How to adjust pockets on a 489 machine
When the pockets on a 489
machine are out of alignment the result will be a mis-feed of the eyelet. The
mis-feed will result in the eyelet being spit out of the machine onto the floor.
This occurs when the spindle in the top die does not go directly into the center
of the eyelet. The pockets must be positioned so that when an eyelet is fed
from the raceway it is correctly positioned in the pockets (figure 2). The following
is the procedure to align the pockets correctly:

UNPLUG THE MACHINE BEFORE MAKING ANY ADJUSTMENTS. ALL ADJUSTMENTS SHOULD BE MADE AND CHECKED WITH THE MACHINE BEING TURNED OVER BY HAND - NOT UNDER POWER.
The first thing
that needs to be checked is the alignment of the raceway and the top die. With
the pockets off the machine first check the raceway alignment as follows: When
the top die is at its furthest point of travel down, it should be directly in
the center of the rails. If it is not, loosen the raceway screws that hold it
to the machine and adjust accordingly. Once the raceway is centered, attach
the pockets to the pocket holder and attach it to the machine.
On the diagram above (figure "1"), part A should be lined up just
below the raceway, about 1/32 to 1/16 of an inch gap. On Figure 3, the two arms
of the pockets should be in line with the two rails on the outside of the raceway.
Part "B" above SHOULD NOT TOUCH THE RACEWAY AT ALL. It should be approx.
1/16 of an inch from the tip of the raceway. If after lining up the pockets
so that the spindle fits the inside of the eyelet correctly (see below) Part
B is touching the raceway, part B will need to be ground down so the pockets
can be brought closer in toward the raceway if necessary.

As the top
die comes down, it should split the two arms of the pockets equally - the spindle
should go straight thru the center of the eyelet. When the eyelet is sitting
in the pocket the eyelet should be all the way against the inside edge of the
pocket as in the diagram above ( Figure "2"). When the top die comes
down thru its cycle, the spindle inside the top die should pass directly thru
the center of the eyelet. If it does not and it hits the flange of the eyelet
it will usually toss the eyelet onto the floor. To correct this you may have
to shim the pocket holder to move it out away from the raceway. or tap the pocket
holder with a hammer to bring it closer to the raceway. BE CAREFUL NOT TO BREAK
THE POCKET HOLDER OR THE POCKETS THEMSELVES. Tap lightly!
