A-9.
Brush holders (18) occasionally become loose because of shrinkage due to heat
from the motor under prolonged use. To tighten or replace brush holders, set
screws (22) which keep the holders in place can be adjusted. With a long thin
screw driver inserted in the same screw hole through which baffle p1ate
retaining screws (23) enter.
A-l0. To remove front motor cover (7) and Bakelite motor handle (78), first push
Bakelite handle down into position along the side of the motor, then unscrew
grille and front motor cover retaining screw (114). Pull out the front cover.
The Bakelite handle may now be separated from the front cover by turning out
the two handle screws (73) and split lock washers (80) which hold the cover
and handle together.
A-11. Take off gear case cover (121) by turning out the four gear case cover screws
(108). Be careful with gear case cover gasket (6).
A-12. To remove whipper spindle sleeves (13 and 20) and worm gears (9) if the
armature is in the motor, put both whippers n the sleeves and rotate whippers
inward until worm gears set screws (10) are facing the workman. Then take the
setscrews out of the worm gears with wrench T16023 and pull whipper spindle
sleeves down and out of the gear case. Next remove the worm gears.

Assembling the Motor
B-1.
If brush holders (18) have been removed, put them back in the motor housing,
being careful to see that the broached flats on the inside lie parallel with
armature shaft. Tighten brush holders in place with set screws (22), using
thin screwdriver as described in Section A-9.
B-2. If front of motor is not assembled; that is, if whipper spindle sleeves (13
and 20) and worm gears (9) are not in gear case, put armature assembly into
motor housing from the rear - commutator end first - being careful not to bend
the two vanes of the centrifugal brake (27A), which is fitted around the
armature shaft next to the commutator. The worm end of the armature shaft must
be pushed all the way through the front bearing hole and into the gear
housing. Be sure to have brushes out of the motor when fitting armature into
p1ace.
B-2a. If the parts in the front of the motor have not been taken out (the whipper
spindle sleeves, worm gears, etc.), the armature assembly may be fitted into
the motor housing without removing parts in front if the following precautions
are taken to assure proper position of whipper spindle sleeves (see Section A
-7). Put the two whippers into the spindle sleeves and turn each so that the
blades of either whipper clear, with maximum distance the blades of the other
whipper. Then push armature all the way in, and again check relative position
of whippers. If the whippers are not in best relative position to avoid
striking of blades, pull out armature, revolve one whipper a fraction of a
turn in the direction necessary to correct the adjustment and put armature
back in again.
B-3. Rep1ace baffle plate (132), being careful to line up keyways. Put in
