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.
