bevel gears should be done at the same time
when the motor grease cups are refilled,
inasmuch as they can only be reached when
the motor has been withdrawn from the
sewing machine head).
(h) Replace the grease cups, being sure that
the wicks (GG, Fig. 30) enter the small
holes which lead to the armature shaft.
(i) Replace the motor in the machine.

machine, and it may be necessary to slightly
shift the motor to the left or right before
the final tightening of the screw (F, Fig. 27).
(k) Replace the motor cover.
To Lubricate the Bevel Gears
1. There are three sets of bevel gears in the
machine, as shown at (M, Fig. 32) and (N and 0,
Fig. 33). These bevel gears should be greased once
a year, preferably at the timie of greasing the motor.
2. The method of greasing the upper set of bevel
gears (M, Fig. 32), i.e., those which are located in
close proxiiriity to the motor itself, has been ex
plained under the heading ^^To Lubricate the Motor.
