lubrication
points requiring periodic lubrication are:
•
the main column. A light film of oil (sAe
30) will smooth action and prevent rust and
corrosion.
•
the quill. A light coating of oil (sAe 30) will
ensure smooth movement.
•
the quill pinion. lubricate every 90 days
with non-hardening grease.
•
the table leadscrews. lubricate once each
week with several drops of sAe 30.
•
ball oilers. Wipe the outer surface of the
ball fitting with a clean cloth to remove con-
taminants. press the ball of the fitting with
the tip of the oiler. press a few drops of oil
into the ball fitting, then clean up any residue
with a cloth (figure 39).
Ways. periodically lubricate the ways with
•
Moly-d way oil.

v-belts
inspect regularly for tension and wear. refer to
figure 40 for proper belt tension. Belt deflection
should be approximately 1/4" under moderate
pressure. replace when necessary with a size
B-42 belt for the spindle pulley to the idler pulley
belt and a size B-34 belt from the idler pulley to
the motor pulley belt. Check pulleys to ensure that
they are properly aligned.
