The Huck 507 inline Hydraulic Installation Tool
installs C50L HUCKBOLT®Fasteners and HLC50L
HUCKLOK®Fasteners. When equipped with the proper
(optional) nose assembly, it can install:
-32 (1” diameter) and
-36 (1-1/8” diameter) fasteners.
Each tool has a cylinder and piston assembly. A relief
valve, designed to relieve the hydraulic pressure at
both ends of the stroke, is situated near the piston.
The pintail ejector ejects broken pintails from the nose
assembly. The end of the piston rod is threaded, and
a nose adapter and retaining rings are included for
attaching nose assemblies.
The operating pressures for the 507 tool are:
• PULL: 5400–5700 psi (372–393 bar) and
• RETURN: 2200–2400 psi (152–165 bar)
as supplied by a Huck POWERIG®Hydraulic Unit,
models 940 and 918—or an equivalent hydraulic unit.
The correct PULL and RETURN pressures are
important for the proper function of the tool and Nose
Assemblies, as well as for the safety of the operator.
Huck has available a gauge (P/N T-124833CE) for
checking hydraulic pressures; instructions for its use are
included with the gauge and the POWERIG.
UPDATING OLDER TOOLS
Changes were made to the 507 tool, starting with serial
number 0847. Replacement parts are still available for
the earlier models. If your tool’s serial number is lower
than 0847, Huck recommends that the tool be updated
to the current configuration. Call your Technical Support
representative for the part numbers.
OPTIONAL ACCESSORY
A Suspension Bracket that alleviates operator fatigue
is available from Huck. When the bracket is used with
a balance spring suspension system, much of the
tool’s weight is supported. Contact Huck Customer
Service for the part number and availability. See KITS &
ACCESSORIES.

PRINCIPLE OF OPERATION
Piston Relief Valve Trigger
Ejector Rod
Hydraulic Hoses
to Powerig
When tool hoses and cord are connected to POWERIG
hoses and control cord, PULL and RETURN strokes of
tool are controlled by a Trigger in the handle.
When the trigger is pressed, a solenoid-operated valve
in the POWERIG directs pressured fluid through the
FILL Hydraulic Hose to the front side of piston, and
allows fluid on the RETURN side to flow back to tank.
The piston and nose assembly collet moves rearward
causing follower O-rings and/or spring to impart a
forward motion to the follower.
If tool and nose assembly is in position on a fastener pin
and collar, this forward motion causes the jaws to clamp
onto pintail of fastener and installation cycle begins.
Clamping pressure is applied to the sheets. The anvil is
forced forward, swaging the collar into locking grooves
of the fastener.When the anvil hits the sheet, continued
pull causes the pintail to break off. When the Piston
reaches the end of its PULL stroke, it uncovers flats
on the rear end of the Relief Valve. These flats were
designed to provide a passage for hydraulic fluid from
PULL side to RETURN side of piston, “unloading”
(“dumping”) the pressurized fluid back to tank.
When the trigger is released, the solenoid is
de-energized and the valve directs pressurized fluid to
rear side of the piston and allows fluid on PULL side to
flow back to tank.
This causes piston and collet to move forward and
pushes nose assembly and tool off the swaged
(installed) fastener. Nose assembly jaw release contacts
jaws, causing them to open and release the broken-off
pintail. The Ejector Rod hydraulically ejects the pintail
out the front of the nose assembly. When the piston
reaches the end of its RETURN stroke, pressure is built
up causing the POWERIG idler valve (except on models
910 and 911) to go to idling pressure. Idling pressure
keeps the tool piston and nose assembly collet, jaws,
etc. in the forward position ready for the next installation
cycle.
A flat on the front end of the relief valve was designed
to provide a passage for hydraulic fluid from RETURN
side of piston to PULL side of piston and back to tank.
When tool hoses and cord are connected to POWERIG
WARNING: Huck recommends that a Huck
POWERIG®be used to power Huck tools.
Hydraulic power units that deliver high
PULL and RETURN pressures—but which
are NOT equipped with RELIEF VALVES—
are specifically NOT RECOMMENDED and
may be dangerous.
Set the PULL and RETURN pressures
as specified in SPECIFICATIONS. Failure to
properly set these pressures may result in
serious personal injury.
Huck Pressure Gauge (P/N T-124883CE) is
available, and should be used as indicated
in its instruction manual.
