4068
Hydro-Pneumatic Blind Rivet Nut and StudInstallation Tool
INTRODUCTION
This brochure covers the use and maintenance of the Cardinal Components 4068 spin-pull-spin
blind rivet nut and stud installation tool. This tool is capable of placing Bollhoff Rivkle brand
blind rivet nuts in sizes from M3 metric - #6 unified, up to M12 metric – ½” unified; as well as
blind rivet nuts of other suppliers. The specific capabilities of this tool, when used with other
suppliers’ inserts, should be discussed with the Cardinal Components technical sales department.
The 4068, with a minimal amount of care, if kept clean, lubricated and operated properly for
the size inserts being installed, will provide many years of service.
The basic function of this tool can be best understood by realizing it is capable of two
separate operations – spinning and pulling.
The spinningis performed bythe 4068 in both a forward motion, to mount the unplaced rivet
nut onto the threads of thedrive mandrel, and a reverse spinto disengage the drive mandrel
from the installed insert.
Once the tool has been properly set, installation of the blind rivet nut is accomplished by –
forward spin to mountthe insert onto the tool, pullbackto cause the insert to upset – reverse
spin to disengage the tool from the installed insert.
The forward spinning operation of the tool is automaticallystarted when pressure is applied to
the drive mandrel. Byholding the insert with its head toward the nosepieceor anvil of the tool
and applying pressure on the mandrel, the forward spin begins, mounting the insert on the
tool. The forward spin will stop when the insert meets the face of the nosepiece or anvil.
By pulling down on the bottom half of the “rocker” trigger, the pull stroke is performed.
By depressing the top half of the rocker trigger, the reverse spin begins to disengage the tool
from the installed insert.
The 4068 delivers a constant pulling force, or traction power, which at 85 psi. air pressure, is
5000 pounds of force. The proper installation of any size blind river nut is thereby
accomplished by a strict control of the stroke distance of the tool – the distance the tool will
pull back on the mandrel. It is extremely important that this stroke distance be properly set
duringthe initial setup of the tool priorto beginning anyinstallation of any size blind rivet nut.
The pulling force or traction power of this tool is capable of damaging the threads of the
insert, or even stripping the threads of small inserts, if not properly set.

CAUTION – DISCONNECT THE AIR SUPPLY FROM THE TOOL BEFORE
MAKING ANY ADJUSTMENTS!
The 4068 should be operated with filtered, lubricated air from 70 to 100 psi (5 – 7 bar).
In setting the 4068 tool, there are three critical aspects to consider:
1. Check the size. Ensure the correct mandrel (#25) and anvil (#23) are installed on
the tool for the insert being installed.
2. Set the anvil position. Make sure the anvil (#23) is properly set to ensure the
correct length of mandrel extends from the anvil for the specific size RIVKLE being
used.
3. Set the stroke distance. The correct stroke distance must be set on the tool,
taking into consideration the specific RIVKLE being installed and total material
thickness it is being installed into. It is very important to ensure that RIVKLE blind
rivet nuts are properly installed andalso to avoid damage to the insert from over
stroking the tool.
For the setup of the 4068, a 19mm open end wrench or spanner as well as a 6mm pin punch
are required. A combination tool is included with the 4068 for setup and for changing the
mandrel and anvil.
Assuming the 4068 has the proper size anvil and mandrel installed, the tool must be properly
set up for installation of the specific size RIVKLE being used, by first adjusting the anvil
position.
SETTING THE ANVIL POSITION
For open end RIVKLE inserts, the anvil (#23) should be set so that when the RIVKLE being
used is threaded onto the mandrel, the face of the anvil is flush against the head of the insert
and theend of the mandrel is flush with the shankend of the RIVKLE.
Adjustment procedure
1. Disconnect the air supply from the tool.
2. Screw the anvil lock nut fully onto the anvil.
3. Screw the anvil and lock nut onto the nose piece as far as it will go.
4. By hand, thread the open end of the RIVKLE onto the mandrel until all threads are
engaged and the end of the mandrel is flush with the shankend of theRIVKLE.
5. Hold the RIVKLE to prevent turning and begin unscrewing the anvil until the face of
the anvil contacts the head of the RIVKLE.
6. Hold the anvil in this position while tightening the lock nut against the nose piece.
Torque lock nut to 7 foot/lbs. (10 NM).
NOTE: For closed end RIVKLE, at step 4 above, thread the RIVKLE fully onto the mandrel
until the threads bottom out, then loosen one turn.

