure
161) until the pins are pulled free from the
gap insert.
4. Tap the outside of the gap insert with a dead
blow hammer to loosen, and remove it.
To re-install the gap insert:
1. Use mineral spirits and a clean lint-free rag
to clean the mating surfaces of the gap, bed,
and ways. If necessary, stone the mating
surfaces to remove scratches, dings, or burrs.
2. Wipe a thin layer of light machine oil on the
mating surfaces.
3. Place the gap insert into the bed and use a
block of wood or dead-blow hammer to align
it with the lathe bed.
4. Back off the dowel pin jack nuts, and tap the
dowel pins back into their respective holes
until seated. This will further help align the
gap insert and bed mating surfaces.
5. Install all fasteners (except the way set
screws) and lightly snug them in place.
6. Mount a base-mounted dial indicator to the
top of the saddle to indicate alignment. First
test the peak of the two prisms the saddle
rides on, then test the flanks of the prisms.
Jack the insert up or down by tightening or
loosening the gap bed cap screws.
7. Alternately tighten the fasteners and tap the
side of the gap insert into alignment.
8. Inspect the gap position 24 hours later to
make sure the gap is still aligned. Adjust
if necessary, then install the two way set
screws.

The gap insert (Figure 160), is a portion of the
lathe bed directly under the spindle that can be
removed to create additional space for turning
large diameter parts.
