—If the spindle nose is slightly warm to the
touch, you have correct bearing preload.
—If the spindle nose is hotter than you
can comfortably keep your hand on, the
preload is too tight and you must repeat
the bearing preload adjustment procedure.
When repeating the procedure, rotate the
inner spanner nut a little less during
Step

Removing/Installing
Gap Insert
This lathe is equipped with a removable gap
insert that will allow for turning large diameter
workpieces. The gap was seated, pre-loaded,
and then ground for precise mating and alignment
at the factory. Removing the gap can cause the
lathe insert to slightly spring out of shape. When
re-installed, there is no guarantee that original
alignment and flush mating will be the same. For
this reason, removing the gap is considered a
permanent alteration to the lathe, even if it is later
re-installed.
