INTERMEDIATE U."'VER
SPRING TENSION (Figure
65A)*
With the printing bail in its extreme rear position, move the T lever
so
that its right end is in contact with the universal function lever extension
and
hold the reset lever so that its upper edge is horizontal.
Then hook
an
8
oz. scale
over the intermediate lever just above the spring arm
and
pull
horizontally
toward the
left of
the typing
unit.
It should
require
3/4
to
l-l/2 ozs. to
start
the lever .rooving.

PLATE ADJUSTJ£ENT
There should be
a barely
perceptible amount of backlash
between
the
motor pinion
and
th
e highest point
of the main
shaft gear.
The lateral align
ment of the
motor
pini
o
n
and
the
main
shaft gear should
be such that the center
line of the gear coincides with a vertical
line th
ro
ug
h
the
center
of th
e hole
in the motor pinion.
When printers are equip ped with motors not having elongated mounting
hole
a,
adj ust as follows:
(

)
Place the
typing unit on
a
n
adjusted ba se with motor assembly
and
tighten the three mounting thumb sc
rew
s
.
Facing the front of
t
he
base unit and with the keyboard
removed .from the
base, visua.J.ly check
the lateral alignment of
the motor pini on and the
main
shaft gear to
determine if a center line of the gear
coincides
with a
vertica l line
through the center of the hole in the motor
pinion.
If
these
lines
do not coincide, remove the �ping unit from the base unit and loosen
the four motor mounting screws.
Replace the typing unit on the base unit ani shift the motor by
taking up the pl� between the drilled motor mounti ng holes and the motor
mounting screws until the two lines previously mentioned coincide.
If there is
insufficient play in the motor mounting holes to permit the
mo
t
or
to be
shifted
sufficiently to cause the lines to coincide, shift the motor as much as possjb]s
in order to obtain the best possible lateraL alignment of the motor pinion
and
the main shaft gear.
See that the edges of the motor base are parallel to the
respective edges of th e motor plate.
Then remove the typing unit and tighten
the four motor mounting screws.
(2)
Loosen the rear motor plate mounting screw and the lock nut on the
motor plate adjusting screw.
Slightly loosen the two front rootor
plate mounting screws to prevent stripping of the threads while
making
the following adjustment:
Replace the typing unit and tighten the three mounting thumb screws.
By
means of the motor plate adjusting screw, a djust the vertic� position of
the motor pinion until there is a barely perceptible amount of backlash between
the motor pinion ani the highest point on the main shaft gear. This high point
