Troubleshooting Procedures
Troubleshooting Coll-O-Crimp T-421 U Electric Pump
IMPORTANT: Pressure must be relieved from system before disconnecting hose, installing gauge or removing valves from pump.
Step 1:
Check fuse, loose wire connections, switch malfunctions or for
damaged cord. Pump electric cord must be plugged into a
grounded 220 volt, 60 cycle, single phase outlet on a 15 amp
fused electrical circuit.
Step 2:
Check oil level - after assembly and system has been purged
of air the fluid level should be 1/2” from top of reservoir. Clean,
anti-wear type, hydraulic oil having a (ISO 32) 300 SSU/100°F
is recommended. Use only if operating temperature is below
0°F or above 160°F. (See current 411 catalog for oil types.) Oil is
needed to:
1) Transmit power easily through system
2) Lubricate moving parts
3) Provide seal clearances between parts
4) To cool or dissipate heat
Step 3:
Clean or Reset Relief Valve - A 6000 PSI pressure gauge, a 5/16”
Allen wrench, a 1” socket and a screwdriver are required. Remove
cap from relief valve. Remove adjustment screw, spring and
ball. Ball should be attached to spring. Check ball and seat for
possible scoring. Replace spring and ball in cavity. Insert a small
punch through spring against ball. Give punch a moderate tap
to seat ball. Return adjustment screw to original position making
sure adjustment screw is at least one turn from bottoming.
Remove 3/8” NPTF plug from port above checkvalve and install
a 6000 PSI pressure gauge. With 6000 PSI pressure gauge in
place, operate unit to full crimping position. Gauge should read
4000-4200 PSI. To raise setting, turn screw in (clockwise); to lower,
turn screw out (counterclockwise); in 1/4 turn increments. After
each adjustment, recycle and read gauge for proper setting. Run
a cycle of the crimping system for final gauge reading before
removing gauge and reinstalling pipe plug.
Step 4:
Shuttle Valve - If the shuttle valve is in a closed position and
Coll-O-Crimp pusher will not retract it may be helpful to tap the
shuttle valve cap several times to dislodge any silt that may be
causing stem to bind. If this does not free valve and allow pusher
to retract use extreme caution prior to proceeding with shuttle
valve removal as the system is still under pressure. It may be
advisable to relieve pressure at a hose connection to avoid an
oil bath. After pressure is removed from system, remove cap and
valve cartridge. Soak cartridge in a PETROLEUM BASED SOLVENT
ONLY (clean Stoddard solvent). Do not use Triethene, Gasoline or
Paint Thinner as they will damage the 0-Ring Seals. If cartridge
disassembly is required, use care in removing stem as it has a
.0005 metal seal fit. Rotate stem in solvent and push from seat
end to remove from cartridge. Do not lose the loose ball. Wash
parts in clean solvent and examine for any surface markings. If
necessary polish with a fine crocus cloth. After final cleaning,
reassemble cartridge. Shake cartridge and check for free
movement of ball and stem. Replace cartridge if not functional
at this point. Reassemble shuttle valve into its cavity and check
crimping cycle prior to using system.
