MAINTENANCE, REPAIR AND ADJUSTMENTS
ADJUSTING NOSE ASSEMBLY
These nose assemblies are factory adjusted to properly install rivets
in the A-Group (shorter lengths). If nose assembly has been
disassembled for repair it will be necessary to readjust it. Gages can
be purchased and are identified by their color: 1/8" No. 628-4 is
green; 5/32" No. 628-5 is red; 3/16" No. 628-6 is blue; and 1/4" No.
628-8 is plain.
SHIFT-POINT ADJUSTMENT
This adjustment determines the flushness of the broke pintail. After
the lock ring is set, the pintail should fracture substantially flush with
the rivet head.
1. If the stem breaks below flush, loosen cap screw (2) and turn set
screw (3) clockwise 1/4 turn (maximum). Tighten cap screw (2).
2. Test setting by installing rivet and repeat if necessary.
3. If stem breaks above flush, loosen cap screw (2) and turn set
screw (3) counterclockwise 1/4 turn (maximum). Tighten cap
screw (2).
4. Test setting by installing rivet and repeat if necessary.
5. If nose assembly is so far out of adjustment that it does not
respond to these 1/4 turn adjustments, it may be quicker to
remove the rocker arm (20) and shift slide (4) and reposition the
adjusting screw (3) to its approximate starting position outlined
under Assembly Instructions line 2.
ASSEMBLY INSTRUCTIONS
1. Replace any broken or worn parts. When reassembling drawbolt,
press in special washer (16) while inserting retaining ring (17).
When retaining ring is in place turn special washer until its lug is
positioned between the ends of the retaining ring.
2. If shift slide (4) has been removed from nose assembly for repair
or replacement, it should be repositioned by turning screw (3)
until it protrudes from the back of the slide 3/16" to 7/32". With the
shift slide pressed snugly against rear of drawbolt (5), run cap
screw (2) in until tight. Shift slide will then be in approximately the
correct operating position, but may require minor adjustments as
shown in the shift point adjustment instructions.
3. Apply a coating of high pressure grease, such as Lubriplate®
130AA, to the top and bottom of drawbolt (5) and to the bottom
of rocker arm (20). Reassemble nose.
DISASSEMBLY INSTRUCTIONS
1. Loosen jam nut (28) and remove adapter sleeve (30). Remove
drawbolt adapter (29).
2. Remove four button head screws (25) and lift off cover (1).
3. Remove retaining ring (22), button screw (25), guard (24) and
pivot pin (23). This will allow rocker arm (20), anvil (21) and
drawbolt (5) to be removed from sleeve assembly (27).
4. To disassemble drawbolt, remove retaining ring (17) and
washer (16). The stem stop (8), jaws (9), ejector (10), spring
(11),follower (12), seat (13), spacer (14) and spring (15) will then
come out of rear of drawbolt.
5. It is not usually necessary to remove the shift slide (4), stop block
(6) or outer anvil (18), but if any of them have been damaged
they may be removed by loosening screws (2), (7) and (19).
CLEANING NOSE ASSEMBLY
It is important that the nose assembly be kept clean, especially
around the riveting end, as adhesives, chips, sealants, etc. Will
clog the serrations of the jaws and cause slipping. The outer anvil
and the inner anvil must be kept especially clean since foreign mat-
ter can build up and keep the anvil from going all the way forward
to set the locking collar in the rivet.
An occasional application of good grade high pressure grease,
such as Lubriplate 130AA, to the bottoms of the drawbolt and rock-
er arm will prolong the life of these parts.
INNER ANVIL ADJUSTMENT
1. When adjusting nose assembly, either on or off tool, make sure
the drawbolt 5) is in the full forward position.
2. Push rocker arm (20) back toward drawbolt so it will rest on shift
slide (4).
3. Insert short end of setting gage into outer anvil (18) until inner
face of gage collar rests against end of inner anvil (21) and anvil
rests on crossbar in sleeve. Outer face of gage collar should be
approximately .010 above face of countersunk head outer anvil
or approximately .010 above bottom recess on universal head
outer anvil.
4. If adjustment is required, loosen set screw (19) and turn outer
anvil (18) for proper positioning.
5. Tighten set screw (19) snugly to prevent anvil from Getting out of
adjustment.
