is below 90 psi.
When you are driving 1/8-inch-
diameter rivets, it maybe necessary to use an air inlet
bushing, part number 82642, that has a 0.040-inch
inside diameter. If the tool “flutters,” reduce the line
pressure to 60 psi with an air regulator, part number
900-102, attached to the air inlet bushing.
When you are using a CP350C rivet pull tool to
drive 1/16- and 5/32-inch-diameter rivets, use the air
inlet bushing, part number 81479, and the shift valve
stop, part number 83731. When you are driving
1/8-inch-diameter rivets with the CP350C, use the air
inlet bushing, part number 83642, and reduce the line
pressure to 60 psi with an air regulator, part number
900-102, attached to the air inlet bushing.
The equipment used for the installation of
cherrylock rivets is similar to the buck rivet. See
figure 13-50. The operation and adjustment of the
pulling heads are preset during manufacture. If
further adjustment should become necessary, the
procedures provided with the head or in the
maintenance manual should be followed. To install a
pulling head of the H615A series, engage the threaded
portion of the pulling head sleeve cap and drawbolt to
the gun head and drawbolt. Then tighten the screws
and the jam nut. The pulling head of an H640A series
is installed by engaging the internal threads of the
head piston rod. Then align the holes in the pulling
head with those on the gun adapter, and tighten one
setscrew.
To install the nose assembly used on the hydro-shift
head equipped gun (fig. 13-5 1), you should proceed
as follows:
1. Remove the retainer nut from the hydro-shift
head.
2. Place the jaw assembly in the collet (with the
spring protruding).
3. Screw the internal threads of the collet onto
the drawbolt of the hydro-shift head.
4. Slip the sleeve assembly over the collet.
5. Place the retainer nut over the sleeve assembly
and tighten it onto the gun.
Cherrylock rivets require a separate pulling head
for each diameter and head style. Each series of gun
also uses a different set of pulling heads. Refer to the
appropriate operating manual for the proper head for
each rivet and gun.
There are also special use cherrylock pulling
heads (fig. 13-52) for use in areas where access is
limited.