Adjusting the stroke distance
To determine the proper stroke distance required for a correct installation of RIVKLE blind
rivet nuts, refer to the Rivnut Design Catalog page for the specific RIVKLE being installed.
Note the “S” dimension reference (if indicated as a range, usethe minimum) forthe size being
installed, as well as the maximum grip capacity of that specific RIVKLE.
Measure the total thickness of the material into which the RIVKLE is being installed.
STROKE DISTANCE IS DETERMINED BY THE FORMULA:
STROKE DISTANCE = “S” (min.) +(maximum grip – material thickness) .
EXAMPLE: An M6 RIVKLE # 2330-1060-030, is being installed into a steel sheet 1.5 mm
thick. The “S” dimension for this size RIVKLE is indicated as a range of 2.2 – 4.7mm;
therefore we use the “S” minimum of 2.2 mm. Themaximum grip of this RIVKLE is 3.0 mm
and the actual material thickness is 1.5 mm. Applying these figures to the formula, we can
calculate the proper stroke distance:
Stroke = “S” (min) + (Max grip – material thickness)
Stroke = 2.2 + (3.0 -1.5 )
Using the above example, the result is 3.7 mm stroke distance.
Adjusting the stroke distance
1. DISCONNECT THE AIR SUPPLY FROM THE TOOL.
2. Set the anvil position first (see previous page).
3. Hold the adjusting ring (#38) and unscrew the nose piece (#24) a few turns.
4. Turn the adjusting ring (#38) counter clockwise, toward the (-) minus direction until it
stops. The stroke distance of the tool is now set at zero.
5. Increase the stroke distance setting by rotating the adjusting ring in the (+) plus direction.
NOTE: ONE REVOLUTION OF THE ADJUSTING RING EQUALS 1.5MM (.060”) OF
STROKE DISTANCE ADJUSTMENT.
6. To test the stroke distance setting on the tool, measure an unplaced RIVKLE from the flat
of the head to the end of the shank. Mount the RIVKLE on the tool and upset the insert.

Remove the upset RIVKLE from the tool and measure it again, from the head to the end of
the shank. The difference in the overall length, before upset and after, is the present
stroke setting of the tool.
7. To verify that this setting is correct for the application, install the RIVKLE in a sample
sheet of material. Measure the shank length on the back side of the material and compare
this to the “L2” dimension noted in the Rivnut Design Catalog page for this specific insert.
Adjust the stroke length as needed to achieve the proper “L2” dimension.
To set up the tool for different RIVKLE diameters, it is necessary to change the anvil and
mandrel.
Changing the Mandrel
1. MAKE SURE THE AIR SUPPLY IS DISCONNECTED FROM THE TOOL.
2. Hold the nose piece (#24) of the tool stationary and loosen the anvil lock nut. Remove the
anvil & lock nut from the tool.
3. Hold the adjusting ring (#38) stationary. Unscrew and remove the nose piece (#24).
4. Using a pin punch and small hammer, push out the mandrel pin (#26). Be careful not to
damage the spring ring (#30). Remove the mandrel from the tool.
5. Slide the new mandrel into position, align the holes and reinstall mandrel pin (#26). The
pin is held in place by the spring ring.
6. Reinstall the nose piece (#24).
7. Reset anvil position and stroke setting per previous instructions for the new RIVKLE to be
installed.
8. Tighten nose piece to approx. 11 foot pounds (15NM) torque.
Checking and filling Hydraulic Fluid
Recommended Oil : Mobil DTE (ISO VG68), Hydrolub 68 Codat or

3. Retract the air piston in the lower chamber by inserting a heavy wire (coat hanger or
similar) into the vent hole and gently press the piston fully down. Or, inject compressed air
into the vent hole to move the piston down.
4. Check the oil level in the oil fill hole (#31). Top up as necessary until the oil reaches the
bottom of the threaded hole.
5. Reinstall the fill plug and vent cap.
6. Connect air supply and actuate the tool several times.
7. It may be necessary to repeat the above procedure 2 – 3 times to purge all air and allow
the oil level to stabilize.
Suggested Daily Checklist for Production Use of the 4068 Tool
1. Check the spin – pull – spin operations by pressing on the mandrel, then actuating the
bottom and top of the rocker trigger, without a RIVKLE on the tool.
2. Check the security of the anvil and nose piece.
3. Thread the RIVKLE onto the tool, check that it threads fully up to the anvil and all threads
are engaged.
4. Always hold the tool 90 degrees to the work piece.
5. Lubricate the mandrel after every 300 RIVKLE operations.
6. Never upset the same RIVKLE twice. This may damage the insert or the mandrel.
After use, protect the mandrel by threading on a RIVKLE.
Releasing the Mandrel When Locked Into an Installed Insert
A common problem in the installation of rivet nuts is that the mandrel may become locked
into the internal threads of a blind rivet nut. This condition may be caused by the wrong insert
being used in an application, the installation tool not being properly set, or if the operator is
not installing the insert correctly (not having the insert head resting on the material surface).
With most competitive installation tools, this condition requires a long and difficult process to
free the jammed mandrel. Because of the 4068’s unique design, it is a simple and quick
procedure.
Procedure to clear a stuck mandrel:
1. DISCONNECT THE AIR SUPPLY FROM THE TOOL.
2. With the mandrel (#25) locked into the installed threads, turn the tool until the mandrel pin
(#26) is visible through one of the cutouts in the nose piece (#24).
3. Use a pin punch to push out the mandrel pin (#26).
4. Unscrew the nose piece from the tool. The tool body is now free from the stuck mandrel.
5. The mandrel can now be removed from the installed insert.
