Bell DATASPEED 40 Adjustments And Lubrication page 3

1.07 Some adjustments require access to
subassemblies that have to be removed.
For removal of these subassemblies, see Section
582-210-702.
1.08 The adjustments for the printer are
arranged in a sequence that should be
followed if a complete readjustment of the
printer is undertaken. A complete adjustment
procedure should be read before attempting to
make the adjustment. After an adjustment has
been completed, be sure to tighten any nuts or
screws that may have been loosened to facilitate
the adjustment, unless otherwise instructed.
1.09 The belt tensions given in this section
are indicated values and should be
checked with proper spring scales. The adjusting
illustrations, in addition to indicating adjustment
tolerances, show the angle at which the scale
should be applied when measuring belt tensions.
1.10 Some of the adjustments require the
printing of the font identification charac-
ter. This character is printed when the printer is
running and the TEST switch is placed in the ON
position. The associated printer cover Interlock
switch must be disabled (bypassed) for printer
operation.
1.11 All tolerances in the adjustments in this
section unless otherwise stated, are in
inches.
1.12 When a requirement specifies a disen-
gaged clutch, the clutch must be fully
latched so that the clutch shoes are completely
disengaged from the clutch drum. To become
fully latched, the trip lever (or stop
arm,
must
engage the clutch shoe lever, and the clutch disc
must rotate far enough to permit the latchlever
to fall into the notch in the clutch disc.
1.13 When rotating the clutch shaft of the
printer by hand, the clutch does not fully
disengage upon reaching its stop position. In
order to relieve the drag on the clutch drum and
permit the shaft to rotate freely, apply pressure
ISS 3, SECTION 582-210-700
to the stop lug on the clutch disc with a screw-
driver until the latchlever falls into its notch on
the clutch disc. The internal expansion clutch is
then fully disengaged. This procedure should be
followed before placing the printer in its cabinet
and switching on the power.
1.14 When engaged, the clutch shoe lever is
unlatched (tripped), and the clutch shoes
are wedged against the clutch drum.
1.15 Lubricate the printer just prior
to
placing
in service or before· putting it in storage.
The printer should be relubricated after it has
been in service a few weeks. Thereafter, lubricate
the mechanisms every 2,000 hours of running
time or one year, whichever occurs first.
1.16 The general lubrication requirements con-
sist of using KS-7470 oil at all locations
where the use of oil is indicated and Mobile No.2
grease on all surfaces where grease is indicated.
Thoroughly saturate the felt oilers and remove all
excess oil by wiping lightly with a clean cloth.
The friction surfaces of all moving parts should
be thoroughly lubricated.
1.17 Symbols 01, 02, 03, etc, refer .to 1, 2,
3, etc, drops of oil. The following list of
symbols applies to the lubrication instructions:
o
Oil KS-7470.
G Apply thin film of Mobile No.2
(145867) grease.
S Saturate felt oilers, washers and wicks
with oil.
D Keep dry, no lubricant permitted.
1.10 Overlubrication which would allow oil
to
drip or grease to be thrown on other parts
should be avoided. Capillary action and vapori-
zation tend to keep a thin film of oil on the
mechanisms. This prevents rust and provides
sufficient lubrication to many points.
1.19 Closed ball bearings do not require lubri-
cation. All open ball bearings should be
packed with grease (TKS-103, 195298).
