Maintenance Intervals
Machine Maintenance Procedures
1. Sliding surfaces must be kept free of dirt and other abrasive
materials.
2. All exposed black metal surfaces should be coated occasionally
with a light film of oil to prevent corrosion.
3. Periodically check the oil level in the fluid reservoir of the
hydraulic unit. Add pump manufacturer’s hydraulic oil as
needed.
NOTE: Completely retract the cylinder when check¬ing the oil
level.
Die Cage Maintenance Procedures
1. Lubricate the die cage. For maximum service, FT1370 die cages
require lubrication at 30-crimp intervals with high efficiency
PTFE grease (Danfoss part number T-400-G). FF91455 is an
16-ounce container that will provide sufficient lubricant for
about 10,000 crimps.
Periodically remove PTFE grease residue that has built-up on
the sides of the dies and the crimp ring during the crimping
process. PTFE grease residue becomes contaminated with
metal and plating chips and airborne contaminants, which can
cause pre-mature wear of the dies and crimp ring. It should
carefully be removed without mixing it with newly applied
PTFE grease.
2. Die Cage maintenance should be performed at 1000-crimp
intervals or every six months, which ever occurs first. Die cages
should be clean of grease and debris and inspected for worn
or damaged components.
a. The sliding surface of the dies should appear smooth with
no apparent galling. Galled dies must be replaced.
Individual dies in a cage can be replaced without
replacing all eight dies.
b. Replace springs that show any sign of damage or collapse
(are shorter than other springs).
c. The spring plate should appear smooth with no apparent
galling. Galled spring plates must be replaced.
d. Inspect remaining components and replace those that are
badly worn.
Reassemble components and liberally apply PTFE grease to the die
surface which slides along the spring plate. Torque the die cage
bolts to 50 in.-lbs.
Ensure that all dies slide in and out freely.
