8. Lubricate the liner pin bushings.
9. Reassemble the die package and place it in
storage or back in service.
NOTE
i
White lithium grease should used instead of the
silicone or oil if the die package is to be stored for
any length of time. The lithium grease must be
removed and the silicone or oil be applied before
the die package is placed back in service.
10. Document this maintenance in your
Maintenance Log.
5. REPAIR AND REPLACEMENT

5.1. Tooling Required for Repair
— Set of (standard) hex key wrenches
— Set of drift punches (¹/₈–in. dia to ¹/₂–in. dia)
— Metal spacer blocks (to set the top assembly on
in order to prevent the liner pins from touching the
work table)
— Depth micrometer or equivalent measuring
device
— Die Repair and Sharpening Log for the die
package (as found in the documentation package
for the dies)
5.2. Die Package Disassembly
NOTE
i
If it is necessary to stagger the lengths of the
perforators be sure to maintain the staggered
relationship during any repair.
DANGER
Die assemblies are heavy. To avoid personal
injury, always use a hoist when lifting or moving
the die assemblies.
1. Remove the upper assembly (punch holder)
from the lower assembly (die block). Use a hoist if
available. See Figure 2.
2. Carefully set the top assembly on spacer blocks,
high enough so that tips of the liner pins do not
touch your table. See Figure 3.

3. Remove all transfer pins (pressure pins).
4. Remove shoulder screws for solid stripper. Be
sure to block “up” the stripper, otherwise it will fall
when the last bolt is removed.
5. Remove shoulder screws from stop block
assemblies. Remove the mounting screws holding
the liner pins in place. Carefully tap the liner pins
(completely) out.
6. Remove the guide pins, pilots, stop blocks and
front handle assembly from the lower assembly.
See Figure 4.
