Before lubricating the leadscrew and carriage
rack (see
Figure 130), clean them first with min-
eral spirits. Use a stiff brush to help remove any
debris or grime. Apply a thin coat of oil along the
entire length of the carriage rack. Use a stiff brush
to make sure oil is applied into the leadscrew
threads.
Note: In some environments, abrasive material
can become caught in the leadscrew lubricant and
drawn into the half nut. In this case, lubricate the
leadscrew with a quality dry lubricant.

Use the handwheels to separately move the
cross slide and compound rest as far forward as
possible (see
Figure 132). Clean the slides with
mineral spirits and wipe down with a rag. Apply
lubricant and move the slides back and forth to
distribute the oil.

The gearbox can be quickly lubricated (as
necessary or if noisy) by removing the set screw
shown in
Figure 109 and adding a shot or two of
grease from a grease gun. The grease inside the
gearbox will eventually need to be replaced. To do
this, remove the gearbox cover, use mineral spirits
and a stiff brush to clean gears, allow them to dry,
reapply new grease, and re-install cover.
