Transport And Stackers; Chute Blade And Selector Magnet - IBM 1402 Reference Manual

REPLACEMENT
1. Re-install stripper assembly in original position
on punch unit.
2. Check that toes of punches retract .003" to .006"
into stripper. See Figure 3-34. Adjust by adding
or removing shims 437964 between the stripper
assembly and punch unit side frame. ( Shim
437964 is .003" thick. )
Caution: If toes of punches retract more than
. 006" within stripper, heels of punches may shear
stripper plate.
3. Adjust retainer plate for .005" to .013" clearance
between plate and punches. See Figure 3-34.

ADJUSTMENTS
1. Lower control key and indicator light panel by
loosening four screws.
2. Adjust chute blades, with chute blade mounting
screw, for 1/32"
±
1/64" clearance between end
of lower chute blade and lower card guide plate.
See Figure 3-38.
3. With pocket selector magnet armatures attracted,
adjust each armature for .035" ± .003" clearance
between upper part of armature and stop. See
Figure 3-37 .
4. Adjust selector magnet assembly (by means of
the mounting screws) to position the chute
blades 1/32"
+
1/64" - 0 above card line when
the magnets are not energized, and 1/32"
+
1/64" -- 0 below the card line when the magnets
are energized. See Figure 3-37.
5. Adjust chute blade tension so that a force of 150
to 350 grams, applied to the 2 or 8 selector mag-
net armature at a point just under armature
backstop, holds the armature fully attracted. A
force of 75 to 200 grams should hold select
magnet 1 or 4 armatures fully attracted. See
Figure 3-37.
6. With chute blade removed and held on Hat sur-
face, tab, containing chute blade mounting
screw hole, should project 1/8"
±
1/64" above
Hat surface.
7. Position selector magnet deflector spring for
.005" to .010" clearance above lower card guide.
See Figure 3-37.
