4. Remove rear bearing retainer plate.
5. Loosen side joggler cam, clutch hub (with
grease fitting), and clutch drive gear on joggler cam
shaft. These set screws are seated in undercuts on
shaft and must be loosened a full turn. Slide shaft out
of rear of unit.
6. Remove clutch assembly through bottom of
unit.
The clutch can now be dis-assembled and the
spring removed.
7. Re-assemble in reverse order. Be careful to
have the clutch latch and the detent in their correct
positions, and
the
grease fittings over the slotin the
shaft.
The clutch drive sleeve and
the
side joggler
cam should hold the clutch together, with the clutch
in full mesh.
The sleeve and the side joggler cam
should hold the clutch together, with the clutch in full
mesh.
The sleeve and the side joggler cam should
not squeeze the clutch so tightly as to cause binding
when the clutch is latched. Check all drive unit ad-
justments after the unit is replaced in the machines.
Service Checks
1. The front joggler interlocking arm should have
approximately 1/16" travel before contact makes.
2. The upper card deck support must be centered
between the side frames.
3. The front joggler operating levers must be
free of binds between the side plates and the lower
magazine.
4. Hopper bed plate springs must be 3/8"
±
1/16"
above hopper bed plate.
5. Shims are available to shim the lower maga-
zine if the speed nuts interfere with the helical spring
clutch.
6. The lower magazine throat should be .020" to
.040" above the imaginary plane determined by the
tops of the feed rolls (Figure 2- 9) .
Joggler Adjustments
Front Joggler
1. Turn the file feed drive unit until the front
joggler cam followers are on the low dwells of the
camS. Fill the hopper to just below the sensing pads
on the front joggler and close joggler. Set the ad-
justing screws on the joggler to just touch the
operating arms (Figure 2-10). Undertheseconditions
there should be .003" to .010" clearance between the
cards and the lower end of the joggling surfaces (the
lower end of the joggling surfaces is in line with the
top of the card feed knife posts). This clearance is
obtained by adjusting the hopper post mounting bar
with the set screw (Figure 2-10). The hopper posts
will now have to
be
adjusted (Refer to Hopper Adjust-
ments).
2. Turn the file feed drive until the frontjoggler
cam followers are on the high dwell of the cams. Fill
the hopper with cards to a level even with the top of
the sensing pads and close the joggler. Hold the rear
.020 TO .040

cam follower against the cam, and continue to operate
the unit. Stop when .005" to .008" clearance appears
between the cam follower arm and the adjusting
screws.
Loosen the clutch operating lever on its
pivot shaft and fully seat the clutch latch. With the
cam follower against the cam, position the clutch
operating lever so that it just touches the turned 'over
ear on the cam follower arm (Figure 2-10). Tighten
the set screws in the clutch operating lever, securing
it
to its shaft.
Side Joggler
1. With a two inch column of cards in the hopper,
turn the file feed drive until the hopper joggler cam
follower is on the high dwell of the cam. Set the
adjusting screw for .000" to .005" clearance between
the top of the deck and the joggler arm (Figure 2-10A).
NOTE: There is no timing relationship between the
side and front joggler cams, nor between the cams
and the feed knives. The front joggler cams should
however, be even with each other.
HOPPER AND PICKER KNIVES
Principles of Operation Figure 2-11.
After cards go from the file feed to the hopper, the
picker knives provide the means of moving the cards
from the hopper into the first set of feed rolls. A
picker knife cam assembly is located on a shaft driven
under clutch control.
Two cam follower arms are
clamped to an adjacent shaft that causes it to oscil-
late.
Two picker knife arms, also clamped to this
shaft, move the picker knife blocks.
